References(4) A model for the analysis of a lead - peaked ballast characteristics is developed. The model is derived using the equivalent circuit method of magnetic circuit. The magnetic path is divided into nine parts, and are expressed by equivalent inductors respectively. Iron loss at each part is represented by an equivalent resistance. For a discharge load, the discharge voltage - current model is adopted. Using the developed model, input and output characteristics are calculated and compared with the measured values at no-load, short-circuit load and discharge load condition, respectively. The calculated results agree well with the measured results both in waveforms and effective values.
