摘要：This paper proposes a three phase five-level inverter which uses a single DC (PV) source, unlike a conventional cascaded H-bridge (CHB) which requires multiple DC (PV) sources, and also a novel Selective Harmonic Elimination Pulse Width Modulation (SHE-PWM) for reduced voltage Total Harmonic Distortion (THD) compared to a conventional SHE-PWM. The proposed inverter uses reduced number of switches when compared to conventional inverter. The proposed three phase inverter is simulated in MATLAB with both conventional and new SHE-PWM techniques. The simulated waveforms of the line, phase voltages and load current are studied in detail. A comparison of THD values is for both conventional and proposed SHE-PWM is presented. This is followed by the hardware implementation of the proposed inverter with the new SHE-PWM, and the results for line, phase voltages and the load currents are again reviewed. The hardware results are found to match the simulation results. The results confirm that the proposed SHE-PWM has the ability to deliver a reduced THD when compared to a conventional SHE-PWM.
