Claim Text:
1. A hybrid dc-dc converter comprising: a pair of transformers configured to magnetically couple a primary side to a secondary side; a full-bridge converter including four switches, a first diode and a second diode connected to a third leg in series, a third diode and a fourth diode connected to a fourth leg in series, and a first transformer, wherein the four switches include two pairs of switches, the two pairs being connected to a first leg and a second leg in series, respectively, the first leg and the second leg are located at the primary side, and the third leg and the fourth leg are located at the secondary side; and a half-bridge converter including two switches connected to the second leg in series among the four switches, a resonant inductor, a resonant capacitor, a fifth diode and a sixth diode connected to the fourth leg in series, two filter capacitors, and a second transformer, wherein a secondary side of the first transformer and a secondary side of the second transformer are connected to each other in series; and the third diode, the fourth diode, the fifth diode, and the sixth diode are connected to each other in series in a same direction.
