Year: 2018

Type: article

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.
