Claim Text:
1. An interleaved forward voltage converter comprising: a first converter stage comprising a first transformer having a turns ratio N having a primary winding having one terminal coupled to a source of input voltage and another terminal coupled to a first switching transistor and a second switching transistor; a first secondary winding for the first transformer having a first terminal coupled to a first terminal of a filter inductor and a second terminal coupled to a first diode and a third switching transistor; a second converter stage comprising a second transformer having a turns ratio N and having a primary winding having one terminal coupled to the source of input voltage and another terminal coupled to a reference voltage source; a second secondary winding for the second transformer having a first terminal coupled to the first terminal of the filter inductor to a second diode and a second terminal coupled to the reference voltage source; wherein the third switching transistor being coupled between the second terminal of the first secondary winding of the first transformer and the first terminal of the second secondary winding of the second transformer; and further comprising a third diode coupled in series with the third switching transistor.
