Abstract
When the first switch is on, the ignition capacitor is charged up to a voltage value whose absolute value is larger than an output voltage value of a DC power source, through resonance caused by a resonance coil and the ignition capacitor; when the second switch is on, the ignition capacitor supplies energy to the ignition coil device, and when the second switch is off, the energy is released and a high voltage is applied across electrodes of an ignition plug.
