DUAL DRIVE SYSTEM FOR TRANSFORMER ISOLATED HALF BRIDGE AND FULL BRIDGE FORWARD CONVERTERS

摘要

The present invention relates to a power converter circuit for operating on a DC input voltage comprising a forward ferrite-core transformer having at least two primary windings and at least one secondary winding, at least one automatic switching device provided between the primary windings, a current sense circuit provided between the first primary winding and the automatic switching device, and a control unit having a voltage sense circuit, the control unit being connected to the automatic switching device and the current sense circuit and being configured to operate the automatic switch on the basis of an input parameter, thereby controlling the out put voltage.
