High-frequency power supply for neon - tube

摘要

DC power is converted by an inverter (20) to high-frequency power, which is supplied to the primary winding (Wp) of a neon transformer (17). One or more neon tubes are connected in series across the secondary winding (Ws) of the neon transformer. A saturable reactor (30) is connected across the secondary winding of the neon transformer. The saturable reactor has a characteristic that its magnetic flux is saturated when the output voltage from the secondary winding of the neon transformer increases 1.1 to 2.0 times the rated voltage.
