一种三相隔离双向AC/DC变换器及其改进的SVPWM算法

This paper proposes a three-phase isolated bidirectional ac/dc converter. The converter achieves buck-boost ac/dc bidirectional conversion, sinusoidal ac current, and high-frequency electrical isolation with single-stage structure. The traditional SVPWM algorithm should be modified to keep the voltage-second balance of the transformer. The circuit derivation, operation principles, and SVPWM algori...
