Abstract
An electronic ballast employing the voltage source-charge pump power factor correction concept is presented in this paper. Such characteristics as reliability, simplicity, and a small number of components are found in this electronic ballast. From the developed mathematical analysis, the unity power factor condition is obtained. Experimental results for a prototype applying the developed methodology to two 40-W lamps, using a fixed frequency drive, and to a second prototype with two 40-W lamps, using a self-oscillating drive, prove the efficiency of the proposed electronic ballast.
