Silicon Valley, October 30, 2019: WBGS (WBGlobalSemi, Inc.) announces filing of provisional US patent for High Pulse Energy Modular Inductor (HPEMI) for use in research, product development, and fabrication testing of Wide Band Gap Silicon Carbide (SiC) semiconductors, power modules, and products.
Bruce Carsten, CTO of Power Converters, stated, "We think this provisional patent encompasses a high value testing and measurement instrument that will enable engineers, scientists, and lab and fab technicians to directly measure the exact voltage, current, on switching loss, off switching loss, frequency, and avalanche breakdown of semiconductors, power modules, and products from 1,000 Volts to 50,000 Volts and 150 Amps to 2,400 Amps by adding modules to the HPEMI test instrument.
The HPEMI has the smallest footprint and highest energy concentration enabled by current materials resulting in a very small form factor per module.
One module can measure up to 3,000 Volts and 150 Amps which is adequate for many uses addressing the existing renewable energy and emerging electrical vehicle market. Our VP International Business recently visited China and Japan and it seems that 100+ companies plan to play in the 1 kV, 1.2 kV, and 1.7 kV SiC domain, with 3.3 kV emerging in the next several years, followed by adoption of 6.5 kV and then 10 kV for heavy e-transport, fast chargers, microgrids, and smart grids. One modular, scalable, reconfigurable test platform, where the user can buy a base system and add modules as needed, seems a better solution than buying or building multiple single use instruments.
Initially I designed the HPEMI for in-house use so we can measure a wide range of semiconductors, power modules, and products, however with the grown of the SiC market from $10 million to $1 billion in the past decade and anticipated growth to $10 billion by 2030 we think a number of research labs, product development labs, and fabrication & manufacturing facilities can benefit from using a HPEMI."
