ABSTRACT:
The present invention provides an improved circuit utilizing a full-bridge inverter circuit controlled by a push-pull pulse width modulator, wherein the circuit of the invention utilizes an inverter circuit to control the electronic switches of the full-bridge inverter circuit. Thus, the push-pull pulse width modulator can control and drive the operations of the full-bridge inverter circuit. Two outputs of the push-pull pulse width modulator are connected to two inputs of the inverter circuit in order to produce four inverting signals controlling respectively four full-bridge electronic switches. The circuit of the present invention directly converts a direct current power to an alternate current power providing the energy source to cold cathode fluorescence lamps.
