What is the basic structure and/or construction style of electronic transformers?
Many current transformers are wound on toroidal cores; hence, the transformer is referred to as a toroidal current transformer. Many transformer coils are wound on bobbins (spools) or tubes. The transformer core is inserted into and around the coil. These transformers may be referred to as bobbin wound or tube wound structures. There are many core shapes available: E, E-I, U, U-I, Pot, RM, PQ, EP, EFD, and others.
