A Single-Phase Cascaded H-bridge Quasi Switched Boost Inverter for Renewable Energy Sources Applications

Abstract—Recently, multilevel inverters have become more attractive for researchers due to low total harmonic distortion (THD) in the output voltage and low electromagnetic interference (EMI). This paper proposes a single-phase cascaded H-bridge quasi switched boost inverter (CHB-qSBI) for renewable energy sources applications. The proposed inverter has the advantage over the cascaded H-bridge quasi-Z-source inverter (CHB-qZSI) in reducing two capacitors and two inductors. As a result, cost, weight and size are reduced. Furthermore, the dc-link voltage of each module is controlled by individual shoot-through duty cycle to get the same values. Therefore, the proposed inverter solves the imbalance problem of dc-link voltage in traditional CHB inverter. This paper shows the operating principles and analysis of the single-phase cascaded H-bridge quasi switched boost inverter. Also, A control strategy for the proposed inverter is shown. Experimental and Simulation results are shown to verify the operating principle of the proposed inverter.

Index Terms—Renewable energy sources, cascaded H-bridge inverter, quasi switched boost inverter, quasi Z-source inverer, shoot-through state, multilevel inverter.
