Abstract
A full-bridge phase-shift converter with voltage clamping includes a transformer, a primary-side circuit, and a secondary-side circuit. The secondary-side circuit includes a first synchronous rectifying switch, a second synchronous rectifying switch, an output inductor, a plurality of diodes, a capacitor, an energy-releasing unit, and an output capacitor. The capacitor provides a clamping voltage. The energy-releasing unit is coupled to the capacitor in parallel, and converts the clamping voltage into an output voltage. The output capacitor is coupled to the energy-releasing unit in parallel, and provides the output voltage.
