POWER FACTOR CORRECTION OF THREE PHASE AC-DC CONVERTER VIA CURRENT CONTROLLER AND PWM TECHNIQUE
Use of three phase AC-DC converters for DC loads can cause high harmonics on the AC side, reducing power factor. To improve the power factor can not be done by adding a passive filter on the input side of the conveter. This paper proposes the improvement of power factor through the regulation of current on the AC side and the PWM technique. The current control method uses PI and the exact PWM technique is SVPWM. The System behavior and power factor observations are studied through simulations.
