摘要： An exciter for an internal combustion engine igniter plug, comprises a continuous AC charging circuit and a discharge circuit. The discharge circuit is connectable to the plug and the charging circuit includes a transformer having a primary winding connectable to an AC power source and a secondary winding connected to the discharge circuit. The discharge circuit includes a storage capacitor connected to the transformer secondary winding such that current induced in the secondary charges the capacitor at a generally constant rate. A switching device is connected in series between the capacitor and the plug; and a trigger circuit triggers the switching device in response to charge on the capacitor; with the charging circuit and trigger circuit operating to maintain a generally constant spark rate. A current multiplier is also provided to substantially increase the peak currents delivered to the plug.
