Ububiko bwa NPU: Guhitamo Byiza Kubikoresho bya elegitoroniki bigezweho

Muri iki gihe iterambere ryihuta mu nganda za elegitoroniki, gukomeza kunoza imikorere yibigize ni moteri yingenzi yo guhanga udushya. Niterambere ryimpinduramatwara muburyo bwa tekinoroji ya capacitori ya electrolytike, serivise ya NPU ikora polymer aluminium ikomeye ya electrolytike capacator, hamwe numutungo wamashanyarazi uruta iyindi hamwe nibikorwa byizewe, byahindutse ikintu cyiza mubikoresho byinshi bya elegitoroniki yo mu rwego rwo hejuru.

Ibiranga tekinike nibyiza byo gukora

Imiyoboro ya NPU ikoresha tekinoroji igezweho ya polymer, ihindura igishushanyo cya electrolytite gakondo. Ikintu cyamenyekanye cyane ni ukurwanya gukabije kurwego rwo kurwanya (ESR). Iyi ESR yo hasi yunguka byimazeyo porogaramu nyinshi: Icya mbere, igabanya cyane gutakaza ingufu mugihe ikora, kuzamura imikorere yumuzunguruko muri rusange. Icya kabiri, ESR yo hasi ituma ubushobozi bwo guhangana ningaruka zo hejuru. Urukurikirane rwa NPU rushobora kugera kuri 3200mA / r.ms kuri 105 ° C, bivuze ko mubunini bumwe, ubushobozi bwa NPU bushobora guhangana n’imihindagurikire ikomeye.

Uru ruhererekane rutanga ubushyuhe bwagutse (-55 ° C kugeza 125 ° C), butuma imikorere ihamye mubidukikije bitandukanye bikaze. Ubuzima bwa serivisi bwamasaha 4.000 butuma biba byiza mubikoresho byinganda na sisitemu ya elegitoronike isaba gukora igihe kirekire. Byongeye kandi, ibicuruzwa byujuje RoHS byuzuye, byujuje ubuziranenge bwibidukikije bwibicuruzwa bigezweho.

Igishushanyo mbonera no guhanga udushya

Imikorere isumba ubushobozi bwa NPU ituruka kubintu byabo byihariye byo gutoranya no gushushanya. Gukoresha polymer ikora nka electrolyte ikomeye ikuraho burundu ibibazo byumye bya electrolyte no kumeneka bikunze kugaragara mumashanyarazi gakondo ya electrolytike. Iyi miterere ihamye ntabwo itezimbere gusa kwizerwa ryibicuruzwa ahubwo inongera imbaraga zo guhangana no kunyeganyega no guhinda imashini, bigatuma ihitamo neza kubikoresho nkibikoresho bigendanwa hamwe na elegitoroniki yimodoka.

Igicuruzwa kirimo pisitori ya radiyo ifite igishushanyo mbonera cya 8mm z'uburebure na 11mm z'uburebure, byujuje ibisabwa mu gihe cyo kubungabunga umwanya wa PCB. Igishushanyo cyemerera ubushobozi bwa NPU guhuza imiterere yimiterere yumuzunguruko mwinshi, bigashyigikira cyane inzira iganisha kuri miniaturizasi yibicuruzwa bya elegitoroniki.

Porogaramu Yagutse

Nibikorwa byayo byiza, ubushobozi bwa NPU bukurikirana bigira uruhare runini mubice byinshi byingenzi:

Sisitemu ya elegitoroniki ya sisitemu: Sisitemu yo kugenzura ibikoresho bya elegitoronike igenda iba ingenzi mu binyabiziga bigezweho. Ubushobozi bwa NPU bukoreshwa mubice bigenzura moteri (ECUs), sisitemu yo gufasha abashoferi bateye imbere (ADAS), sisitemu yo infotainment yimodoka, nibindi bikorwa. Ubushyuhe bwo hejuru cyane hamwe nigihe kirekire cyo kubaho byujuje byuzuye ibisabwa byokwizerwa bya elegitoroniki yimodoka. Mu binyabiziga byamashanyarazi n’ibivange, ubushobozi bwa NPU nibintu byingenzi bigize sisitemu yo gucunga ingufu na sisitemu yo gutwara ibinyabiziga.

Ibikoresho byo gutangiza inganda: Muri sisitemu yo kugenzura inganda, ubushobozi bwa NPU bukoreshwa cyane muri PLC, inverter, drives ya servo, nibindi bikoresho. ESR nkeya yabo ifasha kugabanya gutakaza ingufu no kunoza imikorere ya sisitemu, mugihe ubushyuhe bwagutse butuma imikorere ihamye mubidukikije.

Ibikorwa Remezo by'itumanaho: Sitasiyo ya 5G, seriveri yikigo, nibindi bikoresho byitumanaho bisaba imikorere yibikorwa byinshi kandi byizewe. Ubushobozi bwa NPU bukora neza mubihe biri hejuru cyane, bigatanga ingufu zisukuye kandi zihamye kubitunganya, kwibuka, hamwe na chip ya neti, bigatuma 24/7 bidahungabana bikoresha ibikoresho byitumanaho.

