Two Inputs FiveLevel QuasiZSource Inverter

This paper combines quasiZsource into a typical fivelevel inverter, which includes two dc voltage sources, two quasiZsources and five switching devices. In this structure, the output voltage amplitude is not limited to dc voltage source and it can be increased by quasiZsource. Besides, due to nature of Zsource families, this new structure is reliable and higher efficiency. Also, in this inverter, two quasiZnetworks can be controlled independently. This paper also proposes new switching algorithms for proposed fivelevel dual quasiZSource inverter based on pulse width modulation (PWM) and selective harmonic elimination method (SHEM) algorithms .The performance of proposed inverter and switching algorithm are validated with simulation results using MATLAB/SIMULINK software and experimental results based PCI1716 data acquisition system.
