Previously, Borecki was the senior inverter designer at Audi Sports, based in Germany, working on Audi’s performance EV race team.
Bruce Renouard, Pre-Switch CEO comments: “It’s great news for Pre-Switch that Jacek has chosen to relocate to the USA to join the Pre-Switch team. Jacek is a strong proponent of soft-switching and our forced-resonance architecture, and he has already made vital contributions to our programme.”
Adds Borecki: “During my time at Audi I became convinced that all future EV inverters will need to use soft-switching in order to achieve the high efficiencies required. Therefore, it is very exciting for me to join Pre-Switch as they commercialize this technology for the first time anywhere in the world.”
The Pre-Switch technology delivers many benefits including industry-leading inverter efficiency at all load points (low load, average, peak), and improved motor efficiency and reliability. Fewer SiC/IGBT transistors are required for a given power output, and DC link capacitor size and cost can be reduced. Also, low-cost discrete transistors can be used to replace heavy expensive power modules.
Pre-Switch technology is proven, and evaluations systems are available.
