Abstract:A novel three phase uncontrollable rectifier three phase converter inverter is proposed, accordingly, a novel reconstruction SPWM technology that can greatly eliminate harmonics in inverter's output voltage is also presented. The performance of the new inverter source using new PWM technology is compared with the traditional inverter source by simulation and experiment. It is obvious that the new inverter source and the new PWM technology will be in wide use in the foreseeable future.
Keywords:inverter  small DC capacitor  SPWM
