Abstract
A switch arrangement for interruption of an electrical current in a circuit with a large self-induction. One application of the switch arrangement is for systems where energy stored in an inductor is to be transferred to a load. In this case, the switch arrangement is coupled in parallel with the load. The switch arrangement consists of a current interrupting means and a plurality of thyristors being connected in series in their forward direction. A circuit comprised of a plurality of serially connected sets of a resistor and a nonlinear element is connected in parallel with the serially connected current interrupting means and thyristors, the nonlinear element impeding flow of current through it when the voltage, or the time integral of the voltage thereacross is small, and more fully allowing current to flow therethrough when the voltage, or the time integral of the voltage is large. One of the resistor-nonlinear element sets is associated with one of the thyristors. A plurality of capacitors is connected between the resistor-nonlinear element circuit and the thyristors, the capacitors being connected between respective associated resistor-nonlinear element sets and thyristors.
