Hello,

I'm currently using PLL available from matlab simpowersystems to simulate 1-phase inverter for PV connected to grid system. There are 3 Outputs from this PLL model: frequency, wt, and sin_cos in vector form.

My problem is: I need the signal amplitude? I'm actually trying to figure out where's the Vout of the Phase-locked loop?

Can someone tell me how to get the amplitude ?'

thank U very much!

Hi Akki,

I would take a look into the "Sensors and Measurements" library to see if one of those blocks will get you the amplitude that you need. You could use something like the RMS block directly, or feed the output of your PLL into something like a Fundamental (PLL-Driven) block.
