چکیده
The employ of the fluorescent lamps without electrodes (electrodeless) have been increasing, because of their features such as lifetime and lumen efficiency, when compared to conventional fluorescent and high pressure sodium (HPS) lamps. This paper presents a luminous flux variation strategy using a Single Ended Primary Inductance Converter (SEPIC) for feeding of electrodeless fluorescent lamp, which also provides high power factor correction. Since the load is variable a digital compensation is used to meet the control of the specified output voltage in the project, once the dimming feature is achieved by varying the SEPIC output voltage. A microcontroller is used in order to allow a suitable control for the converter since it presents features that allows add the features to obtain dimming capability. The lumens information can be done through wireless system. Keywords Dimming control, electrodeless fluorescent lamps, electronic ballasts.

W hen considering alternative approaches to the design of dimmable electronic ballasts for fluorescent lamps, the lamp power regulation method employed is the critical factor. It determines the linearity (i.e., the linear response of the light output with the dimming control input), the smoothness of dimming and, most importantly, the stability of the light output. Both digital and analog appro...
