摘要：
This paper describes a self-oscillating electronic ballast, having fixed switching frequency, to supply four independent fluorescent lamps, with high power factor. To provide the power factor correction it was studied the modifications of the valley-fill filter, presented in the literature, choosing one that meets the HEC 61000-3-2 Class C requirements of the input current distortion. To drive the switches it was proposed a modification in the conventional self-oscillating driver, new in the literature, making it independent on the load of the ballast. So, it is built up the prototype and showed the experimental results.
