SCR Test Circuit (NI007E)

This circuit is used to test SCRs like the ones of TIC series. The simulation shows the power line half-cycles applied to a load. The load is an incandescent lamp.




The wave shapes in the circuit can be displayed by the virtual oscilloscope of the MultiSIM. Observe the adjustments for a correct display. The upper signal is the voltage applied to the load and the lower signal are the trigger pulses produced by the diac.
