摘要
An interleaved forward voltage converter having a first inverter stage has a first transformer having a first secondary winding coupled to a filter inductor. A second converter stage has a second transformer having a second secondary winding coupled to the filter inductor. A diode is coupled between the first and second secondary windings to automatically connect the first and second secondary windings in series when a duty cycle of the converter exceeds 50%. An interleaved forward voltage converter can connect the two primary windings in either parallel or a series configuration. The two secondary windings can be connected in either parallel or a series configuration. Having the two primary windings in parallel and the two secondary windings in series allows the converter to operate with a lower input voltage. Having the two primary windings in series and the two secondary windings in a parallel configuration allows the converter to operate with a higher input voltage.
