Takaona kanopfuura kamwe kuti magetsi ari kuita "zvese zvedu." Nharembozha dzemagetsi, mota dzemagetsi, iyo Internet yezvinhu, kuchengetedza simba uye zvimwe zvakawanda zvinounza maitiro ekupa magetsi uye kushandura magetsi kune ekutanga akakosha zvinzvimbo mumagetsi. Tekinoroji yekugadzira machipisi uye discrete zvinhu uchishandisa zvinhu zvakaita se (GaN). Panguva imwecheteyo, hapana anopokana nenyaya yekuti mhinduro dzakabatanidzwa dziri nani pane discrete dziri mbiri maererano nekubatana kwemhinduro uye maererano nekuchengetedza mari pakugadzira nekugadzira. Munguva pfupi yapfuura, pamusangano wePCIM 2019, vaongorori vanobva kuBelgian centre Imec zvakajeka kuti single-chip power supply (inverters) yakavakirwa paGaN haisi ngano yesainzi zvachose, asi inyaya yeramangwana riri pedyo.
Ichishandisa gallium nitride pasilicon tekinoroji paSOI (silicon pane insulator) mawafers, nyanzvi dzeImec dzakagadzira imwe-chip half-bridge converter. Iyi ndeimwe yemhando nhatu dzemhando yepamusoro dzekubatanidza magetsi switch (transistors) kugadzira voltage inverters. Kazhinji, kuita dunhu, seti yezvinhu zvakasarudzika inotorwa. Kuti uwane imwe compactness, seti yezvinhu inoiswawo mune imwe yakajairika package, iyo isingachinji chokwadi chekuti dunhu rakaunganidzwa kubva kune ega zvikamu. MaBelgians akakwanisa kubereka zvinenge zvese zvinhu zvehafu-bhiriji pane imwe kristaro: transistors, capacitors uye resistors. Mushonga wacho wakaita kuti zvikwanisike kuwedzera kushanda kwekushandurwa kwevoltage nekudzikisa huwandu hwezviitiko zveparasitic zvinowanzo perekedza maseketi ekushandura.
Mune prototype yakaratidzwa pamusangano, iyo GaN-IC chip yakasanganiswa yakashandura 48-volt yekuisa voltage kuita 1-volt inobuda voltage ine switching frequency ye1 MHz. Mhinduro yacho ingaite seyakadhura zvakanyanya, kunyanya tichifunga nezvekushandiswa kweSOI wafers, asi vaongorori vanosimbisa kuti iyo yakakwira dhigirii yekubatanidza inodarika mutengo. Kugadzira inverters kubva discrete components kuchave kunodhura netsanangudzo.
