Abstract
The present invention pertains to a boost power factor correction (PFC) controller. In one embodiment, a boost PFC controller for an AC/DC converter can include: an off signal generator that compares an inductor current sample signal against a first control signal, where the inductor current sample signal increases during an on time of a power switch of the AC/DC converter, and the off signal generator generates an off signal when the inductor current sample signal reaches the first control signal level; and an on signal generator that compares a second control signal against a third control signal, where the second control signal increases during the off time of the power switch, and the on signal generator generates an on signal when the second control signal reaches the third control signal level.
