Effect of gate pulse variation on the performance of fifteen-level cascaded H-bridge voltage source inverter

This paper proposes a fifteen level H-Bridge cascaded multilevel inverter with fundamental frequency switching for low power applications such as solar powered power supplies, battery powered standby power supplies. The effect of the variation of gate pulse on the performance of the inverter for different conditions of gate pulse variation is studied and simulation results are presented. Experimental implementation of gate pulse generation on a low cost FPGA is presented. The results presented in this paper are useful in designing the inverter, determining the control range of the inverter for the reliable and stable closed loop and fault tolerant operation of the inverter.
