Abstract:
1. A DC-DC converter, comprising: a transformer having a primary-side winding and a secondary-side winding with a center tap; a storage choke coupled between the center tap and a first output of the DC-DC converter; a rectifier circuit connected to each of the taps at the ends of the secondary-side winding and designed to generate a rectified output voltage at a second output of the DC-DC converter; a snubber circuit including a charge collection device that includes two diodes, each coupled to the taps at the ends of the secondary-side winding of the transformer, and a snubber capacitor coupled to the two diodes and designed to store resonant oscillation energy as charge occurring in the rectifier circuit, the snubber circuit switched via the rectifier circuit; a discharge circuit including a buck converter, the discharge circuit being coupled to and discharging the charge stored in the charge collection device to the first output, the buck converter including an actuation apparatus that actuates the discharge switch, the actuation apparatus including
