摘要
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).
