Pre-Switch, the company who developed AI-based forced-resonant, soft-switching technology enabling efficient DC/AC, AC/DC inverters running at 100kHz and above, has added the ability to reprogram its Pre-Flex soft-switching motor/inverter SoC, enabling products in development or in the field to be updated to give even higher performance.

Pre-Switch, the company that has developed the AI-based forced-resonant, soft-switching technology enabling efficient DC/AC, AC/DC inverters running at 100kHz, has appointed Jacek Borecki as Chief Technology Officer.

Pre-Switch has announced new data proving the efficiency of the company’s architecture at low load as well as full load.

Pre-Switch has published performance data that shows that its 200kW (space vector modulated) CleanWave200 evaluation inverter exceeds 99.3% at 100kHz using only three discrete, low cost 35 mΩ SiC MOSFETs per switch location.  This is expected to revolutionise EV and renewable energy designs.

Pre-Switch has announced Andre Willis as VP of Engineering. Previously a founder of HiQ Solar, the designers and developers of award-winning SiC inverter solutions, Willis is an inventor and creator with over 30 years power design experience.

Pre-Switch has released first test data from its Cleanwave 200kW inverter reference. Double pulse test data demonstrates that the Pre-Switch soft-switching platform - comprising the Pre-Drive3 controller board powered by the Pre-Flex FPGA, and RPG gate driver board - reduces total system switching losses by 90% or more.

Pre-Switch has announced that its soft-switching IGBT and silicon carbide gate driver architecture, including the Pre-Drive3 controller board, powered by the Pre-Flex FPGA, and RPG gate driver board, can reduce the cost of solar inverters. The two-stage architecture delivers the same switching loss performance as a five-level design, resulting in reduced cost, control complexity and BOM count. 

The Silicon Valley start-up that is delivering soft switching for DC/AC and AC/DC power conversion, Pre-Switch, has announced its CleanWave 200kW silicon carbide (SiC) automotive inverter evaluation system that enables power design engineers to investigate the accuracy of the company’s soft switching architecture and platform over varying load, temperature, device tolerance and degradation conditions.

  AI can be used to implement soft switching and minimise power conversion switching losses, argue Derek Kroes and Bruce Renouard, Pre-Switch

Pre-Switch, a Silicon Valley start-up that emerged from stealth mode last year, has expanded its revolutionary soft-switching IGBT and silicon carbide gate driver architecture to cover 3-phase power systems. The platform, including the Pre-Drive3 controller board, powered by the Pre-Flex FPGA, and RPG gate driver board, enables a doubling of power output for a typical inverter, or an increase in switching speed by a factor of up to 20 times.
