    Abstract: PURPOSE: A hybrid PWM(Pulse Width Modulation) AC/DC converter having an active filtering function in a power supply system is provided to convert an AC voltage to a DC voltage and remove harmonic current by using an active power filter function. CONSTITUTION: The current(Isa,Isb,Isc) generated from power source(103) is the sum of the current(ILa,ILb,ILc) consumed in a non-linear load(102) and the current(IFa,IFb,IFc) inputted into a hybrid PWM AC/DC converter(400). The current(Isa,Isb,Isc) of the power source(103) becomes sinusoidal wave by removing harmonic current from the current(ILa,ILb,ILc) of the non-linear load(102). The hybrid PWM AC/DC converter(400) is formed with an inductor filter(401), a capacitor filter(402), a pulse width converter power stack(403), and an inductor filter(404). The inductor filter(401) is formed with a plurality of inductors(LF1,LF2,LF3).

The AC-AC alternative voltage controller used to drop the power supplier voltage is connected to the three phase power supplier by Y-connection or delta-connection and shifts the phase by 30°. The phase of the dropped voltage is shifted by 180° by shifting the phase with 150° at the primary side of the transformer. The sum of the power source voltage used to drive the motor at steady state and the output voltage of the AC-AC alternative voltage controller used to vary the motor speed is supplied to the motor. At the initial operation stage, the AC-AC alternative voltage controller is turned off to prevent the initial overcurrent by forming the transformers as series connected inductors.
