1. A power factor correction apparatus comprising:

  • a multiplier component being configured to process a first input signal and a second input signal, the first input signal being associated with a rectified alternating current signal, the second input signal being associated with an error signal, the multiplier component further being configured to generate a first output signal based on the first input signal and the second input signal;

    a comparator component being configured to process a third input signal and fourth input signal, the third input signal being associated with the first output signal, the comparator component further being configured to generate a second output signal based on the third input signal and the fourth input signal;

    a timing component being configured to receive a fifth input signal at a first time and generate a third output signal based on the fifth input signal at a second time;

    a switch controller being configured to generate a first control signal based on at least second output signal and the third output signal, the first control signal being capable of causing a switch to turn off,wherein;

    the fifth input signal is associated with the control signal;

    the time difference between the first time and the second time is predetermined based on at a characteristic of the apparatus.
