摘要：

This paper presents a three-phase Embedded Switched-Capacitor Z-Source Inverter (ESC-ZSI) topology with continuous input currents. In the proposed ESC-ZSI, the continuous input currents can be achieved by embedding the dc sources into the symmetrical impedance network compared with a Modified Switched-Capacitor Z-source Inverter (MSC-ZSI). A detailed operation principle analysis of the proposed topology is introduced. Moreover, the boost ratio, the voltage gain and the voltage stresses of the power switch and capacitors are carried out to highlight the advantages of the proposed topology as compared with the conventional topologies. Finally, simulation and experimental results are provided to validate the theoretical analysis.
