Abstract
A power magnetic device, a method of manufacture therefor and a power converter. The power magnetic device includes: (1) an isolation transformer having a primary winding and a secondary winding, (2) a switch coupled to the primary winding, (3) a rectifier coupled to the secondary winding and (4) an encapsulant substantially surrounding the isolation transformer, the switch and the rectifier to join the isolation transformer, the switch and the rectifier into an integrated package, the integrated package having: (a) a first power input coupled to a first end of the primary winding, (b) a second power input coupled to the switch, (c) first and second power outputs coupled to the rectifier circuit and (d) a control input coupled to the switch, the control input allowing the switch to be controlled to couple the primary winding to a source of electrical power, the power magnetic device thereby capable of employing the isolation transformer and the rectifier to convert electrical power into DC electrical power.
