Abstract: A capacitor discharge ignition (CDI) system is capable of generating intense continuous electrical discharge at a spark gap for a desired duration and may include a second controllable power switching circuit with its input terminal connected to an output terminal of a high voltage DC source device. An output terminal of the second controllable power switching circuit is connected to an input terminal of a first power switching circuit. The second controllable power switching circuit may also have a control terminal connected to an output of a controller. The first controllable power switching circuit may be used for discharging a discharge capacitor, and the second controllable power switching circuit may cause charging of the discharge capacitor. As such, an ignition current through an ignition coil of the system is enabled for any desired number of cycles during both the charge and discharge cycles of the discharge capacitor.
