PSpice model of discharge lamps with saturated magnetic ballast and non-square arc voltage

High intensity discharge lamps with magnetic ballast are energy-efficient lighting devices commonly used in industrial and public installations. These lamps can be important pollution loads, and their harmonic modeling has been extensively studied considering linear magnetic ballast and square arc voltage waveform. Previous assumptions can be far from describing actual lamp behavior, affecting the accuracy of the model. This paper proposes a PSpice model of high intensity discharge lamps considering both the non-linear behavior of the magnetic ballast and the non-square waveform of the arc voltage. The PSpice model is successfully validated with lab experimental measurements.
