The STEVAL-11BID1KCB is an 11kW bidirectional battery charger and represents a complete solution for high voltage charging in both the industrial and automotive fields.
The board uses two control boards for the PFC and dc-dc stages respectively. The control board is based on the STM32G474RE microcontroller. The PFC stage operating frequency is 70 kHz. The dc-dc stage is operating at a fixed switching frequency of 100 kHz. A peak system efficiency of 96% was achieved for the design.
