In this transformer model, Electrical power transfer is a static device which transforms electrical energy from one circuit to another without any direct electrical connection and with the help of mutual induction between to windings. It transforms power from one circuit to another without changing its frequency but may be in different voltage level. Basically transformer is divided into two parts step up and step down transformer, in step up transformer secondary side voltage is higher than primary side and for step down transformer it just opposite to the step up transformer.
