| Abstract: | The control scheme of multilever high_power invertering power supply is analyzed,a novel control scheme suitable for high_power invertering power supply is proposed. The proposed control scheme incorporates dual SPWM technique using in single power cell of multi_overlaping power cells technique. Thank to this scheme,the losses of the power devices are reduced,the output waveforms are improved,and the harmonics distort of the output waveforms are reduced. Some simulation on this scheme are performed. Experiment proved the correctness of this control scheme and the simulating results. |
