Wolfspeed’s new SiC power module is built for harsh environments

Wolfspeed, a specialist in silicon carbide (SiC) power products, has released a new power module that’s designed to withstand high-humidity, high-temperature and high-voltage conditions. The new all-SiC module, rated for 300 A and 1.2 kV blocking, passed a reliability test that subjected it to an environment of 85% relative humidity and 85° C ambient temperature… Read more »

EV tech explained: What are the limiting factors of an EV’s regenerative braking force?

In many EVs, regenerative braking is limited by the manufacturer to a modest level, and usually offers little or no ability for the driver to adjust it (aside from the few cases in which regen is made proportional to the initial movement of the brake pedal). Is tepid regen braking the result of some sort… Read more »

Tesla’s chief motor engineer discusses the potential of next-generation motor technologies

Tesla spends a considerable amount of resources on basic research into EV systems – as well it should. EV technology is very young compared to that of ICE vehicles, so it’s safe to assume that, in a few short years, the aggregate of many incremental technology advances could lead to significantly better EVs. Of course,… Read more »

Mitsubishi Electric develops ultra-compact SiC inverter for hybrids

Mitsubishi Electric has developed a working model of an ultra-compact silicon carbide (SiC) inverter for hybrid vehicles. The company believes it to be the world’s smallest SiC of its type, with a volume of only 5 liters. Mitsubishi also claims that the new inverter offers the world’s highest power density for two-motor hybrids: 86 kVA/L,… Read more »

Wolfspeed launches a new silicon carbide MOSFET for EV inverters

Wide Bandgap (WBG) semiconductor technologies have attracted a lot of attention and research funding in the past decade. Both public and private institutions around the world have been obsessed with accelerating the evolution of WBG tech into commercial power electronics applications. What’s all the fuss about? WBG materials such as silicon carbide (SiC) and gallium… Read more »

ARPA-E to award up to $20 million for wide bandgap power electronics

The acronym-loving officials of ARPA-E have established a new program called Creating Innovative and Reliable Circuits Using Inventive Topologies and Semiconductors (CIRCUITS), which will award up to $20 million to develop a new class of efficient, lightweight, and reliable power converters based on wide bandgap (WBG) semiconductors (DE-FOA-0001727).
