want to get the real-time power of the simulated single-phase AC circuit, just like the power meter

As the title, the probe only realizes the power display of the component. It is not possible to display the real-time power of the calculation of my current system. I want to detect the maximum value of the current current and voltage, and then calculate the result of the input power, but I don’t Know how it can be achieved.

Leo,

I think I understand your question, but can you may be draw a simple block diagram of what you want to simulate and share a picture of it here?

the attachment is my circuit,and i want to let it be a close-loop using the power to control the Driving frequency,how to get it work?I am just a beginner of plecs.

Hi Leo,

You can get a periodic maximum value by using a State Machine block or a C-script block. See the attached file. It uses a State Machine block to implement periodic maximum. May be you can use this as a starting point.

Hi Leo,

Instead of detecting peak values, for a more robust and a less complex solution, you can use a periodic average block. See the attached model.
