Abstract
A solid-state switch according to the invention is designed to be connected in series with a load. The switch comprises at least two electric switching means connected in parallel, measuring means designed to measure an electric voltage at the terminals of the electric switching means and a main current flowing in the load, and control means delivering a control signal to act on opening and closing according to the value of the main current. The state of conduction of the first electric switching means depends at the same time on the main current flowing in the load, on a control current, on a control voltage delivered by the control means, and on the gain of the first electric switching means.
