Transformer Shielding Technique for Common Mode Noise Reduction in Isolated Converters

Description:

This innovation presents a universal method to reduce the common mode noise in isolated converters by eliminating the noise path in the inter-winding capacitor of the transformer. It is suitable in both typical winding transformers and PCB winding transformers. This innovation also provides a method to reduce common mode noise using balance concept. This method can easily control the parasitic capacitance that is suitable for mass production.
