摘要：

This paper proposes a novel control strategy for electrolytic capacitor-less quasi-Z-source inverter, which fed adjustable-speed drive (ASD) system with almost unit input power factor. The system has no shoot through issues and gains high reliability. By using E-caps-less topology, the life time can be greatly increased. In order to guarantee the high power factor and the ability of resisting grid voltage sags, the voltage and current double closed loop structure is used to control the QZSI. Choose PMSM driving system as the control object, a new control strategy is adopted to improve the power factor further. The effectiveness of the proposed system has been verified by simulation.
