ABSTRACT
The conversion process in power electronics requires the use of transformers and components that are frequently the heaviest and bulkiest item in the conversion circuit. They also have a significant effect upon the overall performance and efficiency of the system. Accordingly, the design of such transformers has an important influence on the overall system weight, power conversion efficiency and cost. The designer is faced with a set of constraints that must be observed in the design on any transformer. The designer should be aware of the cost difference between silicon-iron, nickel-iron, amorphous and ferrite materials. Parameters affecting others may then be a trade-off, as necessary, to achieve the most desirable design. Transformer designers have used various approaches in arriving at suitable designs. The minimum size of a transformer is usually determined either by a temperature rise limit, or by allowable voltage regulation, assuming that size and weight are to be minimized.
