ABSTRACT:
A semiconductor switch has a pair of PNPN switches connected in an inverse-parallel mode and each includes a switching circuit for protection against the rate effect. Each switch has its gate terminal multi-connected through a capacitive element to provide a terminal, which is connected to the output terminal of a control circuit for generating a voltage pulse in a repetitive manner to bear the difference of potential between the PNPN switches and a capacitive element by means of the capacitive element and to drive the PNPN switches with the aid of a variation of voltage produced in the control circuit.
