PFC Optimization Modulation Strategy for Bidirectional Resonant Converter of V2G Charging Station
摘要
Abstract
To improve the integration and performance of the bidirectional converter for electric vehicle bidirectional charging stations,a single-stage resonant three-port bidirectional converter with V2G,G2V and H2L modes is proposed.First,the equivalent model of the converter is established,and the mathematical model for the output power is derived.Then,the working modes of the converter are analyzed,and the resonant cavity current is designed.An optimized modulation strategy is proposed that balances low current stress and power factor correction(PFC)on the grid side.Finally,simulation analysis is conducted under PLECS.The results show that the converter achieves a high power factor on the grid side under both forward and reverse operating conditions while maintaining low current stress.The proposed optimization modulation strategy helps to improve the converter's efficiency and the utilization rate of electrical energy in the power supply lines.关键词
