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.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.
Features
PFC stage 3-phase, 2-level bidirectional AC-DC power converter:Rated nominal AC voltage: 400 VAC at 50 HzRated nominal DC voltage: 800 VDCNominal power: 11 kWRectifier mode: power factor: PF >0.99, inrush current control and soft startupInverter mode: active and reactive power control, integrated grid connection solutionDC-DC stage dual active bridge (DAB) power converter:Nominal DC input voltage 800 VNominal DC output voltage 550 to 850 VDAB: switching frequency 100 kHzPower section based on SiC power modules:ACEPACK DMT-32 power module for high integration levelHigh frequency operation for weight and size reductionBidirectional capabilitiesDAB soft switching behavior enabled by enhanced modulation techniques management
