In this circuit, I have caused an AC current to power the gate pin of the Thyristor, which in turn should allow the 10v DC current to pass even after the AC current inverses - it is not a Transistor. However, when I check to see the voltage after the Thyristor (at the Voltmeter), the value is always fluctuating from positive to negative - as you can see, the Anode pin of the Thyristor is receiving the full 10v, so why is the voltage fluctuating so much after the Cathode pin?

  • \$\begingroup\$ It is unclear what the purpose of this circuit is. What are you trying to achieve ? Where is the ground ? 10 V, is that a voltage source ? I suggest you study and try to understand other Thyristor based circuits, learn how to use a thyristor. \$\endgroup\$

  • \$\begingroup\$ You have no GND connection for your 10 V supply so there is no return path. \$\endgroup\$

This only works with high frequency AC input.

Is this what you mean?

If you want to allow lower frequencies, you would need a LC or an RC filter, where they have to be pretty large values.
