Abstract

Systems, methods, techniques and apparatuses of power switch control are disclosed. One exemplary embodiment is a power switch comprising a thyristor-based branch including a thyristor device; a FET-based branch coupled in parallel with the thyristor-based branch and including a FET device; and a controller. The controller is structured to turn on the FET device, turn on the thyristor device after turning on the FET device based on a thyristor voltage threshold, and update the thyristor voltage threshold based on a voltage measurement corresponding to the thyristor-based branch measured while the thyristor device is turned on.
