SIMPLE PROTECTION CIRCUIT AND ADAPTIVE FREQUENCY SWEEPING METHOD FOR CCFL INVERTER |
摘要 |
A CCFL inverter circuit integrates a feedback circuit and protection circuit together. For both in-phase and out-of-phase applications, sensed lamp voltages can be used for open lamp and short lamp detection and sensed currents can be used for open lamp detection. The driving circuit adjusts the open lamp frequency by using a duty cycle control signal so that the driving circuit can always achieve the desired lamp voltage gain.
