Powerbox Announces Ruggedized Dual Channel Power Supply for Marine Engine Control
Posted: 2020-4-3

Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, has announced the release of a new dual channel power supply for Marine engine control. Based on a ruggedized platform for use in harsh environments, the ENMA500D24/2x27-CC provides two 27V/20A isolated outputs and a total power of 540W. The power supply is housed in a robust IP56 case, it is mechanically designed for efficient conduction cooling, and it complies with DNV/GL standards.

From local low power DC/DC converters powering sensors to high power DC generators powering the whole boat, ships and vessels are full of electrical and electronic equipment requiring robust and safe power supplies. Although many applications can be powered by marine certified commercial off-the-shelf (COTS) power supplies, others are very specific, requiring unique power solutions designed to pair with the final application.

One example being the servomotors used to operate Fast Switched Valves (FSV) like the ones used for safety purposes in fuel injection pumps, orientable propellers, and engine control.

FSV operation is based on servomotors ensuring that fluids are transferred or interrupted with the highest level of safety. As failure is simply not an option in such types of equipment, FSV manufacturers often use two independent power supplies to guarantee redundancy. However, considering the equipment is installed in very compact and harsh environments, this can be a challenge for the installer.

With high levels of expertize in designing power solutions for the marine industry to DNV/GL standards, PRBX has developed the highly integrated, isolated, dual channel DC/DC converter, the ENMA500D24/2x27-CC.

Because they are often used in harsh environments, the ENMA500D24/2x27-CC is built in a robust IP56 case, resistant to high-pressure and heavy sprays of water. Being sealed to comply with IP56, the ENMA500D24/2x27-CC DC/DC converters have been designed and optimized for conduction cooling. Two lateral heatsinks facilitate the thermal exchange between the inner dissipating components and the ambient outside.

福建快3计划Powered by the low voltage 24V distributed supply to electronics equipment, the ENMA500D24/2x27-CC can tolerate a wide operating range of 18 to 36V, and is able to accommodate a large voltage drop down to 10V for 10 seconds. The ENMA500D24/2x27-CC delivers 27VDC / 20A and a total power of 540W and has an efficiency superior to 85%.

Typically used for safety equipment requiring redundant power sources, when redundancy is not required but the application requires two independent outputs, the ENMA500D24/2x27-CC offers two 27VDC fully isolated outputs。 In that case the total output power remains at 540W though it can be balanced from 540W on one output and no load on the second to any mix between the two whilst remaining within the maximum power allowed。

The ENMA500D24/2x27-CC is protected against input reverse polarity, output short-circuit and includes over-temperature, over-voltage and over-current protection。  It is designed according to EN60068-2-x and complies with the safety standard EN 60950。

The module’s input voltage ranges from 85 V to 264 V, while its output voltage ranges from 42 V to 58 V. Transphorm’s TPH3205WS GaN devices are used in an interleaved bridgeless totem-pole PFC to achieve 98 percent efficiency at half load. The GaN devices lower the power module’s switching and driving losses, leading to the ZHR483KS outperforming preceding modules that used superjunction Silicon MOSFETs.

“We sought a power transistor that would enable us to develop a more efficient yet cost-effective solution for our customers,” said Dr. Guo, CTO, HZZH. “We considered Silicon Carbide devices but could not achieve the desired advantages at low voltages. We then vetted several GaN manufacturers’ devices, and ultimately selected Transphorm’s GaN FETs due to their reliability, device cost, and simple implementation.”

Transphorm’s GaN FETs are two-chip normally-off devices available in standard TO-XXX packages and PQFN modules that can be driven with common off-the-shelf drivers. The current Gen III family offers the GaN semiconductor industry’s highest threshold voltage at 4 V and highest gate robustness at ±20 V. These features enable customers to easily design in highly reliable GaN solutions to gain the technology’s high-power density benefits.

福建快3计划“Transphorm develops each generation of its GaN platform with four key factors in mind: reliability, drivability, designability, and reproducibility,” said Kenny Yim, Vice President of Asia Sales, Transphorm。 “We’re proud that HZZH selected us as its GaN partner as it affirms that those four factors are what our customers need to disrupt their markets。 They result in our GaN being designed into a wide range of multi-kilowatt power systems that are setting industry records。 We anticipate HZZH will continue to innovate as our collaboration continues on future products。”

The ZHR483KS is currently in production.

