Simulation of the dynamic behaviour of HID lamps based on electrical conductance

This paper proposes a model for HID lamps based on equivalent conductance. Starting from fundamental physical principles a general equation is obtained. The model was developed using SIMULINK/MATLAB modeling tool and verified against experimental results. It was found that the model proposed emulates faithfully electrical response of a high pressure sodium (HPS) lamp at low (50 Hz) and high frequency (100 kHz) operation.
