Common mode inductance (Common mode Choke), eo hape e tsejoang e le common mode choke coil , hangata e sebelisoa ho sefa mats'oao a tšitiso ea motlakase oa motlakase ho phepelo ea matla ea komporo. Moqapi oa boto, mokhoa o tloaelehileng oa inductance o boetse o bapala karolo ea EMI filtering, e sebelisetsoang ho hatella leqhubu la motlakase le hlahisoang ke mohala oa lebelo le phahameng le ho khantša ka ntle. Morekisi oa China chip inductor , Gewei Electronics, haholo-holo e etsa lipatlisiso le ho etsa li-inductors tse tšesaane tsa motlakase, li-inductors, ' maqeba a terata , li-inductors tsa motlakase , ' inductors matla, ' matla tsa maqhubu a phahameng , le li-inductors tsa mabone tse bolokang matla.

phepelo matla inductor

 

Li-inductors tsa matla li arotsoe ka mefuta e 'meli e nang le sekoaelo sa makenete le ntle le sekoaelo sa makenete, haholo-holo se entsoe ka khoele ea khoheli le khoele ea koporo. Haholo-holo e bapala karolo ea ho sefa le ho oscillation potolohong.

1. Tlhahlobo e tsoang ho sebopeho

Ka bobeli li-inductors tsa motlakase le li-inductors tsa laminated li hloka ho ntlafatsa sebopeho sa elektrode ha li rala, e le hore matla a khoheli a kahare a sehlahisoa a fetohe a ts'oanang le ho ntlafatsa matla a khoheli a sehlahisoa. Boholo ba motlakase oa motlakase o moholo ho feta oa multilayer inductor, empa ponahalo e bataletse haholoanyane.

2. Ho tsoa tlhahlobong ea hajoale

Tekanyetso ea hona joale ea li-inductors tsa matla e ka ba kholo haholo, hoo e ka bang 1A, athe tekanyo ea hona joale ea li-inductors tsa laminated hangata e ka fihla ho mashome a mA ho ea ho makholo a mA, 'me tekanyo ea hona joale ea li-inductors tse tloaelehileng tsa ferrite hangata e ka tlaase ho mashome a mA. . mA

3. Analysis ho tloha tšebeliso ea sehlahisoa

Li-inductors tsa motlakase hangata li sebelisoa ho li-loops tsa DC-DC (module ea matla) ho tsitsisa matla a hajoale le ho boloka matla. Li-inductors tse tloaelehileng tsa ferrite hangata li sebelisoa lipotolohong tsa microwave le tsa dijithale ho bapala karolo ea ho sefa ha resonance. Li-inductors tsa laminated li sebelisoa haholo ho sebetsana le matšoao a digital bakeng sa ho itšehla thajana.

 

Li-inductors tsa mokhoa o tloaelehileng li bilirectional, 'me li-inductors tsa mefuta e fapaneng li unidirectional. Mokhoa o tloaelehileng ke hore li- windings tse peli li hokahane le terata e sa nke lehlakore le terata e phelang ka ho latellana. Maqhubu a mabeli a na le kenyeletso le tlhahiso e ts'oanang, 'me lets'oao le tloaelehileng le sefiloeng.

Differential mode ke matsoelintsoeke, 'me filthara ea sefene e hokahantsoeng le mehala e sa nkeng lehlakore le e phelang feela e ka sefa tšitiso ea mekhoa e fapaneng.

Letšoao la Mokhoa o Tloaelehileng: Lipontšo tse peli tse ts'oanang lithapong tse sa nke lehlakore le tse phelang, ka ho latellana, li kopantsoe 'me li lohelletsoe fatše.

Letšoao la mokhoa o fapaneng: Ke loop e ts'oanang le lets'oao le molemo.
