Abstract
The PWM control technique is proposed which can eliminate the harmonic components of the nonsinusoidal ac line current such as the current of 6-phase rectifier by injecting PWM current. TSC(Time-Sharing Control) is adopted to avoid the unbalance between three PWM injection currents at the three-phase system. Also a new power circuit for three-phase filter is suggested for realizing the proposed PWM control technique. The operation characteristics are investigated theoretically and experimentally to show the feasibility of the optimized injection method.
