Abstract

This paper describes several PWM method for harmonics reduction in GTO inverter. The analysis and simulations of PWM techniques are carried out. The simulation results demonstrate that the programmed PWM methods(SHE PWM) are superior to the sine-modulated PWM method. The selected harmonic elimination (SHE) PWM scheme which eliminates specific lower order harmonics can generate high quality output waveform in PWM inverter.
