Abstract
The IGBT (Insulated Gate Bipolar Transistor) is a modern solid-state switch with wide spread applications in power electronics. However, little information is available on the performance and reliability of the switch in pulsed power supplies used for the excitation of CO2 TEA and excimer lasers. Results of reliability test conducted on a high-power, high-voltage IGBT are presented with additional focus on the measurement technique. It is found that IGBTs can be reliably used in pulsed power supplies where the peak switching current exceeds the average current rating up to five times. Furthermore, IGBTs can be reliably connected in series to increase the switch operating voltage.
