The invention relates to a novel DC-AC boost single-stage high-frequency inductance electronic ballast. The ballast comprises a power circuit and a control circuit, wherein the power circuit comprises a starting circuit, an energy-saving capacitor, a half-bridge switch circuit, a series capacitor, a high-frequency pulse transformer and a high-frequency inductor, and the control circuit comprises a singlechip microcomputer or an analog control circuit, an output voltage and current sampling and conditioning circuit and a driving circuit. By the ballast, direct current output from a 24V or 48V vehicle-mounted storage battery can be directly converted to a high-frequency alternating current, a required power supply is provided for lighting of a xenon lamp and other high-voltage gas discharge lamp, and the ballast is particularly and suitably used for an automobile xenon lamp and a searchlight.
