Abstract
An electronic pulsed power supplier for High Intensity Discharge (HID) lamps is presented in this paper. The pulsed power supplier is obtained from the integration of a two current source AC/DC converter and a full-bridge inverter. The electronic supply provides to the lamp a different current form excitation (crenels and superposition of pulses). The lamp is represented in a model of simulation by its conductance model and coupled to its electronic power supply. Finally, some experimental results from a laboratory prototype are shown and compared with simulation. The general objective of this work consists in studying the effect of a current pulsed power supply on the electric and photometric behaviour of the discharge lamps, intended in particular for photochemistry.
