Abstract
An output of a rectifying circuit (), which rectifies commercial AC power, is supplied to an inverter () through a power factor correction circuit (). The output of the inverter () is voltage-transformed in a transformer (), rectified in a rectifying circuit () and is applied to a xenon lamp (). A secondary winding () of a transformer () of an igniter () is connected between the rectifying circuit () and the xenon lamp () in order to generate an arc in the xenon lamp (). A pulse generator provides a pulse for a short time period to a primary winding () of the transformer (). An auxiliary power supply () supplies arc-sustaining current prepared based on the commercial AC power to the junction of the rectifying circuit () and the secondary winding () of the transformer ().
