摘要：DC power is converted by an inverter to high-frequency power, which is supplied to the primary winding of a neon transformer. One or more neon tubes are connected in series across the secondary winding of the neon transformer. A saturable reactor is connected across the secondary winding or 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.
