Based on the analysis of the three-phase SVPWM technique. A single-phase voltage vector space and a plane coordinate rotating transform were introduced. Then, a single-phase SVPWM technique and its realization method were put forward. Finally, the validity of single-phase SVPWM technique was proved from the experiment. And the result proved that not only the SVPWM inverter control algorthm can be applied to single-phase PWM inverter, but also the optimal switching SVPWM technique deduced from three-phase SVPWM technique could be applied to the single-phase inverter.
