Indlela yemarike yeemodyuli zamandla!

Indlela yemarike yeiimodyuli zamandla!

Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo lwetekhnoloji ye-elektroniki yamandla, ubudlelwane phakathi kwezixhobo zombane kunye nomsebenzi wabantu kunye nobomi buye basondela ngakumbi, kwaye izixhobo ze-elektroniki azinakwahlulwa kunikezelo lwamandla oluthembekileyo.Kwiminyaka yoo-1980, unikezelo lwamandla ekhompyuter lwaqonda ngokupheleleyo ukumodareyithwa kokutshintsha kombane., yakhokela ekugqibezeleni ukutshintshwa kombane wekhompyutha.Ngeminyaka yee-1990, ukutshintshelwa kombane kwangena kwiindawo ezahlukeneyo zezixhobo zombane nezombane.Iiswitshi ezilawulwa yinkqubo, unxibelelwano, izixhobo zovavanyo lombane, izixhobo zombane, kunye nolawulo lwezixhobo zombane ziye zasetyenziswa ngokubanzi.Ukutshintshela unikezelo lwamandla kukhuthaze ukutshintshela unikezelo lwamandla Uphuhliso oluKhawulezayo lobuchwepheshe.Ngoku, izicelo ezikrelekrele kumacandelo asakhulayo anje ngeTV yedijithali, i-LED, i-IT, ukhuseleko, uloliwe ohamba ngesantya esiphezulu, kunye neefektri ezikrelekrele nazo ziya kukhuthaza kakhulu uphuhliso lwentengiso yombane wokutshintsha.

Ukutshintshaimodyuli yonikezelo lwamandla sisizukulwana esitsha sokutshintsha imveliso yonikezelo lwamandla, ikakhulu esetyenziswa kwiinkalo ezininzi ezifana nezoluntu, ezemizi-mveliso nezomkhosi, kubandakanywa izixhobo zokutshintsha, izixhobo zokufikelela, unxibelelwano oluphathwayo, unxibelelwano lwe-microwave, ukuhanjiswa kwamehlo, iirutha kunye namanye amasimi onxibelelwano kunye nee-elektroniki zemoto, I-aerospace Linda.Ngenxa yeempawu zomjikelo omfutshane woyilo, ukuthembeka okuphezulu kunye nokuphuculwa kwenkqubo elula, ukusetyenziswa kweemodyuli ukwenza inkqubo yonikezelo lwamandla kuye kwenza ukusetyenziswa kombane wemodyuli ngakumbi nangakumbi.Ngokukodwa kwiminyaka yakutshanje, ngenxa yophuhliso olukhawulezayo lweenkonzo zedatha kunye nokukhuthazwa okuqhubekayo kweenkqubo zokunikezelwa kwamandla okusasazwa, izinga lokukhula konikezelo lwamandla emodyuli ligqithile kunikezelo lwamandla oluphambili.

Abanye abantu kwishishini bakholelwa ukuba ukuphindaphindwa okuphezulu kokutshintsha kombane ngumgaqo wophuhliso lwayo.Uphuhliso luqhubela phambili, kunye nezinga lokukhula kwamadijithi angaphezu kwamabini ngonyaka, ukuya kwicala lokukhanya, ubuncinci, ukubhitya, ingxolo ephantsi, ukuthembeka okuphezulu kunye nokuchasana nokuphazamiseka.

Ukutshintsha iimodyuli zokubonelela ngombane kunokwahlulwa zibe ngamacandelo amabini: AC/DC kunye neDC/DC.Isiguquli se-DC/DC ngoku senziwe imodyuli, kwaye itekhnoloji yoyilo kunye nenkqubo yokuvelisa sele ikhulile kwaye isemgangathweni ekhaya nakwamanye amazwe, kwaye yamkelwa ngabasebenzisi.Nangona kunjalo, i-modularization ye-AC / DC, ngenxa yeempawu zayo, ihlangabezana neengxaki ezinzima zobugcisa kunye nenkqubo yokuvelisa inkqubo kwinkqubo yokumodareyitha.Ukongeza, uphuhliso kunye nokusetyenziswa kokutshintsha kombane kubaluleke kakhulu ekongeni umbane, ukonga izixhobo kunye nokukhusela okusingqongileyo.

1. Ubuninzi bamandla abukho buphezulu, buphezulu kuphela

Ngokusetyenziswa ngokubanzi kwetekhnoloji ye-semiconductor, itekhnoloji yokupakisha kunye nokutshintsha okuthambileyo okukwi-high-frequency, ubuninzi bamandla ombane wemodyuli buba phezulu nangaphezulu, ukusebenza kakuhle koguqulo kuya kunyuka nangaphezulu, kwaye isicelo siya silula kwaye silula.Uguqulo olutsha lwangoku kunye neteknoloji yokupakisha inokwenza ubuninzi bamandla ombane bugqithise (50W / cm3), ngaphezu kokuphindwe kabini koxinzelelo lwamandla ombane wendabuko, kunye nokusebenza kakuhle kunokugqithisa i-90%.Ukusebenza ngokugqibeleleyo, kunye noxinano lwamandla olu-4x olungaphezulu kuneziguquli ezinokuthelekiswa ezikhoyo ngoku kwimarike, zenza iziseko zophuhliso lwamandla e-HVDC zisebenze kakuhle kwizicelo ezifana neziko ledatha, unxibelelwano kunye noshishino.

