Abstract
A control method and a control circuit for a power factor correction (PFC) circuit are provided. The control method for the PFC circuit includes the following steps. Whether a recoverable protection action is occurred or stopped is determined. During the recoverable protection action, a count value is counted. When the recoverable protection action is stopped, a discharge current of an output capacitor of the PFC circuit is analyzed at least according to the count value. An output voltage controller is updated according to the discharge current.
