Abstract: This invention relates to a power converter (1 ) comprising a converter input (3), a converter output (5), a power factor correction (PFC) stage (7) and an isolation stage (9). The PFC stage (7) is implemented by way of a buck PFC with low side drive and low side current sensing, There is provided a third stage, an intermediate buck pre- regulation stage (11), intermediate the buck PFC stage (7) and the isolation stage (9), Control of the power converter output voltage is achieved by varying the duty cycle of the intermediate buck pre-regulation stage (11 ) and therefore the isolation stage (9) may be an unregulated stage operated as a fixed DCDC voltage converter. The isolation stage (9) is operated as a 50%-50% duly cycle double ended stage. The configuration of power converter allows for a relatively inexpensive, highly efficient converter with 90%+ efficiency and simplified control.

Abstract: The invention relates to a power converter (1) comprising a magnetic core (3) and a plurality of sub-converters each having a primary winding (17. 19) and a secondary winding. The magnetic core (3) comprises an inner leg (7) and a plurality of outer legs (5, 9), each of the outer legs (5, 9) having a gap (11, 13) formed therein. The primary winding (17) of one sub-converter is wound around an outer leg and the primary winding (19) of another sub-converter is wound around another outer leg. The primary windings (17, 19) are formed from a unitary winding (21) which is wound around the legs (5, 7, 9) in a continuous fashion. The primary windings (17, 19) are mounted on a printed circuit board (PCB) (15) and interconnects between turns of the primary windings are achieved using vias (27, 29) at the ends (23, 25) of the unitary winding. The vias may be conveniently placed in the corner sections or the PCB (15).
