Abstract
This paper proposes a novel single-phase quasi-Z-source AC/AC converter (qZSAC). Compared to traditional single-phase Z-source AC/AC converter, the proposed qZSAC has following features: the input voltage and output voltage is sharing the same ground; the operation is in continuous current mode (CCM). The proposed qZSAC can control to shape the input current to be sinusoidal and in phase with the input voltage. The operating principles, simulation results are presented. To verify these described performance features, PSIM simulation and experimental results were performed with a low total harmonic distortion of input current and high input power factor.
