Product overview
Description
The STDES-BCBIDIR is an 11 kW bidirectional battery charger and represents a complete solution for high voltage charging in both the industrial and automotive fields.
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 structure of the DC-DC section can be configured in DAB or CLLC topologies thanks to the external connection of the resonant cell.
Both stages are based on the ACEPACK DMT-32 SiC power module. The solution 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 fixed switching frequency (100kHz) or variable switching frequency (82 to 235 kHz), respectively in DAB or CLLC topology.
A system peak efficiency greater than 96% was achieved for the design in direct mode.
