Abstract
A system and method for controlling an arc formation in corona discharge ignition system is provided. The system includes a corona igniter for receiving energy at a voltage and providing a corona discharge. An energy supply providing the energy to the corona igniter at a voltage. The system also includes a corona controller for initiating a decrease in the voltage of the energy provided to the corona igniter in response to the onset of arc formation. The voltage is decreased until the arcing is depleted, and then the voltage is increased again to resume the corona discharge. Controlling the arc formation provides improved energy efficiency during operation of the corona discharge ignition system.
