Programmable Power now up to 7.5 kW and 1500 V

Genesys plus 7.5kW programmable power supply
Higher voltages are now available in the Genesys+ programmable power supply range beyond the standard offered in the 5 kW series, with outputs from 0 to 20 V at 375 A, through to 0 to 1,500 V at 5 A.

The new very high power density 7.5 kW rated 1U models enable system configurators to avoid the need to parallel lower wattage power supplies, saving space in the rack or cabinet.

Genesys plus 7.5kW programmable power supply

91 to 92% efficiency

With energy costs rising, efficiency is becoming increasingly important in choosing your benchtop power supplies. The Genesys+ range offers efficiencies of 91-92%.

The power supplies benefit from DSP (Digital Signal Processing) technology and the latest generation components, including ferrite materials, to obtain these high efficiencies. Less internal waste heat ensures a higher power rating without compromising reliability.

Achieving 7.5 kW of power

For additional power, the 7,500 W power supplies use TDK-Lambda’s advanced parallel system (patent pending) allowing a multiple unit system to achieve a dynamic response and ripple and noise performance comparable to that of a single power supply.

15 kW of power can now be delivered in a 2U rack mount height rather than a 3U. This space-saving capability is important for any power supply application.

Applications including automotive testing

The 7.5 kW power supplies are ideal for:

  • automotive testing – including electric and hybrid cars
  • general test or research
  • measurement
  • semiconductor fabrication
  • battery manufacturing
  • inverter testing

PPM Power leads UK supply chain project to deliver Next Generation Power Converters

PPM Power is leading a consortium of UK companies to develop a supply chain for power systems based on embedded Gallium Nitride (GaN) devices.  The project is funded by Driving the Electric Revolution, an ISCF Challenge delivered by UK Research and Innovation.

The consortium includes: RAM Innovations, Camutronics, TTPi and the Compound Semiconductor Applications Catapult.

Known as “P3EP” (Pre-packaged Power Devices for PCB Embedded Power Electronics) the project will leverage the performance advantages of Gallium Nitride (GaN) while delivering practical solutions that meet the integration and scalability needs of the industrial, automotive and aerospace industries.

The new supply chain will allow PEMD (Power Electronics, Machines & Drives) manufacturers to build converters with the highest power densities and allow UK power semiconductor companies to enter these markets.

Project lead, Joe Petrie – Strategic Marketing Manager at PPM Power – explained: “We are reducing power converters in size and weight by up to 10x compared to existing silicon-based designs. That has a big impact potential for applications such as automotive power management, the electrification of aerospace, and industrial applications such as motor drives and the power systems for robotics.”

Aeroplane and GANEmbedded GAN promises to reduce the weight of power converters by up to 90%; making it an ideal technology for aerospace

Phil Surman, PPM Power Sales Director, said: “PPM Power is bringing the widest view possible of the high performance power electronics market; interpreting end user requirements and delivering insights that will enable the project to impact as quickly as possible.”

The project will last for 34 months.

 

Project Objectives

Industry drive for more efficiency, smaller size and lower weight products means sectors such as automotive, aerospace and industrial can benefit from module-based solutions that can be used in existing production lines and are available in volume.

The P3EP project is helping to meet the needs of OEMs and systems integrators by enabling a reliable, robust supply chain of leading-edge, wide-band-gap semiconductor-based power modules that can be ramped up to production level quantities.

Based on embedding pre-packages, the supply chain will enable more compact and lightweight power conversion modules that draw on the very high switching speeds and increased efficiencies that GaN can deliver.  Power conversion modules that are up to 10x smaller than those using conventional silicon transistors become possible.

The potential of GaN to boost conversion efficiencies and increase power densities is widely acknowledged.  The P3EP project allows PEMD manufacturers to leverage the radical advantages of embedded GaN without having to become experts in embedding technology and processes.

 

The benefits of embedding GAN

The project will overcome limitations caused by existing packaging supply chains. By avoiding the use of conventional packages with wire bonds, parasitic losses are drastically reduced. Bond wires cause stray inductances and capacitances and increase losses. Dissipation of heat will be improved, thus leading to greater operational reliability.

Embedded GaN pre-packages enable 3D integration which further improves design compactness; supporting faster switching, lower losses and efficient heat extraction as well as increased robustness.

What is Soft Punch Through IGBT Technology?

SPT IGBT forward characteristics

The latest Trench Fine Pattern (TFP) IGBT chips are built on the developments in Soft Punch Through (SPT) chip design, delivering the lowest losses ever for IGBT switches. The progression of this technology is leading the way to a better IGBT.

SPT Technology

SPT technology features thinner silicon, combined with a highly-rugged planar cell-design platform. The technology substantially increases the cell latch-up immunity, achieving lower losses. IGBT and diode chips with SPT planar technology therefore have higher switching performance and reliability.

SPT+ and SPT++ Technology

IGBTs using Hitachi Energy’s advanced SPT+ technology benefit from a conduction loss reduction of 20 to 30% compared to earlier SPT technology.

Figure 1 shows the basic difference between SPT+ and SPT++. By introducing an N-enhancement layer surrounding the channel-P-well, the plasma concentration is improved on the emitter side, lowering the on-state losses. The introduction of the SPT++ allowed the N-enhancement layer profile to be optimised further with the main goal to make another step in conduction loss improvement. Together with thinner silicon, a reduction in VCE SAT of half a volt was possible.

Soft punch through planar profile

Figure 1 SPT+ planar IGBT enhanced carrier profile

Hitachi Energy’s SPT+ IGBT technology permitted the company to establish a new technology curve benchmark over the whole IGBT voltage range from 1200 V to 6500 V.

SPT technology VCE SAT

Figure 2 Vce sat for different IGBT cell technologies on SPT silicon at 125 °C

IGBT Characteristics and Losses

Figure 3 shows the on-state curves of the 6.5 kV SPT+ IGBT. The typical on-state voltage drop (VCE,on) at nominal current and Tj =125 °C is 4.0 V. The SPT+ IGBT shows a positive temperature coefficient of VCE,on, already starting at low currents. This enables a good current sharing capability between the individual chips in the module.

SPT IGBT forward characteristics

Figure 3 Forward characteristics of the 6.5 kV SPT+ IGBT

Figure 4 shows the turn-off waveforms of the 6.5 kV HiPak module measured under nominal conditions ie, at 750 A and 3600 V. Under these conditions, the fully integrated turn-off losses of the module amount to 5.2 J.

SPT IGBT turn-off waveforms

Figure 4 6.5 kV SPT+ IGBT turn-off under nominal conditions measured at module level

TFP Technology

IGBT chips based on a Trench Fine Pattern (TFP) technology build on the SPT++ N-enhancement technology by adding a very compact fine patterned trench cell to improve the conduction and switching losses by more than 30% compared to the SPT++ technology.

Hitachi Energy’s range of SPT+, SPT++ and TFP IGBT and diode chips is available at 1200 and 1700 V, ranging from 50 to 300 A. Contact us to find out more about Soft Punch Through technology and discuss your requirements.
