Abstract Simulation and measurement are essential to the process of designing electronics. But they have differences in capabilities and limitation of making it happen. This paper presents the detailed implementation of an electronic ballast, for a fluorescent lamp. The circuit is commutated smoothing circuit, power switch, and driving circuit. It is a low-voltage starter, non-stroboscopic, has no noise, energy efficient, and has high power factor with very high switching speed. Characteristic results and measurements are provided with comparison to market available ballast. The circuit has been successfully applied to a 36 W lamp. Keyword Fast switching
Low ripple High frequency Ballast factor
1 Introduction The fluorescent tube is essentially a low-pressure mercury discharge lamp. The convenience and popularity of fluorescent lamp is underscored by the fact that it accounts for a great amount of light produced on our planet than any other light source. It achieved its portion of dominance starting from the 1980s, and it is estimated that today it accounts for about 80% of the artificial light used in the world. It can be manufactured in almost any shape of white and colored versions. The main disadvantage of fluorescent lamp is their negative impedance characteristics. So to connect the lamp directly to utility line, we need to prevent the lamp from the excessive flowing current and make sure they work in desired operation region. For this purpose ballast are used.

common types of ballast are electronic ballasts and magnetic ballasts. While magnetic ballasts are simple and easy in their design and operating principle, the more sophisticated electronic ballast just has too many advantages. In addition to not causing fluorescent flicker and noise like magnetic ballasts, electronic ballasts are preferred because they are smaller in size and weightless. They are also great for the environment, and they are energy efficient and help us reduce our monthly energy bill. When we use ballast in fluorescent lamps, there is an introduction of harmonics in the line and that causes very poor power factor at input. So these line current harmonics are required to be within standards. The international standards IEC61000-3-2 and its European version EN61000-3-2 are followed for detailed harmonic limits [1]. Important considerations for ballast include high power factor, low-total harmonic distortions, low electromagnetic interference, and no flickering. The electronic ballast has been designed to work for a 36 W fluor
