ABSTRACT:
A snubber circuit reduces the magnitude of a flyback voltage pulse across a switching transistor caused by a transformer while incurring essentially no power losses. In one embodiment, the snubber circuit modulates the voltage pulse across the switching transistor so that the sum of the input line voltage and the flyback voltage pulse remain substantially independent of input voltage.
