Chifukwa cha kusintha kwa magetsi osinthira, ndikosavuta kuyambitsa mphamvu yosinthira mphamvu kuti apange zododometsa zabwino za electromagnetic. Monga injiniya wamagetsi, mainjiniya ophatikizika, kapena mainjiniya a PCB, muyenera kumvetsetsa zomwe zimayambitsa chifukwa cha zovuta za electromagnetic ndipo mwatsimikiza, makamaka mainjiniya ayenera kudziwa kukula kwa malo onyansa. Nkhaniyi imayambitsa mfundo zazikuluzikulu za kapangidwe ka magetsi PCB.

.

. Nthawi yomweyo, zizindikiritso zazing'ono ziyenera kukhala kutali kwambiri ndi mizere yayikulu ya di i / DT siginecha kuti isalepheretse ma crosstalk. Ndikwabwino kuti musamapite pansi pa chikwangwani chachikulu dv / dt pomwe pali zizindikiro zazing'ono. Ngati kumbuyo kwa kayendedwe kakang'ono kamatha kukhazikika (malo omwewo), chizindikirochi chikuphatikizidwa kuti chithanso kuchepetsedwa.

. Izi zimatha kuchepetsera EMI. Tiyenera kudziwa kuti nthaka yaying'ono yaying'ono siyenera kulumikizidwa ndi malo otetezedwa awa, apo ayi adzayambitsa kusokonekera kwakukulu. Great DV / DT nthawi zambiri amalowererapo ku radiator ndi nthaka yapafupi kudzera pamavuto. Ndi bwino kulumikiza ma switrator a tube kupita ku malo otetemera. Kugwiritsa ntchito mapiri apaulendowo kumachepetsa mphamvu yolimbitsa thupi, potero kuchepetsa kulumikizana.

.

. Itha kuganiziridwa mu kapangidwe kake.

20. Pofuna kupewa zomwe zingasokoneze, gwiritsani ntchito mfundo imodzi ndi mphamvu kuchokera kumodzi.

. Njira yolumikizira pansi imawonetsedwa mu chithunzi chotsatira:

22. Pakukhazikitsa, woweruza woyamba umunthu usanalume. Nthaka yopangira zitsanzo ndi zopyola nthawi zambiri imayenera kulumikizidwa ndi mtengo woyipa wa pampacitor, ndipo chizindikiro cha zitsanzozo nthawi zambiri chimayenera kuchotsedwa pa mtengo wake wa Itacitor. Malo owongoletsera ang'onoang'ono ndi malo okwera nthawi zambiri amayenera kulumikizana ndi a E / S Nthawi zambiri malo olamulira ndikuyendetsa nthaka kuti ichotsedwe payokha. Pakadali pano, kutsogolera kutsogolera kuchokera ku Sampling ndi nthaka kuyenera kukhala kochepa kwambiri momwe mungathere kuchepetsedwa kusokoneza kosavuta ndikuwongolera kulondola kwa zitsanzo zomwe zikuchitika.

23. Kutulutsa kwamphamvu kwa matrating Izi ndichifukwa choti zizindikiro zotsika zimachitika sizingachitike kuposa kusokoneza kuposa zizindikiro zapamwamba. Maulendo a Sampling ayenera kukhala pafupi kwambiri ndi wina ndi mnzake kuti achepetse phokoso.

.

.

26. Kusambira kocheperako nthawi zambiri kumakhala kosiyana (pansipa 1M), ndipo kusokonezedwa kwapafupipafupi nthawi zambiri kumakhala njira wamba, nthawi zambiri kumaphatikizidwa ndi ma radiation.

. Mutha kuyimitsa mphete zamatsenga pa zomwe zimapangitsa kuti zikhale pafupi ndi magetsi. Ngati EMI ikuchepetsedwa, ikuwonetsa vuto ili. Njira yothetsera vutoli ndikuchepetsa kulumikizana kapena kuchepetsa emsi yadera. Ngati phokoso lalitali kwambiri silinasesa kutsukidwa komanso kuchitidwa kutsogolera, EMI (mosiyanasiyana) idzapangidwanso. Pakadali pano, mphete yamatsenga siyingathetse vutoli. Chingwe chachiwiri chambiri kwambiri (Symmetrical) komwe kuwongolera kumayandikira kwa magetsi. Kuchepa kumawonetsa kuti vutoli lilipo. Njira yothetsera vutoli ndikusintha zosefera, kapena kuchepetsa msinkhu wa phokoso lalitali lazosangalatsa.

28. Kuyeza kwa njira yosiyanirana ndi njira wamba pakalipano:

. Waya wobwera bwino ndi Chasis Ground (njira ndi monga tafotokozera pamwambapa). Zosefera EMI ziyenera kuchitidwa chimodzimodzi. Yesani kuwonjezera mtunda pakati pa mzere wobwera ndi DV / DT chizindikiro, ndipo muziganizira za kukomoka.
