A General Transformer Evaluation Method for Common-Mode Noise Behavior

Energies, 2019
In isolated power converters, the transformer is a key part of voltage transformation and isolation. Since common-mode (CM) noise is rather difficult to suppress compared with different-mode (DM) noise, more and more scholars are paying attention to the ...

A Bidirectional Absorptive Common-Mode Filter Based on Interdigitated Microstrip Coupled Lines for 5G “Green” Communications

IEEE Access, 2020
This paper proposes a bidirectional absorptive common-mode filter (A-CMF) for 5G “green” communication systems. The A-CMF is a balanced-to-balanced structure using interdigitated coupled lines to replace normal double parallel-coupled lines
