A Design Tradeoff Relationship Between Thyristor Ratings

Designers of high-power circuits have not previously been able to quantitatively estimate the design tradeoffs which are available between the blocking voltage, current density, and turnoff time of a thyristor. In this paper, a new tradeoff relationship is derived by combining simple relationships from well-known device theory. The constants in this relationship are empirically adjusted to correlate with present commercial thyristors.
