A method and circuit for converting high voltage AC to low voltage DC using a switched power supply and rising edge conduction has an alternating current (AC) power source. A rectifier is coupled to the AC power source. A switching device is coupled to the rectifier. The switching device is opened and closed only during rising edge conduction. Control circuitry is coupled to the switching device for opening and closing of the switching device only during rising edge conduction. A storage capacitive element is coupled to the switching device.
