Abstract
A power converter and control circuit are provided. The control circuit has a power controller for turning on the power switch to maintain a desired output voltage and mode selection switch provides a mode selection signal. Depending on the magnitude of an input voltage of the power converter, in which the mode selection circuit compares the input voltage of the power converter with a reference voltage, a modulation controller is configured to turn on a modulation switch to activate the capacitor according to the mode selection signal.
