摘要
A circuit to start an HID lamp in a high-frequency start mode and, after starting, to operate the lamp in a low-frequency operating mode is controlled, during the high-frequency start mode, to drive the lamps with a voltage that includes a high-frequency component to ignite the lamp and a unipolar or bipolar offset component to keep the lamp ignited during a transition from the high-frequency start mode to the low-frequency operating mode.
