Properties of optimum power transformer design

THE DESIGN of electronic power transformers and other electromagnetic devices usually presents so many requirements with regard to choice of materials, thermal limitations, circuit characteristics, and insulation problems that it is difficult to obtain the best design from the standpoint of weight, volume, losses, or cost. After choices of insulating, magnetic, and conducting materials have been made, the most important requirements for an optimum transformer design are use of satisfactory proportions, selection of type of core construction, and use of an optimum core flux density.
