Abstract

Although an electrical transformer can be developed efficiency by many novel approaches, the alternative methods for the transformer efficiency improvement have been proposed by researcher frequently. An electrical transformer is one of main components for many electric appliances. While the transformer of the electric appliance has high efficiency, thus the electric appliance will consume lower power energy. This paper proposes for modifying transformer parameters by using central composite design (CCD) method to improve the efficiency of transformer. Technically, the transformer structural parameters such as core thickness, winding turn number and conductor area are analyzed and modified by the central composite design. Consequently, the proposed method is positive for improving the efficiency of single phase transformer. The efficiency of the innovative transformer is higher 3.7% comparing with the prototype transformer. Also the cost of the innovative transformer can be reduced as 4.09% comparing with the prototype transformer.
