Kwiminyaka yakutshanje, ngokutyhalela kwehlabathi ukungathathi hlangothi kwekhabhoni, ishishini elitsha lamandla-ingakumbi kwiindawo ezinjenge-photovoltaics, iibhetri, i-hydrogen electrolysis, kunye nokugcinwa kwamandla-lifumene ukukhula okugqabhukileyo. Lo mkhwa uzise iimfuno eziphezulu zobugcisa zezixhobo zokubonelela ngombane, kunye ne-IGBT-based (I-Insulated Gate Bipolar Transistor) elawulwayo yokuhlaziya i-rectifiers evelayo njengecandelo eliphambili kwizicelo ezibalulekileyo.
Xa kuthelekiswa ne-SCR yemveli (i-Silicon Controlled Rectifier) ehlaziyiweyo, izihlaziyi ze-IGBT zibonelela ngeenzuzo ezibalulekileyo ezifana nokusebenza okuhamba rhoqo, i-ultra-low output ripple, impendulo ekhawulezayo, kunye nolawulo oluchanekileyo. Ezi mpawu zibenza bafaneleke ngokukodwa kwizicelo ezifuna ukuzinza okungaqhelekanga kwangoku kunye nokulungelelaniswa ngokukhawuleza-okuqhelekileyo kumhlaba omtsha wamandla.
Kwicandelo lamandla e-hydrogen, umzekelo, iinkqubo ze-electrolysis yamanzi zifuna "umbane ophezulu wangoku, umbane ophezulu, kunye nemveliso eqhubekayo eqhubekayo." I-IGBT rectifiers ibonelela ngokuchanekileyo ngokuqhubekayo-ngoku, ukuthintela imiba efana nokushisa kwe-electrode kunye nokwehla kokusebenza kwe-electrolysis. Impendulo yabo eguqukayo ebalaseleyo ikwabavumela ukuba baziqhelanise neemeko zomthwalo oguquguqukayo kakhulu.
Ngokufanayo, kwiinkqubo zokugcina amandla kunye nezixhobo zokuvavanya ukukhutshwa kwebhetri, abahlaziyi be-IGBT babonisa ulawulo olubalaseleyo lokuhamba kwamandla amabini. Bangakwazi ukutshintsha ngaphandle komthungo phakathi kweendlela zokutshaja kunye nokukhupha, ukuphucula kakhulu ukusebenza kakuhle kwamandla kunye nokuthembeka kwenkqubo.
Ngokweengxelo zoshishino, ngo-2030, isabelo semarike ye-IGBT yokuhlaziya icandelo elitsha lamandla kulindeleke ukuba ibe ngaphezu kokuphindwe kabini-ingakumbi kumacandelo ombane ophakathi ukuya phezulu (njenge-800V nangaphezulu), apho imfuno ikhula ngokukhawuleza.
Okwangoku, uninzi lwabavelisi bombane basekhaya nakwamanye amazwe bagxile kwizinto ezintsha ezinxulumene ne-IGBT. Ezi nzame zibandakanya ukulungiswa kweesekethe zomqhubi, ukuphucula ukusebenza kwemodyuli yokupholisa, kunye nokuphuhlisa iinkqubo zokulawula ezikrelekrele ukuhambisa izixhobo zombane ezisebenza kakuhle, ezikrelekrele, nezithembekileyo.
Njengoko ubugcisa obutsha bamandla buqhubeka nokuvela, abahlaziyi be-IGBT abapheleli nje ekuboniseni inkqubela phambili yobugcisa kodwa bakwamiselwe ukuba badlale indima ebalulekileyo kutshintsho lwamandla kunye nokuqhubela phambili ubukrelekrele boshishino.
