ABSTRACT:
A feedback circuit is utilized in a DC/AC inverter having a first power switch and a second power switch for driving a fluorescent lamp. The feedback circuit includes a protection circuit for disabling the first power switch and the second power switch when no fluorescent lamp is electrically connected, a first capacitor having a first terminal electrically connected to an output of the DC/AC inverter, a second capacitor having a first terminal electrically connected to a ground, and a second terminal electrically connected to a second terminal of the first capacitor, a diode having an anode electrically connected to the second terminals of the first and second capacitors, and a cathode electrically connected to the protection circuit, and a first resistor having a first terminal electrically connected to the cathode of the diode, and a second terminal electrically connected to the ground.
