Abstract :
The steady state operation modes and the commutation zones of a single stage, high power factor ballast are studied. The design criteria to allow the ballast to operate at the optimum soft switching conditions are given. A control circuit is also proposed. High efficiency is achieved by soft switching. Experimental results verify the theoretical study
