MAGNETIC STRUCTURE AND POWER CONVERTER FOR LIGHT SOURCES

摘要

A light source for the powering of a gas lamp (26) having a power converter circuit (20) that converts a primary voltage source (30) to a high frequency ac voltage. The power converting circuit (20) having an oscillator circuit (48) that converts the primary voltage source to the high frequency ac voltage through the use of a pair of switching transistors (Q1, Q2) each connected to one of a pair of first primary windings (W3, W4) to establish a high frequency alternating current in a first secondary winding (W5). The converter circuit (20) also includes a continuous loop isolation circuit (60) that is coupled to the oscillator circuit (48) via the first secondary winding (45) and coupled to the load supplying output winding (W8) via a second primary winding (W6), the load supplying output winding (W8) being coupled to supply the high frequency ac voltage to the gas lamp (26).
