Abstract :
In this paper a stability analysis based on the remaining dynamics for an HID lamp and electronic ballast without resonant tank (non resonant ballast) is presented. This analysis uses the non linear lamp model. The lamp is the metal-halogen lamp (CDM-TD70/830). The system model is based on Euler-Lagrange modeling and the average modeling technique. The resultant equations are non linear then this method is more accurate than the classical method. This graphical-stability analysis is systematic and easy to evaluate in a mathematical package (Maple, Mathematica, Matlab). To avoid the acoustic resonance phenomenon, the selected ballasts feeds the lamp with low frequency square waves, and then to stabilize the lamp current a dc-dc converter with a closed loop control stage is included. Analysis, simulations and experimental results of the selected HID lamp and electronic ballast are presented
