Uyilungisa njani i-pulse transformer kwisithando sokunyibilikisa induction?

Nokuba yi-pulse ye-rectifier (i-6 encinci ye-pulse transformer kwibhodi yokulawula) okanye i-inverter pulse (efakwe kwenye indawo, ngokuxhomekeke kwi-pulse pulse transformer esetyenziswa ukuchithwa kwesithando somlilo umenzi, kukho i-transformer enye okanye ii-transformers ezimbini kunye. Kwiibhodi zeesekethe ezincinci, kukho i-4 transformers kwibhodi yesiphaluka enye). Kodwa kukho i-diode ebomvu okanye eluhlaza ekhupha ukukhanya kwicala le-transformer nganye. Xa ukubetha kuqhelekile, ezi diode ziya kukhupha ukukhanya. Ngokuqinisekileyo, ngamanye amaxesha i-diode ekhupha ukukhanya ngokwayo iphukile.

Ke ngaba kuqinisekile ukuba ii-diode ezikhupha ukukhanya zikhanya ukubonisa ukuba i-pulse iqhelekile? impendulo ithi negative. Inxalenye yemveliso yezinye iisekethe ze-pulse ixhotyiswe ngeediode ezimbini, enye ifana nokulungiswa kwamaza esiqingatha ukubonelela phambili i-voltage ye-trigger kwi-thyristor, kwaye enye ibuyiselwe kwaye iqhagamshelwe kwi-terminal ephumayo ukukhawulela ukuphuma kwamandla ombane. Ukucinga ukuba i-diode yangaphambili esetyenziselwa ukulungiswa iphukile (i-circuit evulekileyo), i-voltage-limiting diode iyalungiswa, kwaye i-diode ekhupha ukukhanya isakhupha ukukhanya xa inombane ohamba phambili. Ngoko ke, i-diode ekhupha ukukhanya ayikwazi ukucacisa ngokuchanekileyo ukuba i-pulse transformer yonakalisiwe.

Kwimeko yokukhangela ingqibelelo yamanye amacandelo (ikakhulukazi i-thyristors), indlela yokugweba ukuba i-pulse ye-rectifier ilungile okanye ayikho: susa ucingo oluqhelekileyo lweengcingo ezintathu ze-inverter pulse kwibhodi yokulawula. Kwibhodi yokulawula uhlobo lweMPU-2, Vula iswitshi encinci No. 1 ebhodini ukuya kwelinye icala (cima isekethe yokutshayela), emva koko uvule unikezelo lwamandla ombane ophakathi ngokwenkqubo, vula i-potentiometer yamandla Iphaneli yomnyango ukuya kowona mgangatho uphezulu, kwaye ujonge ukuba amandla ombane e-DC yi-400～500V? Ukuba kunjalo, kuthetha ukuba i-rectifier circuit kuquka i-pulse yokuhlaziya iyinto eqhelekileyo; ukuba i-voltage ye-DC ayiqhelekanga okanye iphantsi kakhulu, susa amasango e-thyristor yokubuyisela enye kwaye uqaphele. Khumbula, ukuba i-thyristor ene-pulse eqhelekileyo isusiwe, I-voltage iya kuba ngaphantsi. Ukuba i-thyristor eyonakaliswe yi-pulse isusiwe, akukho mpendulo kwimitha, njengokungathi ucingo alususwanga, kuthetha ukuba kukho ingxaki kunye ne-pulse ehambelanayo. Susa ibhodi ye-pulse, ukuba kukho ii-diode ezimbini ekupheleni kokuphuma kwebhodi ye-pulse, i-solder enye isiphelo se-diode elandelayo, uze ulinganise ngokuchasana kwemitha yendalo yonke, kwaye ubeke indawo eyaphukileyo.
