A New Transformer Design Method Aiming at the Electromagnetic Compatibility of Flyback Power Converter

A properly designed transformer contributes a lot to the whole electromagnetic compatibility of a switch mode power supply which contains transformer(transformers) in its topology.The traditional EMC design method of transformer,including the source and transmission path of the common mode noise in flyback converter,is introduced.A new transformer EMC design method based on the idea of active noise nodes balance is proposed.Experimental results show that the new method provides a superior noise suppressing ...
