Abstract :
The multiple overlap mode of the overlap carrier wave phase shift PWM (SVPWM) inverter is one of the development directions of the super-high capacity inverter, this paper reasons the relation between carrier wave phase shift SVPWM circuit output voltage and phase shift angle, put forward the best phase shift angle formula, proposed two kinds of control schemes and compares them. Through the experiment of surface to air missile 60 kVA static transducer, It is testified that adjusting the pulse- width of inverter step by step is also an executable method through the suitable design of output filter.
