Abstract

The switching process of the various devices of the power supply feeding a copper vapour type laser, leads to the generation of conducted EMI. The high speed switching action by a thyratron operating at high voltage and current leads to conducted EMI. Simulation of the conducted EMI from a copper vapour laser has been done using a powerful circuit simulator software SABER. Based on the results obtained by simulation and measurement, it is proposed to design filters that will reduce the conducted EMI to acceptable levels.
