Abstract
The performance characteristics of a lead peaked ballast is analyzed using the equivalent circuit model and the discharge voltage-current model. The operating temperature of the lamp is 40°C or 0°C. The obtained results are as follows:<BR>1) The discharge current consists of the currents flowing through the leakage inductance and the saturated inductance based on the splined-gap in the secondary iron core. The discharge current waveform can be controlled by adjusting the ratio of the two current components and the phase difference between them.<BR>2) The crest factor of the discharge current takes a minimum at a certain N2/N1 ratio when the peak of the output voltage under a no-load codition is kept constant, where N2/N1 is the ratio of the secondary and the primary winding numbers.<BR>3) The crest factor of the discharge current decreases with increasing the width of the splined-gap, when the output wattage is kept constant by adjusting the other circuit parameters.<BR>4) The off-time is produced at the reignition phase when the reignition voltage of the lamp overcomes the applied voltage supplied through the circuit.<BR>5) When the operating temperature of the lamp is low, the applied voltage through the circuit decreases, while the reignition voltage of the lamp increases.<BR>6) The crest factor of the discharge current decreases while the applied voltage increases, when both of the splined-gap width and the capacitance increase.
