Abstract

The invention relates to an electronic ballasting method of a gas discharge lamp; a start high frequency impulse is generated by a control unit and a high power chopper of a power conversion unit is driven by the control unit; after alternating current is rectified the full-wave, a pulsating direct current is processed by high frequency chopping of high power chopper and by transformation, after passing through a high frequency inductor, a high pressure trigger is started by the obtained pulsating direct current and a start high frequency alternating current is outputted. A power supply high frequency impulse is produced in the control unit and high frequency alternating current energy is provided continuously in a new frequency by the power conversion unit. The invention also provides an electric ballast of the gas discharge lamp, comprising a control unit and a power conversion unit; the control unit is composed of an impulse generator, a pulse distributor, a power driver, a high frequency transformer and a adjustment protection unit; the power conversion unit is composed of a rectifier, a high frequency chopper, a high frequency transformer, a high frequency inductor, a high frequency current transformer and a high pressure trigger. The invention solves the problems of the reliability and stability of the electronic ballast and the energy saving.

Description

technical field [0001] The invention relates to an electronic ballast method for a gas discharge lamp and a ballast thereof, in particular to an electronic ballast method for a high-power gas discharge lamp and a ballast thereof, in particular to a The invention discloses a dual-operating-frequency electronic ballast method and a ballast thereof by increasing the frequency and adopting inductive reactance for a high-power gas discharge lamp. Background technique [0002] Electronic ballasts for high-power gas discharge lamps above 250W, such as metal halide lamps and sodium lamps, have strict requirements for reliability, stability and high performance-price ratio due to the place of use and their own characteristics. Its basic performance should meet: constant output power, high power factor, wide temperature range, AC power supply mode to prevent electrode polarization, no acoustic resonance, 2.5 ~ 4kV lighting trigger voltage at the moment of start-up, and a certain power...
