In addition to the disruption to the power industry brought about by wide-bandgap semiconductors and other component technology, there is also rapid development in software-based power solutions as well. Recently at APEC, Pre-Switch promised to unveil their latest power solution at PCIM, and had their CleanWave 200kW silicon carbide (SiC) automotive inverter evaluation system on display there, as promised.

We talked to Pre-Switch CEO Bruce Renouard on the new platform, which enables power design engineers to investigate the company’s soft-switching architecture and platform. Made up of the Pre-Drive3 controller board, Pre-Flex FPGA, and RPG gate driver board, the CleanWave inverter evaluation system uses Artificial Intelligence (AI) to constantly adjust the relative timing of elements within the switching system, to force a resonance to offset the current and voltage waveforms, minimizing switching losses in the power conversion system.
