Abstract:
A DC-DC converter includes a full-bridge circuit connected to a primary winding of a transformer and a full-bridge circuit connected to a secondary winding of the transformer. The full-bridge circuit includes a first series circuit including a first set of switching elements, a second series circuit including a second set of switching elements, a first charge-discharge capacitor connected to a node between a first pair of the first switching elements and a node between a second pair of first switching elements, and a second charge-discharge capacitor connected to a node between the a first pair of the second switching elements and a node between a second pair of the second switching elements. The full-bridge circuit can operate in one of a full-bridge operation mode and a half-bridge operation mode. The disclosed DC-DC converter can constantly operate with high efficiency even when the variation range of a load is wide.

Claim (Index 2):
The direct current-to-direct current converter according to  claim 1 , wherein the controller performs the switching control to output voltages at five levels from the first full-bridge circuit by switching between the full-bridge operation mode and the half-bridge operation mode during one period of a driving frequency of the first full-bridge circuit.
