Research on Key Technologies of high power DC charging module

Abstract

This paper mainly studies a high-power DC charging module with output voltage range of DC 200V to DC 1000V, and can realize constant power 40kW output in the range of DC 300V to DC 1000V, which realizes the advantages of high efficiency, high power factor and high power density, meets the high-voltage platform electric vehicle and supports the development route of “Chaoji” fast charging. This paper mainly studies the hardware topology platform of high-power ultra wide voltage range and ultra wide constant power DC charging converter and the software control strategy platform of high-power DC charging converter.
