Problem With 3-phase PLL in a 12 pulse thyristor rectifer

0 votes
Hello, I have a problem with my simulation. As we know a 12 pulse igbt rectifier with a fire angle equal to zero have phase shift between voltage and current equal to zero in AC side, but in the simulation I have about 30° between them.

Maybe i have not finished understanding how 3-phase PLL works.

Thank you in advance.

Hello, can you provide a reference for what waveforms you expect to see here? The model looks like it is working correctly so it would be helpful to better understand the target operation.

Hi Kris, thank you for answering.

This is a picture of one phase of the source when a 12 pulse bridge diode is operating. Here we can see that there is not delay between current (yellow) and voltage (green). 

I expect the same behavior of 12 pulse rectifier using thyristors with fire angle equal to zero, but i have the image below where we clearly see that there is a delay between voltage and current. 


Hi again. This is helpful. Are you able to include the model of the diode rectifier version? And what Scope (name) is the second image from in the model you already provided? Thanks.
Here it is, the model of the second image.

You can see the waveforms on the scope called "Fuentes AC".  The only difference between the models is the rectifier block.
