Eminyakeni yamuva nje, njengoba umhlaba wonke uqhubeka nokungakhethi hlangothi kwekhabhoni, imboni entsha yamandla—ikakhulukazi ezindaweni ezifana ne-photovoltaics, amabhethri, i-hydrogen electrolysis, kanye nokugcinwa kwamandla—ibe nokukhula okukhulu. Lo mkhuba ulethe izidingo zobuchwepheshe eziphakeme zemishini yokuphakelwa kukagesi, kanye nama-rectifier alawulwa yi-IGBT (Insulated Gate Bipolar Transistor) avela njengengxenye ebalulekile ekusetshenzisweni okubalulekile.
Uma kuqhathaniswa nama-rectifier endabuko e-SCR (Silicon Controlled Rectifier), ama-rectifier e-IGBT anikeza izinzuzo ezibalulekile njengokusebenza kwemvamisa ephezulu, i-ultra-low output ripple, impendulo esheshayo, kanye nokulawula okunembile. Lezi zici ziwenza afaneleke kakhulu ezinhlelweni zokusebenza ezidinga ukuzinza kwamanje okungavamile kanye nokulungiswa okusheshayo—okuvamile endaweni entsha yamandla.
Emkhakheni wamandla e-hydrogen, isibonelo, izinhlelo ze-electrolysis zamanzi zidinga "ugesi ophezulu, i-voltage ephezulu, kanye nomkhiqizo oqhubekayo ozinzile." Ama-rectifier e-IGBT ahlinzeka ngokulawula okunembile kwe-constant-current, okuvimbela izinkinga ezifana nokushisa ngokweqile kwe-electrode kanye nokwehla kokusebenza kahle kwe-electrolysis. Impendulo yawo enhle kakhulu eguquguqukayo ibuye iwavumele ukuthi azivumelanise nezimo zomthwalo eziguquguqukayo kakhulu.
Ngokufanayo, ezinhlelweni zokugcina amandla kanye nemishini yokuhlola ukushaja nokukhipha ibhethri, ama-rectifier e-IGBT abonisa ukulawula okuvelele kokugeleza kwamandla okuqondiswa kabili. Angashintsha kalula phakathi kwezindlela zokushaja nokukhipha ibhethri, okuthuthukisa kakhulu ukusebenza kahle kwamandla kanye nokuthembeka kohlelo.
Ngokusho kwemibiko yemboni, ngo-2030, isabelo semakethe sama-rectifier e-IGBT emkhakheni omusha wamandla kulindeleke ukuthi siphindwe kabili—ikakhulukazi ezindaweni ezimaphakathi kuya kweziphezulu zamandla kagesi (njenge-800V nangaphezulu), lapho isidingo sikhula khona ngokushesha.
Njengamanje, abakhiqizi abaningi bamandla kagesi basekhaya nakwamanye amazwe bagxile ezintweni ezintsha ezihlobene ne-IGBT. Le mizamo ifaka phakathi ukwenza ngcono amasekethe omshayeli, ukuthuthukisa ukusebenza kokupholisa amamojula, kanye nokuthuthukisa izinhlelo zokulawula ezihlakaniphile ukuze zilethe izinsiza zamandla ezisebenza kahle, ezihlakaniphile, nezithembekile.
Njengoba ubuchwepheshe obusha bamandla buqhubeka nokukhula, ama-rectifier e-IGBT awagcini nje ngokubonisa intuthuko yezobuchwepheshe kodwa futhi ahlelelwe ukudlala indima ebalulekile ekushintsheni kwamandla kanye nokuthuthuka kobuhlakani bezimboni.
