ELECTRONIC BALLAST FOR LOW WATTAGE LIGHTING APPLICATIONS

摘要

A failsafe inexpensive electronic ballast for low wattage lighting applications comprising of a pair of complementary bipolar junction transistors (Q1, Q2) arranged in anti-parallel mode, said pair of complementary bipolar junction transistors biased partly in common base and mainly in common emitter mode thereby providing a self trigger to the said pair of complementary bipolar junction transistors to drive the said low wattage lighting application in an optimal frequency range while depriving inrush current due to elimination of electrolytic capacitor.
