Abstract

This paper presents the analysis of dynamic response of the ZVS Z-source rectifier and design of the closed-loop controllers for both the z-source rectifier and the z-network circuit. Due to the unique Z-network, the transient response is found to be challenging in controlling the ZVS Z-source rectifier. By combining the traditional PWM rectifier model and equivalent model of the z-network, The ZVS Z-Source rectifier model is proposed. Through detailed analysis, the controllers are designed to obtain the steady DC-link voltage and a sinusoidal AC voltage under linear loads
