Abstract:
A charging path is provided for the charging of an bootstrap capacitor that stores a driver power supply voltage for driving an active clamp switch transistor in a flyback converter. The charging path couples charge from an active clamp capacitor to charge the bootstrap capacitor.

Claim (Index 1):
A flyback converter, comprising:\n an active clamp capacitor; a bootstrap capacitor for storing a driver power supply voltage for driving an active clamp switch transistor connected to a positive plate of the active clamp capacitor, wherein the active clamp capacitor has a negative plate connected to a primary winding of a transformer; a power supply capacitor for storing a power supply voltage for a controller for controlling the switching of a power switch transistor; a first diode coupled between bootstrap capacitor and the power supply capacitor for coupling charge from the power supply capacitor to charge the bootstrap capacitor; and a second diode in series with a resistor connected between the positive plate of the active clamp capacitor and the bootstrap capacitor for coupling charge from the active clamp capacitor to charge the bootstrap capacitor.
