Abstract

Ballast is a device needed to energize fluorescent lamps during operation. In fluorescent lighting systems, the ballast provides the proper voltage to start the lamp and then regulates the electric current flowing through the lamp to stabilize output. There are two types of ballast for fluorescent lamp: electromagnetic ballast and electronic ballast. Even though the electronic ballast has many advantages compared to electromagnetic ballast, it has high purchase cost and can only connect to one or two lamps. Therefore this project will be focusing to design electronic ballast which has high efficiency, cost effective and can operate multiple lamps. The end result of this project is the simulation result and the prototype of the product. The design process will include procedures such as research, calculation, simulation of Pspice and construction of the electronic ballast circuit. After some research, it was found that the combination of power factor correction (flyback converter) and selfoscillating inverter can build the electronic ballast which meets this project's requirement. The combination of all the circuits has been successfully simulated in Pspice software and result was obtained. The electronic components such as resistors, inductors, capacitor, and MOSFETs were bought and the prototype of the electronics ballast was built. The cost used to build the circuit is calculated and compare with the price of the electronic ballast in the market. The efficiency of the electronic ballast was calculated.
