Lilemong tsa morao tjena, ka ts'ebetso ea lefats'e ea ho se nke lehlakore ha carbon, indasteri e ncha ea matla-haholo-holo libakeng tse kang photovoltaics, libeteri, electrolysis ea hydrogen le polokelo ea matla-e bile le khōlo e matla. Mokhoa ona o tlisitse litlhoko tse phahameng tsa tekheniki bakeng sa lisebelisoa tsa phepelo ea motlakase, ka li-rectifiers tse laoloang ke IGBT (Insulated Gate Bipolar Transistor) tse hlahang e le karolo ea bohlokoa lits'ebetsong tsa bohlokoa.
Ha ho bapisoa le li-rectifiers tsa setso tsa SCR (Silicon Controlled Rectifier), li-rectifiers tsa IGBT li fana ka melemo ea bohlokoa joalo ka ts'ebetso ea maqhubu a holimo, molumo o phahameng o tlase haholo, karabelo e potlakileng, le taolo e nepahetseng. Likarolo tsena li li etsa hore li tšoanelehe haholo bakeng sa lits'ebetso tse hlokang botsitso bo ikhethang ba hajoale le ho lokisoa ka potlako - tse tloaelehileng tikolohong e ncha ea matla.
Ka mohlala, lefapheng la matla a haedrojene, litsamaiso tsa electrolysis tsa metsi li hloka “mahlaseli a phahameng a hona joale, a phahameng haholo le a tsitsitseng a tsoelang pele.” Li-rectifiers tsa IGBT li fana ka taolo e nepahetseng ea nako le nako, ho thibela litaba tse kang ho futhumala ha elektrode le ho theoha ha matla a motlakase. Karabelo ea bona e matla e matla e boetse e ba lumella ho ikamahanya le maemo a boima a fapaneng haholo.
Ka mokhoa o ts'oanang, lits'ebetsong tsa polokelo ea matla le lisebelisoa tsa tlhahlobo ea ho ntša betri, li-rectifiers tsa IGBT li bonts'a taolo e ikhethang ea phallo ea matla a mabeli. Ba khona ho chencha ka mokhoa o se nang moeli pakeng tsa mekhoa ea ho tjhaja le ea ho lahla, ho ntlafatsa haholo ts'ebetso ea matla le ts'epahalo ea sistimi.
Ho ea ka litlaleho tsa indasteri, ka 2030, karolo ea 'maraka ea li-rectifiers tsa IGBT lefapheng le lecha la matla e lebeletsoe ho feta habeli-haholo-holo likarolong tse bohareng ba motlakase (tse kang 800V le holimo), moo tlhokahalo e ntseng e eketseha ka potlako.
Hajoale, bahlahisi ba bangata ba phepelo ea motlakase malapeng le ba machabeng ba tsepamisitse maikutlo ho boqapi bo amanang le IGBT. Boiteko bona bo kenyelletsa ho ntlafatsa lipotoloho tsa bakhanni, ho ntlafatsa ts'ebetso ea pholileng ea module, le ho nts'etsapele lits'ebetso tsa taolo tse bohlale ho fana ka lisebelisoa tsa motlakase tse sebetsang hantle, tse bohlale le tse tšepahalang haholoanyane.
Ha mahlale a macha a matla a ntse a tsoela pele ho fetoha, lintlafatso tsa IGBT ha se sesupo sa tsoelopele ea tekheniki feela empa hape li ikemiselitse ho bapala karolo ea bohlokoa phetohong ea matla le nts'etsopele ea bohlale ba indasteri.
