High-Performance Bidirectional Fast EV Charger Featuring Full Power/Voltage Range and Cost-Effective Implementation

Fast chargers are a key element for transportation electrification. This paper proposed a fast charger topology able to comply with modern requirements in terms of bidirectionality and operation in the whole voltage range for 400 V and 800 V batteries at full power. The proposed architecture takes advantage of active filtering and partial power processing to achieve a cost-effective and efficient implementation. The proposed converter has been analyzed, simulated, and designed, and it will be tested using a 50-kW upwards-scalable module.
