Abstract In this study, design and control method using low cost Micro-controller(MCU) for inverter driving circuit in fluorescence lamp is presented. Soft starting techique is adopted to reduce switching loss and moment deterioration which are induced by high speed switching frequency in inverter ballast. Performance of the ballast stabilizer and the lighting characteristic of the fluorescence lamp have been improved by stabilizing switching pulses through the Pulse Width Modulation control.
