Abstract
Various embodiments relate to a circuit for power factor correction ('PFC'), the circuit including: a mains filter and rectifier configured to generate an input voltage for power factor correction and transmit the input voltage to a PFC controller and a load block; a voltage regulator configured to regulate the input voltage and output a control signal to an adder; a mains voltage sensor configured to sense a mains voltage and output a sensed mains voltage; a bandpass filter configured to filter out frequencies in a range of resonance frequencies of the sensed mains voltage and output an additional signal; and an adder configured to add the additional signal to the control signal and output a desired input current to the PFC controller.
