Hello,
From the Window menu inside PLECS Standalone you can access the "Demo Models". In PLECS Blockset, I recommend you type 'plecslib' into the MATLAB command line, and from the PLECS library window that opens, there is a "Demos" block (see time 4:00 in this video).
These models are then listed under the "Power Supplies" category. You can also search for a topology from within the PLECS Documentation built-in.
Regards,
Kris
