Mòd komen induktè toufe a se yon pati enpòtan nan switch ekipman pou pouvwa, konvètisè frekans, ekipman pou UPS pouvwa ak sou sa. Prensip k ap travay li yo: lè k ap travay aktyèl la ap koule nan de coils opoze likid, de pwodui mayetik jaden H1 ak H2 pwodui. Nan tan sa a, aktyèl la k ap travay sitou dmèd pa rezistans a bobin ohmik ak enduktans a flit ti nan frekansibl fonksyònman opere. Si gen siyal entèferans ki ap koule tankou dlo nan bobin lan, bobin an prezante yon gwo enpedans, ki pwodui yon efè tranpaj fò pou atenye siyal la entèferans.

The common mode inductor choke is an important part of switching power supply, frequency converter, UPS power supply and so on. Its working principle: when the working current flows through two winding opposite coils, two counteracting magnetic fields H1 and H2 are produced. At this time, the working current is mainly damped by the coil ohmic resistance and the small leakage inductance at negligible operating frequency. If there is interference signal flowing through the coil, the coil presents a high impedance, producing a strong damping effect to attenuate the interference signal.