Known for exceptional efficiency – up to 94% efficient across line and load, PowiGaN technology is also extremely robust, making them highly resistant against line surges and swells commonly seen in regions with unstable mains voltage. This enables OEMs to specify a single power supply design to be used worldwide. Applications for the new parts include USB PD and high-current chargers/adapters for mobile devices, as well as set-top boxes, displays, networking and gaming products and appliances – especially those aiming to comply with the planned European Energy Labeling Regulation.

Comments Chris Lee, director of product marketing at Power Integrations: “We have experienced increased demand for our efficient AC-DC converter ICs with the highly robust 750 V GaN transistor. Simultaneous electrical strength and efficiency are difficult to achieve due to the relationship between Silicon MOSFET breakdown voltage and COSS-related switching loss. Our electrically strong PowiGaN transistors have very low COSS, so achieving over 94% efficiency and low field return rate from tropical markets is very straightforward.”

Posted: 2020-3-7
Thinner than a dime, available in custom values and shapes。

The new PPC Series of ultra-thin polymer aluminum electrolytic capacitors from Cornell Dubilier represents a totally new capacitor form factor. Designed specifically for applications requiring high ripple current and the thinnest possible profiles, type PPC opens up new product design options. In addition to being just 1 mm thin, the PPC uses versatile packaging technology that makes it possible for capacitors to be formed into custom shapes and sizes to accommodate available space.

“A single PPC capacitor offers capacitance and ripple current equivalent to dozens of SMT capacitors or a bulky cylindrical device,” said Mario DiPietro, Product Manager at Cornell Dubilier.  As an example, the company claims that a single PPC capacitor is equivalent to a parallel bank of 50 or more polymer tantalum capacitors and occupies one fourth the height. Also, circuit reliability is improved by using a single component versus an entire array of SMT capacitors.

Developed by Cornell Dubilier, the PPC is the latest leading-edge capacitor development by the company. These designs have been responsive to market demands for capacitors that provide higher performance while breaking away from traditional cylindrical form factors.

Powerbox Announces High Peak Load Power Supply for Medical Laser Applications
Posted: 2020-1-29

Powerbox, one of Europe’s largest power supply companies, and for more than four decades a leading force in optimizing power solutions for demanding applications, has announced the release of its new power supply solution for high peak load applications in the medical sector. Based on digital control and high energy storage management techniques, the SMM3000A80024C series delivers 2.25kW repetitive peak power to medical lasers with high efficiency. The SMM3000A80024C complies with medical safety standards and for silent operation it includes a thermo-controlled cooling system.

福建快3计划Laser equipment is widely used in medical applications and from cosmetic through to general surgery they all require power supplies able to deliver very high peak energy levels to the laser or discharge tubes. However, high peak energy and the repetition thereof generates electromagnetic radiation and line disturbance. This is a challenge for power designers who need power solutions that are able to deliver the required amount of power without generating line disturbances, whilst also guaranteeing patient and operator safety when high voltages and energy levels are involved during the process.

CO2 (carbon dioxide) lasers or Erbium YAG are commonly used in medical applications, though the energy released during the pulse related to the specific task can vary by large amounts. There are different types of pulsing for CO2 lasers. In the cosmetic word, there is a newer technology called UltraPulse (a very short pulse duration with high pulse power and very high influence), that is even faster than SuperPulse (medium pulse duration with medium pulse power).

