Sesiphawule izikhathi ezingaphezu kwesisodwa ukuthi izinto zikagesi ziba βyikho konke kwethu.β Ama-elekthronikhi eselula, izimoto zikagesi, i-inthanethi yezinto, ukugcinwa kwamandla nokunye okuningi kuletha inqubo yokuphakelwa kukagesi nokuguqulwa kwamandla kagesi ezindaweni zokuqala ezibaluleke kakhulu kugesi. Ubuchwepheshe bokukhiqiza ama-chips kanye nezakhi ezihlukene usebenzisa izinto ezifana (GaN). Ngesikhathi esifanayo, akekho ozophikisana neqiniso lokuthi izixazululo ezididiyelwe zingcono kunezicacile zombili mayelana nokuhlangana kwezixazululo kanye nokonga imali ekuklanyeni nasekukhiqizeni. Muva nje, engqungqutheleni ye-PCIM 2019, abacwaningi abavela esikhungweni saseBelgian Imec ngokucacile ukuthi amandla e-single-chip (ama-inverter) asekelwe ku-GaN awawona neze inganekwane yesayensi, kodwa indaba yesikhathi esizayo esiseduze.
Besebenzisa i-gallium nitride kubuchwepheshe be-silicon kumawafa e-SOI (i-silicon ku-insulator), ochwepheshe be-Imec badale isiguquli se-single-chip half-bridge converter. Lokhu kungenye yezinketho ezintathu zakudala zokuxhuma ama-switch power (ama-transistors) ukuze udale ama-voltage inverters. Ngokuvamile, ukuze kusetshenziswe isifunda, kuthathwa isethi yezinto ezihlukene. Ukuze kuzuzwe ukubumbana okuthile, isethi yezakhi iphinde ifakwe ephaketheni elilodwa elivamile, elingaguquli iqiniso lokuthi isifunda sihlangene kusuka ezingxenyeni zomuntu ngamunye. AbaseBelgium bakwazile ukukhiqiza cishe zonke izakhi zebhuloho eliyingxenye yekristalu eyodwa: ama-transistors, ama-capacitors nama-resistors. Isixazululo senze kwaba nokwenzeka ukwandisa ukusebenza kahle kokuguqulwa kwe-voltage ngokunciphisa inani lezinto ze-parasitic ezivame ukuhambisana namasekhethi okuguqula.
Esifanekisweni esiboniswe engqungqutheleni, i-chip ye-GaN-IC ehlanganisiwe iguqule i-voltage engu-48-volt yokufaka ibe ivolthi ephumayo engu-1-volt enemvamisa yokushintsha engu-1 MHz. Isixazululo singase sibonakale sibiza kakhulu, ikakhulukazi uma kucatshangelwa ukusetshenziswa kwama-wafers e-SOI, kodwa abacwaningi bagcizelela ukuthi izinga eliphezulu lokuhlanganisa lingaphezu kokunciphisa izindleko. Ukukhiqiza ama-inverter kusuka ezingxenyeni ezihlukene kuzobiza kakhulu ngencazelo.
