Abstract

PURPOSE:To improve the efficiency of a high-frequency power source, by a method wherein an impedance matching means is provided between the load and the high- frequency high-voltage source which is actuated by a low-frequency power source. CONSTITUTION:A power source 5 which generates high frequency high voltage is actuated by a low-frequency alternating current source 1, and a matching circuit 7 is inserted between the source 5 and the load 3. The impedance of the matching circuit 7 is so determined that the interior impedance of the source 5 and the exterior impedance which includes the matching circuit 7 and the load 3 are matched. For example, in case of applying above configulation to the load 3 such as a discharge lamp, the impedance Z1 of a high-frequency inductor 71 as a matching means is so determined that the sum of Z1 and the impedance of the discharge lamp 3 is equal to the interior impedance of the intermittent high-voltage circuit 5.
