Hloov cov khoom siv hluav taws xob tsim kev ntsuas los tiv thaiv EMI
1. Txo cov cheeb tsam ntawm PCB tooj liab ntawv ntawm cov suab nrov hauv Circuit Court; Piv txwv li ntws thiab collector ntawm switching hlab, nodes ntawm thawj thiab theem nrab windings, thiab lwm yam.
2. Khaws cov khoom siv thiab cov khoom tawm kom deb ntawm cov khoom nrov nrov, xws li cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob hloov hluav taws xob, thiab lwm yam.
3. Khaws cov khoom tsis muaj suab nrov (xws li, cov khoom siv hluav taws xob tsis muaj hluav taws xob tsis muaj hluav taws xob, cov khoom siv hluav taws xob tsis muaj hluav taws xob, cov raj hloov hluav taws xob, thiab lwm yam) kom deb ntawm ntug ntawm lub qhov rooj kaw, uas zoo li yuav nyob ze rau lub ntiaj teb sab nraud xaim nyob rau hauv ib txwm ua haujlwm.
4. Yog hais tias lub transformer tsis shielded los ntawm hluav taws xob teb, cia lub shield thiab kub dab dej nyob deb ntawm lub transformer.
5. Txo thaj tsam ntawm cov voj voog tam sim no: theem nrab (tso zis) rectifiers, thawj cov khoom siv hluav taws xob hloov hluav taws xob, lub rooj vag (hauv paus) tsav circuits, pab rectifiers, thiab cov khoom siv thib ob (tso tawm) rectifiers.
6. Tsis txhob sib tov lub rooj vag (pem hauv paus) tsav rov qab lub voj nrog lub hauv paus hloov hluav taws xob lossis lub koom haum rectifier Circuit Court.
7. Kho thiab ua kom zoo dua tus nqi ntawm cov damping resistor kom nws tsis tsim lub suab nrov thaum lub sijhawm tuag ntawm qhov hloov.
8. Tiv thaiv kev saturation ntawm EMI lim inductor.
9. Khaws cov ces kaum thiab cov khoom siv hluav taws xob thib ob kom deb ntawm cov khoom siv hluav taws xob los yog hloov lub raj cua sov.
10. Khaws lub viav vias nodes thiab cov khoom ntawm thawj lub cev hluav taws xob kom deb ntawm cov ntaub thaiv npog lossis lub dab dej kub.
11. Khaws cov khoom siv ntau zaus EMI cov ntxaij lim dej ze rau ntawm cov khoom siv cable lossis cov khoom siv txuas.
12. Khaws cov zis ntau zaus EMI cov ntxaij lim dej ze rau ntawm cov zis xaim terminals.
13. Khaws ib qho kev ncua deb ntawm cov ntawv ci tooj liab ntawm lub rooj tsav xwm PCB tawm tsam EMI lim thiab lub cev tiv thaiv.
14. Muab qee cov resistors rau ntawm txoj kab ntawm lub rectifier ntawm cov auxiliary coil.
15. Txuas damping resistors nyob rau hauv parallel nrog cov hlau nplaum bar kauj.
16. Txuas damping resistors nyob rau hauv parallel ntawm ob qhov kawg ntawm cov zis RF lim.
17. Tso cai rau 1nF / 500V ceramic capacitor lossis tseem muaj cov resistors thoob plaws qhov zoo li qub thiab pab windings ntawm thawj ntawm lub transformer hauv PCB tsim.
18. Khaws lub lim EMI kom deb ntawm lub hwj chim transformer; tshwj xeeb, tsis txhob muab tso rau hauv qhov kawg ntawm winding.
19. Yog hais tias thaj tsam PCB txaus, tso ib qho chaw ko taw ntawm PCB rau lub thaiv kev tiv thaiv windings thiab ib qho chaw rau RC damper, uas tuaj yeem txuas mus rau ob qho kawg ntawm cov shielding windings. Lub RC damper tuaj yeem txuas tau hla ob qhov kawg ntawm qhov thaiv qhov cua.
20. Yog tias qhov chaw tso cai, tso ib lub me me radial lead capacitor (Miller capacitor, 10 picofarads / 1 kV) ntawm qhov ntws thiab lub rooj vag ntawm lub zog hloov FET. Yog tias qhov chaw tso cai, tso ib lub me me radial lead capacitor (Miller capacitor, 10 pF / 1 kV) ntawm qhov ntws thiab lub rooj vag ntawm lub zog hloov FET.
21. Muab RC damper me me rau ntawm DC tso zis yog tias qhov chaw tso cai.
22. Tsis txhob tso lub qhov (socket) AC tiv thaiv lub dab dej kub ntawm lub raj hloov thawj zaug.
