Abstract Dead-time will affect the quality of the inverter output waveform, so the conventional three-phase inverter control strategy without dead-time has some limitations. This paper proposes a novel three-phase inverter control strategy based on the principle of no dead-time control strategy. A particular combination of space vector is adopted to eliminate dead-time according to the load impedance angle characteristics. Then the immune algorithm can optimize the time and the order of space vector, so as to minimize the total harmonic distortion (THD) rate of the inverter output waveform and improve the fundamental voltage value. Furthermore, the platform was established for a small capacity simulation experiment. The results show that the IA-based optimal SVPWM control scheme can not only effectively and safely eliminate the effects of dead time, but also significantly reduce the THD of output waveforms and the fundamental voltage value.
