Nekuda kwekuchinja kwehunhu hwekushandura simba rekuwisira, zviri nyore kukonzeresa switching Simba rekupa kugadzira huru electromagnetic kukanganiswa. Sekushandisa kwemagetsi mainjiniya, electromagnic kuwirirana injinjini, iwe unofanirwa kunzwisisa zvinokonzerwa nematambudziko elekomagnet. Chinyorwa ichi chinonyanya kuburitsa pfungwa huru dzekupa simba PCB Dhizaini.
15. Deredza iyo yekunyepedzera (inonzwa) chiratidzo chengozi nzvimbo uye chero nguva yakareba kuderedza kupindira.
. Panguva imwecheteyo, matunhu madiki emasaini anofanirwa kunge ari kure sezvinobvira kubva kune hombe di / dt chiratidzo chekudzivirira madonhukita emukati. Zviri nani kusaenda pasi peiyo hombe dv / dt chiratidzo kana chidiki chiratidzo chinotsvaga. Kana kumashure kwechiratidzo chidiki chiratidzo chesiratidzo chinogona kuvharwa (iyo ivhu rimwe chete), ruzha rwechiratidzo rwunoshanda kwauri runogona zvakare kudzikiswa.
17. Zviri nani kuisa pasi kutenderedza uye kumashure kweiyi hombe dV / dt signing trestiator (uye svutugadzike yekukwenenzvera. Izvi zvinogona kuderedza kupenya emi. Izvo zvinofanirwa kucherechedzwa kuti nzvimbo diki yechiratidzo hadzifanirwe kubatana nenzvimbo ino yekuchengetedza, neimwe nzira ichaunza kupindira kukuru. Yakakura DV / DT inoteedzera kazhinji inokweretesa yekuvhiringidza kune radiator uye padyo nepasi kuburikidza nekuwirirana nekuwirirana. Zvakanaka kubatanidza switch tube radiator kune iyo nzvimbo yekuvhara. Iko kushandiswa kwekusimuka-kwegomo kuchinjisa kuchinjisa kunodzikisawo kuenderana nekuwirirana, nekudaro kuderedza coupling.

21 Iyo pasi yekubatanidza nzira inoratidzwa mune inotevera dhizaini:
22. Kana ichivapo, tanga kutonga chimiro chevhu usati wabatanidza. Iyo ivhu rekusimudzira uye kukanganisa kwekurongedza kunowanzo kuve kwakabatana neiyo danda rakashata rezvakashata zvekunze, uye chiratidzo cheSampling chinowanzo bvunzwa kubva padanda rakanaka rezvakanaka zvekubuda. Iyo Diki chiratidzo Control Ground gadzi uye drive pasi inofanirwa kuve yakabatana neiyo e / s danda kana sampling upomeka switch chubhu ichinyatsotevedzera kudzivisa kuwanda kwekukanganiswa. Kazhinji kacho ivhu revhu uye drive pasi yeIC haina kutungamirwa kunze. Panguva ino, kutungamira kwekutadza kubva mukupokana kweanopokana kune iyo pasi pevhu kunofanirwa kunge kuri kudiki sezvinobvira kuderedza kupindira kwakazara kwekukanganiswa uye kunatsiridza kurongeka kwemasampuji azvino.
23. Iyo yekuburitsa voltage sampling network yakanakira kuve pedyo nekanganiso inoshamisira pane kune iyo yekubuda. Izvi zvinodaro nekuti masaini akaderera ekutadza haanyanye kukanganiswa kwekukomberedza kupfuura zvikwangwani zvakakwirira. Iyo sampling trawle inofanira kunge iri padyo sezvinobvira kune mumwe nemumwe kuti uderedze ruzha rwakatorwa.

27. Kana iyo yakakwira frequency chiratidzo yakaiswazve kune iyo yekuisa kutungamira, zviri nyore kuumba EMI (zvakajairika mode). Iwe unogona kuisa mhete yemagineti pane iyo yekuisa inotungamira padyo nePower Supply. Kana EMI yakaderedzwa, inoratidza dambudziko iri. Mhinduro yedambudziko iri ndeyekuderedza iyo coupling kana kuderedza iyo EMI ye dunhu. Kana iyo yakakwira-frequency ruzha haina kuiswa yakachena uye inoitwa kune iyo yekuisa kutungamira, EMI (yakasiyana maitiro) ichaumbwa. Panguva ino, mhete yemagineti haigone kugadzirisa dambudziko. Tambo mbiri dzakakwirira-dzinogara dzakakura Kuderera kunoratidza kuti dambudziko iri riripo. Mhinduro yedambudziko iri ndeyekuvandudza kusefa, kana kuderedza chizvarwa chechisere-frequency-frequency neruzha nekubudirana uye dzimwe nzira.
28. Kuyerwa kweMusiyanisa Mode uye Zvakafanana Mode iripo:
29 Iyo yaya inouya inovharidzirwa yakanyanya kuvharirwa neCassis pasi (nzira yacho sezvakatsanangurwa pamusoro). Iyo inobuda eEmifa yefaira inofanira kuitirwawo saizvozvo. Edza kuwedzera chinhambwe pakati pemutsara unouya uye iyo yakakwira DV / DT chiratidzo chinotsvaga, uye cherechedze icho mune chimiro.
