  • Electronic controller for high-power gas discharging lamp
    Patent number: 7528557
    Abstract: An electronic controller for a high-power gas discharging lamp bulb includes a filter circuit to reduce interference and control the electromagnetic characteristics of an input power signal. A rectifier circuit electrically communicates with the filter circuit to generate a DC power signal. A power factor switching circuit electrically communicates with the rectifier circuit to increase the power factor and to stabilize the voltage and current of the power signal. A driver inversion and power control circuit electrically communicates with the power factor switching circuit to adjust to loading of the controller. An initiation trigger protective circuit electrically communicates with the driver inversion and power control circuit to control the timing of passing a trigger voltage to the lamp. An output matching circuit electrically communicates with the initiation trigger protective circuit to match the impedance of the lamp bulb connected to the output matching circuit.
