LOSSLESS SNUBBER ABSTRACT OF THE INVENTION A capacitor connected directly across the terminals of the primary inductance of a transformer of a switched mode power supply and a separately wound inductor connected between the primary inductance and the switching power transistor which form a lossless snubber circuit. The snubber circuit is more efficient since resistors are not used to dissipate the energy as unwanted heat. The capacitor increases the transistor turn off voltage rise time, thereby reducing radiated emissions. The inductor reduces emissions appreciably by absorbing the ringing that would otherwise occur after the transistor is turned fully off and increases the transistor turn on time to allow reduced emissions.
