I am designing a FWB rectifier circuit to convert 120 V AC to 5 V DC, so I need a transformer. The problem is that all the transformers in the master database in Multisim for which you can adjust the primary-to-secondary ratio don't have an option to select a specific package for Ultiboard to make the component be "real" and turn blue, and all the transformers that have an option to select a specific package are not adjustable. So how can I place a transformer that is both adjustable and can be transferred to Ultiboard?
