Abstract
A direct current to alternating current (DC/AC) inverter is for driving a fluorescent lamp through quasi sine wave generation. The DC/AC inverter includes a frequency generator for generating a reference signal and a modulation signal, a pulse width modulator coupled to the frequency generator for providing a pulse width modulation signal according to said modulation signal, a driver circuit coupled to the pulse width modulator for generating at least one driving signal according to the pulse width modulation signal and the reference signal, a half bridge power switch unit coupled to the driver circuit, and a resonant tank coupled to the fluorescent lamp for outputting a quasi sine wave to drive the fluorescent lamp.
