Abstract :
In this paper, the structure of the multilevel invertor of multilevel invertor´s circuit is analyzed based on ladder-wave PWM principle and waveform theory, and a method of switching angle control is proposed. The specified lower frequency harmonics is eliminated and the fundamental voltage is adjusted by controlling the switching time of power switches. The control strategy on PSPICES Simulation is designed and the results show that the value and frequece of the output voltage is adjustable.
