  • High intensity discharge lamp magnetic/electronic ballast
    Patent number: 6577075
    Abstract: A metal halide magnetic/electronic ballast with a compensation function for adjustment in autotransformer output voltage, which applies the compensation in various steps of voltage, to maintain the power constant. The metal halide ballast provides constant monitoring of the autotransformer input voltage, enabling the level to be stepped by triac switching. The triac switching is controlled by a switching control provided by a microcontroller. Less components are required, making the present invention simpler, less expensive to manufacture and more reliable.
    Type: Grant
