Abstract:
1. A bi-directional solid slate switch comprising: at least two main transistors, each comprising the control terminals of the two main transistors being electrically connected and the second terminals of the two main transistors being electrically connected, the control terminals being electrically connected to the second terminals through at least one device having an impedance, a first switch control input for connection to the control terminals of the two main transistors, for selectively applying an activating control signal voltage from one side of an electric signal voltage source, and a second switch control input for connecting the third terminal of one of the main transistors to the other side of the electric signal voltage source, wherein when the activating control signal voltage is applied to the switch control inputs, an electric current can be conducted through the main transistors, and such that a rate of change of the voltage on the first switch control input depends, at least in part, on a magnitude of any negative voltage on the other third terminal with respect to the connection between the second switch control input and its thereto connected third terminal.
