Abstract :
During the inversion process of an SPWM inverter, it is very important to obtain the moments of a power switch. The magnitude of the harmonic waves can be diminished by the good moments. In this paper, the new method of reducing the influence of all harmonic waves, which can obtain the optimal switching time by using genetic algorithms, is presented. Simulation results show that this method can suppress effectively low-order harmonic wave with the limited items
