6 kW High Voltage DC-DC Converter for EV Charging based on STMicroelectronics Solution

The STDES-6KWHVDCDC reference design is a 6 kW high voltage DC-DC converter mainly for battery charging in an EV infrastructure. The reference design consists of a full bridge LLC resonant converter, digitally controlled. For the output rectification, SiC diodes have been used. Depending on the output voltage requirement, the LLC transformer output configuration is interchangeable between center tapped and full-wave. This results in frequency fold-back that increases efficiency by a wide margin over an entire output voltage range.
