一种新型四端口三相DC-AC变换器系列及其基于载波的PWM策略

A novel family of four-port three-phase dc–ac converter (FPTPC) topology is proposed in this article, which has two dc ports and two three-phase ac ports. It can be combined with dc–dc to form the quasi-single-stage FPTPC whose low voltage dc port voltage can be varied over a wide range. The proposed four-port three-phase dc–ac converter topology is first described. Then, its differences with T-ty...
