Abstract
A DC/AC inverter provided for transforming a DC voltage source into an AC power source, wherein the AC signal is used for driving a fluorescent lamp. The inverter comprises a half-bridge switch circuitry electrically connected to the DC voltage source, for outputting an AC signal, a resonant tank electrically connected between the half-bridge switch circuitry and the fluorescent lamp, for stepping up and filtering the AC signal into a high-voltage AC power source which is supplied to a load, and a controller feeding back an output of the fluorescent lamp, providing a pulse width modulation signal for turning on and off the half-bridge switch circuitry, such that the fluorescent lamp can operate consistently and provide a consistent brightness.
