Abstract:
A power conversion controller having a novel power factor correction mechanism, including: a normalization unit, used to generate a normalized signal according to a line voltage by multiplying the line voltage with a normalizing gain, wherein the normalizing gain is proportional to the reciprocal of the amplitude of the line voltage; a reference current generation unit, coupled to the normalization unit to generate a reference current signal by performing an arithmetic operation, wherein the arithmetic operation involves the normalized signal; and a gate drive signal generation unit, used to generate a gate drive signal, wherein the duty of the gate drive signal is determined by a voltage comparison of the reference current signal and a current sensing signal.
