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 such as dV/dt (dU/dt), overshoot, and common mode noise. Pre-Switch estimates that

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-resonance voltage waveform, timed accurately to enable zero voltage switching. Th

This white paper offers a discussion of the power electronics market, the dynamics that have driven it for over thirty years, and the quest to reliably and economically reduce switching and conduction losses. Ever more innovative topologies and semiconductor materials, like the newest generation of silicon IGBTs and MOSFET trench designs and faster SiC and GaN MOSFETs have been used to bring switching times down, but the resulting levels of dV/dt and EMI are a major roadblock
