This document discusses a proposed inductor type Z-source inverter with third harmonic injection control method. The proposed inverter eliminates capacitors from the traditional Z-source inverter circuit to avoid large inrush currents. It contains two inductors and three diodes instead. Third harmonic injection control is also proposed to further reduce total harmonic distortion and losses compared to traditional Z-source inverters. Simulation results show the proposed inverter produces three-phase output voltages of 700V and currents of 10A from an input of 230V DC. Harmonic analysis confirms the third harmonic injection control reduces harmonic levels as the number of cycles increases.