“A good device has less than a millisecond pulse width, meaning that it is incredibly fast-firing, requiring the power supply to be able to deliver high energy levels during the pulse, but also able to restore energy for the next pulse。” Said Patrick Le Fèvre, Powerbox Chief Marketing and Communication officer。 “To meet such requirements is a great challenge, though by combining digital power and special PRBX innovations, the PRBX 2。25kW AC/DC capacitor charger SMM3000A80024C effectively meets the requirements of the job and complies with the medical safety standard IEC60601-1 3rd。

The power supply provides a level of protection, primary to secondary main output of 2xMOOP, and 2xMOPP to auxiliary output。 To accommodate different capacitor banks and applications, the output voltage can be adjusted from zero to 800VDC (600VDC nominal) with an output current of 5。5A at nominal。 An automatic current controller guarantees that the power envelope is always within safe limits, reducing capacitor aging and overstressing of components, thus contributing to a longer lifetime。 The SMM3000A80024C has a built-in microprocessor constantly monitoring the charging status, reporting end of charge and discharge level, as well as all protection warnings due to abnormal operation such as over-temperature, over-voltage and current。

To reduce line disturbances the SMM3000A80024C includes a very high efficiency power factor corrector (PFC), soft-start circuitry, filtering and is housed in a six-sided shielded case。 To limit audible noise to a minimum, the SMM3000A80024C’s fans are thermo-controlled, regulating their speed to the minimum required for normal, safe operation。 The SMM3000A80024C also delivers an auxiliary output voltage of 24VDC, reducing the need for an additional power supply to power laser controller and interfaces。 For additional power, the SMM3000A80024C can be connected in parallel。

PSMA Publishes Technology Report: 3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies
Posted: 2018-9-6
Comprehensive report is the first to address higher power embeddable passives that will accelerate the development of higher density power sources using new, 3D disruptive packaging technologies

The Power Sources Manufacturers Association (PSMA) Packaging Committee announces the publication of its latest report titled, “3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies.” This is the third in a series of reports focused on using embedded substrate technology for building power sources. It is the first extensive study of embeddable passive components both available and in development for use in the power path of power sources. The report contains extensive research and product illustrations geared to an audience of technology executives and design engineers.

Miniaturization of passive components without compromising their power handling and efficiency and their integration with actives has always been a key focus for power packaging. There is also an increasing trend to vertical or 3D package integration to address the performance issues by eliminating parasitics from interconnections. Embedding gives lowest package inductance and enables co-integration of power systems and drivers in a single package with direct interconnection between gate driver circuits and switches with shortest interconnection length. This has become even more important with the rapid emergence of wide bandgap power switching devices. This, however, leads to several process integration and reliability challenges that need to be systematically addressed.

福建快3计划Georgia Tech Packaging Research Center, under contract from PSMA systematically surveyed the recent advances in passives, active embedding and 3D passive-active integration to generate this report, with emphasis on 3D power packaging enabled by advances in passive components and embedding of actives in power packages。 A detailed literature study was conducted on key advances in embedded passive technologies and related topics。 Emerging nanomaterials, processes and technologies are described in detail for inductors, capacitors and resistors。 Nanostructured materials provide additional degrees of freedoms in enhancing the properties to improve the performance metrics such as volumetric density and efficiency of the components。 Key enabling building-blocks are described for each technology。 The manufacturing challenges are also highlighted in advancing the components to improve performance。 Industry leaders were surveyed to get the recent technology advances in each category。 Roadmaps are projected for passive component advances and active embedding technologies。

The trends and roadmaps in 3D power packaging are also described in three categories: low power (1-100 W), medium power (100-1000 W) and high power (10-100 kW). Integration in each category is classified into lead-frame-based, substrate-embedding based and traditional ceramic substrates. Active embedding with panel-scale substrate manufacturing is also reviewed in detail. Recent innovations in substrate materials and associated reliability challenges such as via cracking, dielectric cracking or electric breakdown are highlighted. Advances in die-attach solutions with sintered nanocopper are reviewed, highlighting the evolution of low-stress sintered copper-based die-attach solutions.

Co-chairs of the PSMA Packaging Committee, Ernie Parker of Crane Aerospace & Electronics and Brian Narveson of Narveson Consulting, described the report as “the first comprehensive document to discuss the challenges companies will face to implement embedded passives in 3D power packaging to create the significantly higher power densities。

The PSMA report on 3D packaging was provided free of charge to PSMA Regular and Associate Company members.  Additional copies may be purchased at the member price of $290. PSMA Affiliate members may also purchase the report for $290. The report is available to non-members for purchase on the PSMA website (www.abituku.com/publications) for the price of $3,490.
