Transformer design as a key for efficiency optimization

This paper gives some comparison figures in terms of transformer windings design. It shows that, irrespective of any special or new material use, the design itself constitutes a very important parameter influencing efficiency. Low, medium and high power transformers have been designed with the goal of achieving minimum losses for a specified rated power. The gain in terms of losses reduction is up to 25 percent, while the transformer cost and length are the lowest as well.
