Abstract
Diode rectifier has many low order harmonics in line currents. So, power factor of input side is relatively low. Recently, PWM conveters have been actively studied in order to reduce the harmonics. This paper describes a voltage source PWM rectifier with feed-forward compensation of instantaneous load power. By adding feed-forward compensation to dc link voltage control loop, the fluctuation of dc link voltage at a sudden load change can be considerably suppressed. Simulation based on analytical approach Was performed and the results of it showed a good agreement with theory.
