Pre-Switch reports 99.3% efficiency for 200kW inverter at 100kHz

Pre-Switch Inc of Campbell, CA, USA, a start-up that has developed the first AI-based DC/AC, AC/DC soft-switching controller, has published performance data that shows that its 200kW (space vector modulated) CleanWave200 evaluation inverter exceeds 99.3% efficiency at 100kHz using only three discrete, low-cost 35mΩ silicon carbide (SiC) MOSFETs per switch location. This is expected to revolutionize electric vehicle (EV) and renewable energy designs…
