Title: Self protecting solid state switch
Inventor: GARDNER NIGEL CARRINGTON
IPC: H03K17/082
Filed: 1983-08-10
Abstract: The control circuit of a solid state switch 13 incorporates means to prevent overload current passing through the switch. A further switch 29 is connected in series with a voltage detector 20 across the load terminals 16, 17 of the switch 13. Drivers 100, 200 are connected to control terminals 11, 12 and 32, 33 of the switches 13, 29 to supply clock pulses from clock 2 under the control of gates 50 and 3 which can be opened by application of a pulse to start terminal 1. Thus, when start pin 1 is high control pulses switch both switches 13 and 29 into a conducting state. The voltage detector 20 is responsive to excessive load current being drawn through the switch 13 to actuate clock 18 to switch latch 28 thereby closing gate 50 and inhibiting supply of control pulses to switches 13 and 29 so that they assume an open circuit state. A dump switch 10 can be connected across terminals 11 and 12 of the switch 13 to assume a closed circuit state in response to triggering of the latch 28. The self protecting switch can also be employed with a three phase supply. <IMAGE>
