PROBLEM TO BE SOLVED: To propose an ignitor structure, especially for a power source synchronous type ignitor used to ignite fuel for a gas or a petroleum combustor or a heater, and to provide such power source cycle synchronous type ignitor, which is compact in size and capable of obtaining high power. SOLUTION: The ignitor performing oscillation in response to a commercial source cycle of a frequency f is provided with a triggering circuit, a voltage doubler circuit, and a switching circuit on the primary side of a transformer and a discharge electrode on the secondary side. The triggering circuit is provided with a condenser C3 and resistance R1. The condenser C3 and the resistance R1 are set at C3×R1<(1/4f). COPYRIGHT: (C)2004,JPO&NCIPI
