Abstract: In modern industrial era demand for electricity is increasing, as a result there is a rapid increase in demand for power generation and transmission. Various researches are going on in order to deliver the efficient energy systems. One such effective method for optimizing the efficiency of inductive devices such as transformer and inductors in cost efficient way has been discussed in this paper. Inductive circuits are used in all electronic devices; the values of impedance of this circuit determine the total efficiency of an instrument or a device. The significant loss in the transformer is the leakage of magnetic flux and Eddy current. By introducing a filler material, which is abundantly available in the earth’s crust; these losses can be minimized. An amorphous filler material which has high permeability and lower electrical conductivity is introduced in the air gap of soft-core iron transformer which significantly reduces the magnetic flux leakage through the lateral sides of the transformer, in turn, enhances the magnetic coupling between the primary coil and the secondary coil of the transformer. Thus, the varying magnetic field around the coil is utilized to the possible extent, as a result the efficiency of a device is optimized. A prototype of a step-down transformer using this filler material has been designed in which the efficiency is increased by 8.306% when compared to the traditional transformers used today. The main contribution of this research is the introduction of a technique for optimizing the magnetic coupling between the primary and secondary coils, which imparts greater efficiency to the transformer and minimizes the overall transformer materials and production cost.
