Yes, please see the PLECS Demo Models library integrated into PLECS Standalone and Blockset, and you will find, for example, “Half-Bridge LLC Converter with Analysis Tools”.

With PLECS Blockset, you can type “plecslib” into the MATLAB command line. This will open the PLECS block library, which includes the fully component library, Demo Models, Analysis Tools, and extra blocks. In PLECS Standalone, you can access the models from the Window \> Demo Models menu item.

Hi,

I changed the Type2 compensator to PI controller and run the closed loop but result does not look right, do you have any comments?

Thanks
