Abstract:
In an embodiment, a DC-DC power conversion circuit with a step-down conversion ratio of at least 12:1 is provided. The DC-DC power conversion circuit includes a half-bridge circuit arrangement, a resonant capacitor and a module including a hybrid transformer. The hybrid transformer includes a magnetic core and a primary winding electrically coupled in series with a secondary winding. The module further includes a synchronous rectifier having an output coupled between the primary winding and the secondary winding of the hybrid transformer, and an output capacitor coupled with an output of the secondary winding.

Claim (Index 16):
The DC-DC conversion circuit of  claim 15 , wherein the DC-to-DC conversion circuit is configured to provide power from a DC voltage source connected between an input terminal and a common terminal to a DC load connected between an output terminal and the common terminal, and wherein:\n the first switch comprises one end connected to an input terminal; the second switch comprises one end connected to another end of the first switch and another end connected to an output terminal; the synchronous rectifier comprises an end connected to the common terminal; the resonant capacitor has one end connected to the another end of the first switch; a resonant inductor has one end connected to another end of the resonant capacitor; the first winding of a hybrid transformer has a first end connected to another end of the resonant inductor and a second end connected to another end of the synchronous rectifier; the second winding of the hybrid transformer has a first end connected to the second of the first winding, and a second end of the second winding connected to the output terminal; the resonant inductor and the resonant capacitor form a resonant circuit during the TOFF time interval with a resonant current flowing through the first winding into the DC load; a first turns ratio n of the hybrid transformer is a total number of turns of both the first winding N 1  and the second winding N 2  divided by a number of turns of the second winding N 2  of the hybrid transformer; an input current during the TON time interval stores an inductive energy in the first and the second winding and during the TOFF time interval the stored inductive energy is transferred to the DC load through the second winding by n times higher current than the input current; a second turns ratio m of the hybrid transformer is the ratio between number of turns of the first winding N 1  and the number of turns of the second winding N 2  of the hybrid transformer; the resonant current in the first winding is amplified by the second turns ratio m of the hybrid transformer and sent to the DC load through the second winding of the hybrid transformer; a duty ratio D is ratio between the TON time interval and the switching operating cycle TS; and a DC-to-DC voltage step-down conversion ratio of the converter depends on the duty ratio D and the first turns ratio n of the hybrid transformer.
