A Novel Microcontroller Based Flyback Topology Electronic Ballast in Lighting Applications

This paper presents flyback based electronic ballast for lighting application with microcontroller open source platform. The proposed electronic ballast regulates current to LEDs and provide required voltage to start up the LEDs. PWM signals is used for dimming the LEDs. Dimming the lights can save energy by using dimmers, and maintenance cost also reduced. Lights which is controlled by switch having only two stages-on and off. By using dimmers, we can control the quantity of light and their fixtures provide to definite tasks, situations and moods. This electrical ballast consists of flyback converter, which is place between the input diode bridge rectifier and the output step down converter to provide required supply to lighting (LED’s). microcontroller platform is the main core of the project. The pulse-width modulation (PWM) signal is generated by microcontroller ,which is used for drive the LED’s.
