Abstract
An electromechanical switching protection system includes an electromechanical switchgear having contacts configured to selectively open and close in response to a control signal, and a junction field effect transistor (JFET) device electrically connected in series with the electromechanical switchgear between an input terminal and an output terminal of the electromechanical switching protection system, a gate of the JFET device being electrically connected to the output terminal.
Claims14
An electromechanical switching protection system comprising:
- an electromechanical switchgear having contacts configured to selectively open and close via an electromagnet in response to a control signal, the contacts of the electromechanical switchgear being galvanically isolated from a source of the control signal;
- and
- a junction field effect transistor (JFET) device electrically connected in series with the electromechanical switchgear between an input terminal and an output terminal of the electromechanical switching protection system, a gate of the JFET device being electrically connected to the output terminal and directly connected to a contact of the contacts of the electromechanical switchgear.
