How To Improve The Efficiency Of An AC Or Laminated Transformer?

Transformer performance depends a great deal on its efficiency. In theory, a transformer is designed to never suffer from load losses. However, in reality, transformers used in real-time applications suffer from load as well as no load losses. Loss of efficiency leads to lack of transformer performance.
