undervoltage simulation

[pinky124]

I want to simulate an undervoltage circuit. How can i simulate load side voltage so that it decreases after some time to create undervoltage condition?

Please provide more information, there are many different ways to provide undervoltage protection.

I have an undervoltage circuit which senses load voltage. If load voltage decreases from specific value it starts working. Now i want to simulate it in orcad to see if it works fine. But i have no idea how to decrease load voltage to cause undervoltage condition which triggers the circuit.

An undervoltage cicuit should do the reverse of that.

Post the schematic.

I know how undervoltage circuit works. i am simulating this circuit to check if my design works fine and for that i have to create momentary underoltage condition at load side.

I don't know what your schematic looks like so I can't help you.
