Abstract
A static relay system configured to be connected in series with an electrical load supplied with AC current, including: two series-connected field-effect transistors fabricated in a material having a high bandgap energy; a detector detecting a threshold of a voltage across the terminals of each of the transistors or of the two transistors; an electromechanical relay connected in series with the transistors; and a controller for opening at least one transistor or the electromechanical relay when the threshold voltage is exceeded.
