NOVI, Mich. - Dec. 1, 2020 - PRLog -- During November's China Automotive Supply Chain Summit, Preh was recognized  as a "Start of Production Excellence Supplier" for its innovative 800-volt DC voltage converter.

The series production of this DC/DC converter for an all-electric 800-volt sports car started in 2019.  As a multi-converter, the device combines three converters in one: the first component transforms 800 volts into 400 volts to supply the air-conditioning compressor. For roll stabilization, the voltage is then lowered to 48 volts and the power that is recaptured is converted back to 800 volts (bidirectional conversion). The remaining electrical consumption in the vehicle is supplied by the transformation to 12 volts.

Dr. Joachim Wagner, Head of Pre-Development E-Mobility at Preh, explains, "The success of this product is also based on the close co-operation between our development team and our engineers. They not only worked together very successfully in the development of the multi-converter, but also developed a high-voltage booster. This first-to-market solution allows vehicles with 800V batteries to be "refuelled" at any 400V fast-charging station. This is done by "boosting" from 400 to 800 volts with a capacity of up to 150 kilowatts."
