Abstract
A new Z-source inverter called Quasi switched inductor Z-source inverter(QSLZSI) is presented in this paper. The proposed inverter not only inherits the advantages of traditional Z-source inverters but also has the unique features of capacitor H-bridge circuit: simplified structure, reduced component count, simplified control strategies, higher boost factor. The operating principles of the proposed inverter are described, and a circuit analysis is provided. This new inverter is especially suitable for renewable energy and the variable-frequency adjusting speed of the motor servo system. This paper presents the simulation results of QSLZSI and compares them with those of the SLZSI and LZSI in detail. Laboratory prototypes are constructed. Experimental results confirm the theoretical analysis.
