<p>A power supply including a resonant converter (16, 28, 42-49, CR & LR) is provided with a current shunt (39 or 40). The current shunt (39 or 40) automatically shunts a portion of current flowing in the resonant converter at light loading of the power supply such that output current flowing in an output circuit (18, 20) connected to the power supply would be reduced toward zero as the operating frequency of the converter moves to a predetermined frequency.</p> |
