Extending the Concept of Common Mode Noise: Single Mode

 

Electronic switching circuits are used for power conversion, data communication and other applications. According to the theory of Fourier Transform, in these circuits, the periodical change of the current/voltage produces harmonics in a wide frequency spectrum. The resultant currents of these harmonics are called conducted emission (CE), and are categorized classically as … [Read more...]
