Abstract
An apparatus and a method for driving a fluorescent lamp are provided. The apparatus submitted by the present invention includes an LC resonator and an automatic frequency tracing circuit. The LC resonator is used for receiving and converting a square signal to generate a sinusoidal driving signal for driving the fluorescent lamp. The automatic frequency tracing circuit is used for making a frequency of the sinusoidal driving signal automatically following a resonant frequency of the LC resonator according to a feedback signal related to the sinusoidal driving signal.
