Isigaba sesithathu se-thyristoramandlaumlawuliisebenzisa isekethe yedijithali ukuqalisa i-thyristor ukufezekisa umbane kunye nolawulo lwamandla.Imo yokulawula i-engile ye-Adopt i-voltage yesigaba, ulawulo lwamandla lunolawulo olusisigxina lwexesha kunye nolawulo lwexesha eliguqukayo ngeendlela ezimbini.
Umlawuli wamandla osetyenziswayo unokuhlangabezana ne-voltage yereferensi engachanekanga, ngeli xesha ukujonga ukulungelelanisa umlawuli wamandla kwimo yezandla, ngokuthe ngcembe ukwandisa imveliso.Jonga ukuba i-ammeter ikhula ngokulandelelana.Umthwalo ngaphandle koxinzelelo, umthwalo awunakongezwa.Kule meko, kufuneka sijonge ukuba unikezelo lwamandla, umthwalo, njl., luqhelekile.Ukongeza, kunokwenzeka ukuba udibane nesiganeko esingaqhelekanga sokusebenza, izizathu ezinokwenzeka ziphezulu kakhulu ubushushu be-ambient, i-overcurrent yomthwalo wexesha elide, njl.
Xa isilawuli samandla sisetyenziswa, siya kuvelisa ubushushu bangaphakathi.Nceda ufake ngokuthe nkqo kwaye ushiye isithuba kumacala omabini ukuphepha ukutshatyalaliswa kobushushu obubi kunye nomonakalo kumlawuli wamandla.Ibhokisi yokulawula kufuneka ibe ne-air convection vent.Faka imingxuma yokuphefumla okanye ukukhupha iifeni ezisekelwe kumgaqo osezantsi womoya oshushu.
Gwema ukufakwa kwiindawo ezinomswakama obunzima okanye i-asidi, i-alkali kunye neegesi ezidliwayo.Musa ukufaka kwindawo enobushushu obuphezulu okanye umoya ongekho mgangathweni.Okusingqongileyo - 10-45;Ukufuma kwe-Ambient: ngaphantsi kwe-90%RH(akukho ukujiya).Xa isilawuli samandla singasebenzi kangangeenyanga ezintathu, nceda uthuli umphezulu ngaphambi kokuba usebenze umatshini.Ukugcinwa rhoqo, uthuli, ungcoliseko lwe-oyile kunye nezinye izinto ezininzi zinokubangela ukujikeleza okufutshane.
Ukusebenza okuphezulu, akukho ngxolo yomatshini kunye nokunxiba, akukho ntlantsi, impendulo ekhawulezayo, ubungakanani obuncinci, ubunzima obulula njalo njalo.Isilawuli samandla sinepleyiti yokuqalisa, iradiyetha yobuchwephesha, ifyuzi, ifeni kunye nendlu.Umatshini unemisebenzi yonke yebhodi yokulawula.Ngokulawula ngokuchanekileyo i-voltage, yangoku, kunye namandla, umlawuli wamandla wenza ukuba ulawulo lobushushu oluchanekileyo kwaye, nge-algorithm yayo yolawulo lwedijithali ephucukileyo, ikhulisa ukusebenza kakuhle kokusetyenziswa kwamandla kunye nokugcina amandla.
Umgaqo-siseko wokulondoloza amandla womlawuli wamandla uqondwa kakuhle, njengezijikelezo zokufudumala zombane, ezilawula ukuvulwa nokuvalwa kombhobho wokufudumeza.Abaqhagamsheli be-Ac okanye i-slid state relays ziqhele ukusetyenziswa, kodwa zivuliwe kwaye zivaliwe ngelixa usebenza.Oku kuphindaphinda kuthe gqolo kwiqondo lobushushu elingaguqukiyo.
Umlawuli wamandla usebenzisa isekethe yedijithali ukuchukumisa i-thyristor ukuqonda umbane kunye nokulawulwa kwamandla.Ulawulo lwe-voltage luthatha imo yolawulo lokutshintsha kwesigaba, ulawulo lwamandla lwahlulwe lube lulawulo lwexesha elimiselweyo kunye nolawulo lwamandla exesha eliguquguqukayo.Ibhodi yokulawula ixhotyiswe nge-phase-locked loop synchronization circuit, isiqalo esicothayo kunye nokuyeka ngokukhawuleza emva kombane, ukufumanisa ukufudumala kwe-heat sink, ukhuseleko lwangoku lokunciphisa.
Ulawulo lwamandla lutshintsho lwesigaba oluvaliweyo amandlaumlawuli.Imveliso yokukhupha i-pulse inezinga eliphezulu le-symmetry kunye nokuzinza, kwaye ayitshintshi kunye nobushushu be-ambient.Akukho luhlengahlengiso lwe-pulse symmetry kunye nokunciphisa okufunekayo ngexesha lokusetyenziswa.Ukulungiswa kweempazamo jikelele kunokugqitywa ngaphandle kwe-oscilloscope.Isetyenziswa ngokubanzi kwiindawo ezahlukeneyo zemizi-mveliso yombane kunye nolawulo lwangoku.Ifanelekile kumthwalo ochasayo, umthwalo ongenisayo, icala eliphambili le-transformer kunye nazo zonke iintlobo zezixhobo zokulungisa.
