3. Conducted EMC emission model
The EMC emission models considered in this article are represented by equivalent electrical circuits. The models are composed of the voltage or current sources introducing the noise and/or fluctuations and/or transient offsets disturbing the circuit operation. We then take into account the equivalent electrical behavior of each component that accentuates EMC noise circulation. The following paragraphs briefly describe the parameters taken into account to illustrate our method.
3.1 Emission noise
By hypothesis, the usage scenario of our test circuit is assimilated to operation in a residential environment. During use, the circuit is considered to be powered by a mains supply with an AC voltage of amplitude
