Implementation of High-Frequency Emergency Lighting Electronic Ballast for Telecommunication Power System

摘要

High frequency emergency lighting apparatus for telecommunication power system is proposed in this paper. The proposed circuit configuration comprises an electronic ballast, a line voltage detector, and a charger/discharger. To reduce the size of the system structure and to raise the system efficiency, the class E inverter and the bi-directional converter are employed, respectively. A simple model and design procedure are both constructed by reasonable simplification and combination skills. The overall system efficiency is promoted above 91%. Complete analysis and design considerations are discussed in detail in this paper. Experimental results agree with the theoretical prediction.
