Abstract
A method for operating a switching power supply is provided. The method includes generating a half sine wave signal for coupling to a pulse width modulator, detecting the zero crossings of the half sine wave signal, and altering the pulse width of the supply output such that the on and off timing of the pulse width corresponds to a zero crossing of the half sine wave signal.
