Embedded Computing Design: Pre-Switch Demo in the Lab-Pre-Switch demonstrates their forced-switching AI power technology

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. The demonstration shows discrete IGBTs running at 50Khz at 98.5% efficiency, inverting 320Vdc to 240Vac. Able to work for both IGBT's and wide-bandgap devices, Pre-Flex enables switching losses to be reduced from 80% (IGBT), and 95% (wide-bandgap) enabling up to a 5X to 20X faster Fsw when compared to hard-switched legacy solutions.

Measuring the Plant Transfer Function of ​a Digitally Controlled Converter-Dr. Ali Shirsavar

Measuring the plant of a digitally controlled converter is not as straightforward as in the analog case. The solution however is quite simple. Set the compensator to a constant value and measure the loop. Dr. Ali Shirsavar explains the details and how to connect the Bode 100 to perform the measurement.
