- The thesis is used by PSpice circuit model to the characteristics of a fluorescent lamp modified form ofthe classical Cassie and Mayr equations in order to show the characteristics of HID(High-Intensity Discharge) Lamp.This is useful for applying high-frequency electric ballast for HID Lamp, and show that the result of experimentationsand simulations, such as lamp rating, input voltage, high-frequency electric ballast which is using the ABM circuitmodel of the low pressure sodium lamp, come to the voltage and current wave.
