Abstract
Semiconductor power devices with fast turn-on characteristics are appearing in the market. The issues in developing the devices for pulsed power applications such as gate driving technique and characterization of the devices, are summarized. SI-thyristors were characterized as a fast high current switching device. A stacked SI-thyristor switching unit was designed and tested that was operated with a repetition rate of 2kHz. Temporal and spatial behavior of carrier number densities in a silicon wafer was measured by the free-carrier absorption method with a pulsed YAG laser.
