Umphuhlisi waseBelgium uvula indlela yokubonelela ngombane "yetshiphu enye".

Siye saqaphela ngaphezu kwesihlandlo esinye ukuba izixhobo zombane ziba “yinto yethu yonke.” Ii-elektroniki eziphathwayo, izithuthi zombane, i-Intanethi yezinto, ukugcinwa kwamandla kunye nokunye okuninzi kuzisa inkqubo yobonelelo lwamandla kunye nokuguqulwa kombane kwezona zikhundla zibalulekileyo kwi-elektroniki. Itekhnoloji yokuveliswa kweetshiphusi kunye nezinto ezidityanisiweyo zisebenzisa izinto ezinje i-gallium nitride (GaN). Ngelo xesha, akukho mntu uya kuphikisa into yokuba izisombululo ezidibeneyo zingcono kunezo zicacileyo zombini ngokubhekiselele kwi-compactness of solutions kunye nokugcina imali kwi-design kunye nemveliso. Kutshanje, kwinkomfa ye-PCIM 2019, abaphandi abavela kwiziko laseBelgian Imec ngokucacileyo bonisileukuba izixhobo zombane zetshiphu enye (ii-inverters) ezisekwe kwi-GaN aziyonyani kwaphela, kodwa ngumcimbi wekamva elingekude.

Isebenzisa i-gallium nitride kubuchwepheshe be-silicon kwi-SOI (i-silicon kwi-insulator) ii-wafers, iingcali ze-Imec zenze i-single-chip half-bridge converter. Le yenye yeenketho ezintathu zakudala zokudibanisa iiswitshi zamandla (i-transistors) ukwenza ii-inverters zombane. Ngokuqhelekileyo, ukuphumeza isiphaluka, isethi yezinto ezicacileyo zithathwa. Ukufezekisa ukubumbana okuthile, isethi yezinto zifakwe kwiphakheji enye eqhelekileyo, engatshintshi into yokuba isiphaluka sihlanganiswe kumacandelo ngamnye. AmaBelgiya akwazi ukuvelisa phantse zonke izinto zebhulorho enesiqingatha kwikristale enye: i-transistors, i-capacitors kunye ne-resistors. Isisombululo senza ukuba sikwazi ukwandisa ukusebenza kakuhle kokuguqulwa kombane ngokunciphisa inani lezinto ze-parasitic ezihlala zihamba kunye neesekethe zokuguqula.

Kwiprototype eboniswe kwinkomfa, i-chip ye-GaN-IC edibeneyo iguqule i-voltage ye-48-volt ye-voltage kwi-voltage ye-voltage ye-volt kunye ne-frequency switching frequency ye-1 MHz. Isisombululo sinokubonakala sibiza kakhulu, ngakumbi ngokuqwalasela ukusetyenziswa kwee-wafers ze-SOI, kodwa abaphandi bagxininisa ukuba iqondo eliphezulu lokudibanisa ngaphezu kokunciphisa iindleko. Ukuvelisa ii-inverters ezivela kumacandelo ahlukeneyo kuya kuba yindleko ngakumbi ngenkcazo.