Abaguzi ba elegitoroniki: Nubwo urukurikirane rwa NPU ari igicuruzwa cyo mu rwego rw’inganda, imikorere yacyo myiza yanatumye ikoreshwa mu bikoresho bimwe na bimwe byo mu rwego rwo hejuru bikoresha ibikoresho bya elegitoroniki, nk'imikino y’imikino, ibikoresho byerekana 4K / 8K, hamwe n’ibikoresho byo mu rwego rwo hejuru, bitanga uburambe bw’abakoresha.

Ibiranga inshuro hamwe nigishushanyo mbonera

Ubushobozi bwa NPU bufite imiterere yihariye yo gusubiza. Ubushobozi bwabo bwo gukosora bwerekana uburyo busanzwe kuri radiyo zitandukanye: 0.12 kuri 120Hz, buhoro buhoro bwiyongera buhoro buhoro, bugera kuri 1.0 kuri 100kHz. Ibiranga bifasha abashushanya umuziki guhitamo icyitegererezo gikwiye hashingiwe kumurongo wihariye wa progaramu no kunoza imikorere yumuzunguruko.

Ubushobozi bwa capacitance indangagaciro zitandukanye nabwo bugaragaza ibintu bitandukanye biranga inshuro zitandukanye: ibicuruzwa bifite ubushobozi buri munsi ya 47μF bifite ibintu byo gukosora 1.05 kuri 500kHz; ibicuruzwa hagati ya 47-120μF bikomeza guhora bikosora 1.0 hejuru ya 200kHz; nibicuruzwa birenga 120μF byerekana umurongo wihariye uranga umurongo mwinshi. Ibi bisobanuro birambuye biranga ibintu byingenzi byerekana igishushanyo mbonera.

Iterambere ry'ikoranabuhanga hamwe n'ibiteganijwe ku isoko

Mugihe ibikoresho bya elegitoronike bigenda byerekeza kumurongo mwinshi, gukora neza, no kwizerwa cyane, isoko ryisoko rya polymer ikora amashanyarazi akomeye ya electrolytike ikomeje kwiyongera. Ibicuruzwa bya NPU bihuza neza niki cyerekezo, kandi ibikoresho bya tekinike byujuje byuzuye ibisabwa nibikoresho bya elegitoroniki bigezweho kubikoresho bitanga amashanyarazi.

Hamwe niterambere ryihuse ryikoranabuhanga rigenda ryiyongera nka interineti yibintu, ubwenge bwubukorikori, hamwe no gutwara ibinyabiziga byigenga, ibyifuzo bya capacator zikora cyane bizagenda byiyongera. Imiyoboro ya NPU izakomeza kunoza imikorere, kongera ubushobozi bwa capacitance, no kwagura ubushyuhe, itanga ibisubizo birambuye kubikoresho bya elegitoroniki bizaza.

Guhitamo no gusaba ibyifuzo

Mugihe uhitamo imiyoboro ya NPU, injeniyeri bakeneye gutekereza kubintu byinshi: icya mbere, imbaraga za voltage ikora nibisabwa ubushobozi, byemeza neza igishushanyo mbonera; icya kabiri, impinduka zigezweho zisabwa, guhitamo icyitegererezo gikwiye ukurikije ibikorwa byukuri nibikorwa byinshyi; hanyuma, amaherezo yubushyuhe bwibidukikije, byemeza imikorere ihamye murwego rwubushyuhe bukora.

Mugihe utegura imiterere ya PCB, witondere ingaruka ziterwa no kwiyobora kandi ugabanye intera iri hagati yubushobozi n'umutwaro. Kubisabwa byihuta cyane, birasabwa guhuza ubushobozi buke buto-bushobozi kugirango bigabanye ESR na ESL. Byongeye kandi, igishushanyo mbonera gikwirakwiza kizafasha kuzamura ubuzima bwa capacitori no kwizerwa.

Incamake

Urutonde rwa NPU ruyobora polymer aluminium ikomeye ya electrolytike yerekana ubushobozi bugaragara mu iterambere rya tekinoroji ya capacitor, ikomatanya ibyiza bya capacitori ya aluminium gakondo hamwe n’imikorere isumba iyindi ya polymer. Ubushobozi bwabo buke bwa ESR, ubushobozi bugezweho bwubu, ubushyuhe bwagutse, nubuzima burebure butuma biba ingenzi mubikoresho bya elegitoroniki bigezweho.

Hamwe nogukomeza gutera imbere kwikoranabuhanga rya elegitoroniki, ubushobozi bwa NPU bukurikirana bizakomeza gutera imbere, butange ibisubizo byujuje ubuziranenge, byizewe by’ibikoresho bya elegitoronike mu nganda zinyuranye, byongera udushya mu ikoranabuhanga no kuzamura ibicuruzwa. Haba mubikoresho bya elegitoroniki, kugenzura inganda, cyangwa ibikoresho byitumanaho, ubushobozi bwa NPU buzagira uruhare runini mugutwara inganda za elegitoronike kugana kumikorere myiza no kwizerwa kurushaho.
