Abstract

In a design of ballast for discharge lamp, various kind of protection circuit are essential for safe operation. In this paper, overvoltage and current detection, no-load detection, lamp-fault detection, end of lamp detection for protection are introduced. Individual circuit operation and their function are described with the base that all circuit form is similar with overvoltage protection circuit.
