Abstract
A procedure for minimum cost design of a small low-loss low-frequency transformer is presented. The total losses of transformer can be defined to be the design constraint. The procedure for improving the accuracy of calculated total losses is the basis of the proposed total losses calculation associated with the temperature rise evaluation. The optimization technique used in this paper is based on the Genetic Algorithms. Five samples of 72 VA, 220/24 V, 50 Hz transformers have been designed and tested in order to illustrate how well the calculated total losses values using this proposed procedure matches that of the measured values obtained from the test. Finally, the simulation results of the minimum cost design with losses constraint are demonstrated. This proposed design is suitable for the design of economical transformer with total losses value options which is considerably flexible for a particular purpose.
