Abstract
PURPOSE:To effectively reduce high-frequency noises caused by transistors, by connecting an inductor between one output terminal of a rectifier and the emitters of the transistors. CONSTITUTION:DC power is supplied by a commercial power source 1, a rectifier 2 and a smoothing capacitor 3 to drive a high-frequency generator 4 to produce high-frequency power. The high frequency power is applied to a discharge lamp 11, which is a load. The lamp is thus lighted on. An inductor 8 is coupled between one output terminal of a rectifier 2 and the emitters of transistors 5, 6 so that high- frequency noises caused by the switching of the transistors 5, 6 are prevented from being transmitted to a separate electric machine through power lines or the like.
