Is it possible to change the Resistor in Simulation at a particular time point?

Hello everyone,

I have a question about the Simulation in PLECS.

I have built a circuit model in PLECS and I want to change the value of resistor in Simulation at a particular time point.

For example:

00.2 R3=50; (t=time)

I have tried to write it in Simulation script, but I don’t know how to describe the time.

I am so confused about it. It’s appreciated if you could help me solve the problem. Thanks a lot!

You cannot easily change the resistor value in a running simulation.

The usual approach is to use a second resistor in parallel or series to the first resistor and use a switch to connect / disconnect it. The switch can be triggered by a step function, for example.
