An ideal transformer is a theoretical concept used in electrical engineering to simplify calculations and analysis of transformer behavior. In an ideal transformer, it is assumed that there are no energy losses (such as resistance losses and core losses) and no leakage flux, resulting in a perfect transfer of power from the primary side to the secondary side. This means that the input power is equal to the output power and the voltage and current are inversely proportional between the primary and secondary windings (Vp/Vs = Np/Ns, Ip/Is = Ns/Np). Ideal transformers are used as a simplified model to understand and analyze real transformers in practical applications.
