Abstract
A power factor correction circuit for a boost converter comprises a voltage converting means and a voltage-to-time converting means. The voltage converting means converts a supply voltage based on a time period of a turn-on duration Tand a turn-off duration Tof the boost converter into an output voltage. The voltage-to-time converting means generates the turn-on duration Tbased on the output voltage from the voltage converting means. The power factor correction circuit adjusts the turn-on duration Tsubstantially in accordance with the following relationship: The first parameter includes at least one first process-dependent parameter and the second parameter includes at least one second process-dependent parameter. The first process-dependent parameter and the second process-dependent parameter are same electrical characteristic associated with different circuit components in the power factor correction circuit.
