| 20090302777 | PULSE GENERATOR USED FOR ELECTRONIC BALLAST - The present utility model proposes an impulse generator for driving an electronic ballast of a gas discharge lamp, the electronic ballast includes a resonance ignition circuit, characterized in that the impulse generator comprises: a micro-controller for generating a clock frequency signal, a logical time sequence control signal and a control voltage signal; a voltage controlled oscillator, coupled to the micro-controller, for receiving the logical time sequence control signal and the control voltage signal to generate oscillation and output a voltage controlled oscillating frequency signal; a phase comparator for receiving the clock frequency signal and the voltage controlled oscillating frequency signal to perform a logical exclusive-OR operation and output an impulse signal of corresponding frequency, thereby driving the resonance ignition circuit to generate a resonance voltage. In addition, the utility model also proposes an over-voltage protection circuit used for the electronic ballast. | 12-10-2009 |
