| Title of Invention | IGNITER CIRCUIT WITH AN AIR GAP |
|---|---|
| Abstract | Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an ignition arc at the electrodes of a resistive art probe, having a semiconductor resistive film across spark electrodes of line resistive arc probe, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between the electrodes of the resistive are probe. An air gap and a resistive are probe are connected in series. A first high voltage power supply develops a first deirect current voltage across a capacitor, which is supplied as a voltage across the air gap and the resistive arc probe. A second high voltage power supply supplies a second pulsed voltage across the air gap and the resistive arc probe, wherein the second pulsed voltage is substantially higher than the first direcct current voltage, and the second pulsed voltage jumps the gap of the air and thus initiates an ignition arc. The first direct current voltage is current limiting thereby allowing the capacitor voltage to approach zero, and thua allo"wing the air gap to cease conducting, theresby allowing the cycle to repeat itself. A diode is positioned between the second pulsed voltage and the capacitor of the first high voltage power supply to isolate the capacitor the capacitor from the second pulsed volatage. A second capacitor is placed parralel to the resistive are probe to prevent the pulsed second high voltage from affecling the resistive arc probe. |
