Description

The STEVAL-11BID1KCB is an 11 kW bidirectional battery charger and represents a complete solution for high voltage charging in both the industrial and automotive fields.

STEVAL-11BID1KCB-IMAGE

It consists of two power stages: a PFC and an isolated DC-DC stage.

The PFC is based on a three-phase full-bridge topology.

The DC-DC section is Dual Active Bridge (DAB) topology.

Both stages are based on the ACEPACK DMT-32 SiC power module.

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.
