Is it possible to design a converter in SEPIC topology with an isolation between input and output. if so then how to provide isolation?

Scroll to page 71.

 

Instead of using two inductors of same value i can use transformer to give isolation. Is that correct?

 

The schematic shows a symbol that represents an iron core transformer.
It will need to be designed for the frequency being used.
