CleanWave200 evaluation system, 600V DC input, 2000 microseconds continuous running,10kHz Fsw, 3 parallel SiC MOSFETs per switch location. PWM input is varied to produce a ramp to simulate the first part of a sine wave output.

The following is a series of 20 single microsecond transition screen captures over a 2000 microsecond period of continuous operation of the CleanWave200 evaluation system.  T...

This paper details the workings of the Auxiliary Resonant Commutated Pole (ARCP) forced resonant soft-switching architecture, which is now commercially valuable because of the advent of Pre-Switch’s AI-based control technology, Pre-Flex™. This article also briefly discusses how Pre-Switch technology can be used to improve electrical motor efficiency and solve significant motor design challenges su...

 Alix Paultre of Embedded Computing Design visits Pre-Switch and gets the live demo of forced-resonant soft-switching.

This unrehearsed video shows Pre-Switch's James Hamond (CTO) and Derek Kroes (VP Engineering) demonstrating a 10KW full bridge solar inverter running Pre-Switch's AI forced-resonant soft-switching technology (Pre-Flex). Pre-Flex uses a learning AI to predict and generate a forced-r...
