Study on the Z-Source Inverter with Low Voltage Stress

Abstract:

This paper proposed a kind of low voltage stress Z-source inverter topology. In the topology, the inductors of Z-source can be connected alternatively in parallel during the time of shoot-through and in series during the other time. Thus the network can obtain a high boost factor with a small shoot-through duty ratio and can decrease the voltage stress across the switch divices greatly. The principle of the topology was analyzed in detail and the simulation experiments was made as well. Simulation results verified the validity of the topology.
