Embodiment Construction
[0019] Such as figure 2 As shown, the circuit of the single-stage EMI filter of the present invention has two input terminals, two output terminals and a ground terminal, and the shell should be connected to the earth during use. The circuit includes a common mode choke coil (also known as a common mode inductor) L, and filter capacitors C1~C4. L has no effect on series-mode interference, but when common-mode interference occurs, since the magnetic flux directions of the two coils are the same, the total inductance increases rapidly after coupling, so it presents a large inductive reactance to common-mode signals, making It is not easy to pass, so it is called a common mode choke coil. Its two coils are respectively wound on low-loss, high-permeability ferrite magnetic rings. When current flows, the magnetic fields on the two coils will strengthen each other. The inductance of L is related to the rated current I of the EMI filter, see Table 1.
