Abstract

A power conversion system utilizes an inductive device having a magnetic core formed of a plurality of wires that extend through the inductive device, and beyond its electric windings. The ends of the wires are formed around the electric windings, meet, and are connected together enveloping the magnetic core and windings forming a complete magnetic circuit. The inductive device may be a transformer used in a power supply, inverter, or other device with two or more windings, a choke coil with only one winding used in a ballast, power supply, inverter, or other inductive device. The power conversion system may further include a rectifier, a filter, and a regulator a so called analog system or components as in a switch mode system. In one embodiment of the power conversion system one or all of the rectification, filtering or regulation components or other components may be positioned within a housing formed by the magnetic core to provide physical protection and protection from the intrusion of electromagnetic interference from external sources.