2. I-voltage ephantsi kunye nephezulu yangoku

Ngokuhla kwamandla ombane osebenzayo we-microprocessor, i-voltage ephumayo yobonelelo lwamandla emodyuli nayo yehla ukusuka kwi-5V yangaphambili ukuya kwi-3.3V yangoku okanye nakwi-1.8V.Ishishini liqikelela ukuba i-voltage ephumayo yonikezelo lwamandla nayo iya kuhla ngaphantsi kwe-1.0V.Ngexesha elifanayo, ikhoyo ngoku efunwa yisekethe edibeneyo iyanda, ifuna ukunikezelwa kwamandla ukunika amandla amakhulu okukhutshwa komthwalo.Kwimodyuli ye-1V / 100A unikezelo lwamandla ombane, umthwalo osebenzayo ulingana no-0.01, kwaye iteknoloji yendabuko kunzima ukuhlangabezana neemfuno zoyilo ezinzima.Kwimeko yomthwalo we-10m, ukuchasana kwe-m nganye kwindlela yomthwalo kuya kunciphisa ukusebenza kakuhle nge-10, kunye nokumelana nocingo lwebhodi yesekethe eprintiweyo, ukuchasana kochungechunge lwe-inductor, ukuchasana kwe-MOSFET kunye nokufa. iintambo zeMOSFET, njl.njl. zinefuthe.

Okwesithathu, itekhnoloji yolawulo lwedijithali isetyenziswa kakhulu

Imodyuli yombane wokutshintsha isebenzisa iteknoloji yokulawula umqondiso wedijithali (DSC) ukulawula ingxelo evaliweyo yonikezelo lwamandla, kwaye yenza unxibelelwano lwedijithali kunye nehlabathi langaphandle.Unikezelo lwamandla emodyuli kusetyenziswa itekhnoloji yolawulo lwedijithali yindlela entsha kuphuhliso lwexesha elizayo loshishino lonikezelo lwamandla emodyuli, kwaye kukho iimveliso ezimbalwa ngoku., Uninzi lweenkampani zobonelelo lwamandla emodyuli aziyiphathi itekhnoloji yonikezelo lwamandla emodyuli elawulwa ngokwedijithali.Abangaphakathi kwishishini bakholelwa ukuba kwizicelo ezininzi, imfuno yokuphucula ukusebenza kakuhle kwamandla iya kuqhuba imfuno yolawulo lwamandla e-ICs kunyaka olandelayo.Emva kweminyaka emininzi yophuhliso olucothayo, ulawulo lwamandla edijithali ngoku lungene kwinqanaba lophuhliso olukhawulezayo.Kwiminyaka eyi-10 ezayo, uphando olugxile kwiimveliso ezisebenza ngamandla kulindeleke ukuba luqhube ukwamkelwa kolawulo lwamandla edijithali kwizicelo ezifana nabaguquleli be-DC-DC.

Okwesine, imodyuli yamandla akrelekrele iqala ukufudumala

Imodyuli yamandla ehlakaniphile ayihlanganisi kuphela isixhobo sokutshintsha amandla kunye nesekethe yokuqhuba kunye.Ikwanayo neesekethe zokubona iimpazamo ezakhelwe ngaphakathi ezifana nokugqithisa, ukugqithisa kunye nokufudumeza, kwaye inokuthumela iimpawu zokubona kwi-CPU.Iqukethe i-high-speed and low-power die, i-optimized gate drive circuit kunye nesekethe yokukhusela ngokukhawuleza.Nokuba kwenzeka ingozi yomthwalo okanye ukusetyenziswa ngokungafanelekanga, i-IPM ngokwayo inokuqinisekiswa ukuba ayinakonakaliswa.Ii-IPM ngokuqhelekileyo zisebenzisa ii-IGBT njengezinto zokutshintsha amandla, kwaye zinezakhiwo ezidibeneyo ezinezinzwa zangoku ezakhelwe ngaphakathi kunye neesekethe zokuqhuba.I-IPM iphumelela ngakumbi nangakumbi kwiimarike ngokuthembeka kwayo okuphezulu kunye nokusebenziseka ngokulula, ngakumbi ilungele abaguquli bamaza omoya kunye nokubonelela ngombane ohlukeneyo wokuqhuba iinjini.Isixhobo sombane esifanelekileyo kakhulu.

Ukutshintsha iimodyuli zobonelelo lwamandla ziyaqhubeka nokuphucula ukudityaniswa kunye nobukrelekrele, kwaye ishishini likwazama ukubonelela ngokupakishwa koxinzelelo lwamandla aphezulu, kwaye iimodyuli zamandla ezikrelekrele nazo ziya kufezekisa uphuhliso olukhulu.Nangona imarike yonikezelo lwamandla okutshintshayo inamathuba anomtsalane, imarike yomgangatho ophezulu okwangoku ilawulwa ziimpawu zamazwe ngamazwe.Iimpawu zengingqi kufuneka ziqhubeke nokomeleza uyilo lweenkcukacha zemveliso, ulawulo lomgangatho, kunye nokuthembeka ukuze kuthotywe le marike inkulu.
