Low loss static induction devices (transistors and thyristors)

To decrease the power loss, the current gain of a Bipolar mode Static Induction Transistor (BSIT) is examined with quasi one dimensional analysis. The current gain dependence on source contact area is presented with experimental, analysis, and simulated results. With regard to the Static Induction Thyristor (SIThy), switching speed improvement methods are presented to reduce the switching loss of the device. A proton irradiation or a shorting method is a useful technique for decreasing the switching time and switching loss of SIThy
