一种用于交流-交流功率转换的双功率路径混合变换器系列

The traditional ac–dc–ac power conversion has two power conversion stages and low efficiency. In order to improve the system efficiency, the direct-type ac–ac chopper and two-stage ac–dc–ac converter are combined to construct a family of dual power path ac–ac hybrid converter (DPPAC) topology under the guidance of partial power conversion. Taking the basic ac–ac chopper as an example, the system a...
