<p num="1"><br/><br/><br/>Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by <br/>using energy stored in a capacitor at a breakdown for creating an ignition arc <br/>at the electrodes of a resistive arc probe, having a semiconductor resistive <br/>film across spark electrodes of the resistive arc probe, designed to preclude <br/>interference of contaminants with conduction of an ignition arc across an <br/>established current path between the electrodes of the resistive arc probe. An <br/>air gap and a resistive arc probe are connected in series. A first high <br/>voltage power supply develops a first direct current voltage across a <br/>capacitor, which is supplied as a voltage across the air gap and the resistive <br/>arc probe. A second high voltage power supply supplies a second pulsed voltage <br/>across the air gap and the resistive arc probe, wherein the second pulsed <br/>voltage is substantially higher than the first direct current voltage, aid the <br/>second pulsed voltage jumps the gap of the air gap and thus initiates and <br/>ignition arc.<br/>
