This application is a compact low cost claimed topology of ballast for a discharge lamp, which can provide high power factor and low total harmonic distortion and has fewer parts than the prior art. This topology provides a low crest factor and quick start feature, which increases the number of starts and the lamp life of the product. By using a field effect transistor instead of a bipolar junction transistor as the main switch and the lower value of the electrolysis, the cost and size is… CONTINUE READING
