Abstract

Voltage waveform of single inverter contains more harmonics. In order to reduce the harmonic content, the H-bridge inverter with multiple structures was used to obtain a low harmonic voltage. However, this paper explored the multiple method based on the neutral point clamped inverter for obtaining the multiple circuit with lower harmonic content than the H-bridge multiple structure circuit. Further, it analyzed the advantages of output voltage waveform and harmonic suppression shown in an improved multiple structure inverter. Simulation waveforms confirmed the reliability of the theoretical analysis, proving that this method can obtain the ideal voltage waveform and reduce harmonics.
