Abashoferi b'irembo

Umushoferi w'irembo ni imbaraga zongerera imbaraga imbaraga zinjiza imbaraga ziva mumugenzuzi IC kandi ikabyara umuvuduko mwinshi winjira mumarembo ya transistor ifite ingufu nyinshi nka IGBT cyangwa MOSFET.Abashoferi b'irembo barashobora gutangwa haba kuri chip cyangwa nka module yihariye.Mubusanzwe, umushoferi w irembo agizwe nurwego ruhinduranya hamwe na amplifier.Umushoferi w'irembo IC akora nk'imbere hagati y'ibimenyetso byo kugenzura (sisitemu ya digitale cyangwa igereranya) hamwe na power power (IGBTs, MOSFETs, SiC MOSFETs, na GaN HEMTs).Ihuriro ryinjizwamo-shoferi rigabanya igishushanyo mbonera, igihe cyiterambere, fagitire yibikoresho (BOM), n'umwanya wibibaho mugihe bizamura ubwizerwe hejuru yubushakashatsi bwashyizwe mubikorwa.

Amateka

Mu 1989, International Rectifier (IR) yazanye ibicuruzwa bya mbere bya monolithic HVIC amarembo, ikoranabuhanga ryumuvuduko mwinshi w’umuzunguruko (HVIC) rikoresha ibikoresho byemewe bya monolithic bihuza bipolar, CMOS, hamwe nibikoresho bya DMOS byegeranye hamwe na voltage yamenetse hejuru ya 700 V na 1400 V yo gukora amashanyarazi ya offset ya 600 V na 1200 V. [2]

Ukoresheje ubu buryo buvanze-bwa tekinoroji ya HVIC, byombi byumuvuduko mwinshi urwego rwohinduranya imirongo hamwe na voltage ntoya hamwe na sisitemu ya digitale irashobora gushyirwa mubikorwa.Hamwe nubushobozi bwo gushyira umuzunguruko mwinshi cyane (mu iriba 'ryakozwe nimpeta ya polysilicon), rishobora' kureremba '600 V cyangwa 1200 V, kuri silikoni imwe kure yizindi zisigaye zumuriro muto, uruhande rwo hejuru. imbaraga MOSFETs cyangwa IGBTs zibaho mubintu byinshi bizwi cyane kumurongo wumuzingi wa topologiya nka buck, guhuza imbaraga, igice-ikiraro, ikiraro cyuzuye nicyiciro cya gatatu.Abashoferi b'irembo rya HVIC bafite ibyuma bireremba bikwiranye na topologiya isaba uruhande rwo hejuru, igice-kiraro, hamwe n'ibice bitatu.

Intego

Bitandukanye nabipolar transistors, MOSFETs ntisaba imbaraga zihoraho zinjiza, mugihe cyose zidafunguye cyangwa zizimye.Irembo ryitaruye-electrode ya MOSFET ikora aubushobozi(capacitori y amarembo), igomba kwishyurwa cyangwa gusohoka buri gihe MOSFET ifunguye cyangwa yazimye.Nka tristoriste isaba voltage yumuryango runaka kugirango ifungure, capacitori y irembo igomba kwishyurwa byibuze voltage yumuryango isabwa kugirango transistor ifungurwe.Mu buryo nk'ubwo, kugirango uzimye transistor, iki giciro kigomba gusaranganywa, ni ukuvuga ubushobozi bw irembo bugomba gusohoka.

Iyo transistor ifunguye cyangwa izimye, ntabwo ihita ihinduka kuva idakora ikajya muri leta ikora;kandi irashobora gushyigikira byimazeyo byumuvuduko mwinshi kandi ikayobora umuyaga mwinshi.Kubera iyo mpamvu, iyo irembo ryakoreshejwe kuri tristoriste kugirango ritume rihinduka, havuka ubushyuhe runaka bushobora, mubihe bimwe na bimwe, kuba bihagije gusenya transistor.Kubwibyo, birakenewe ko uhindura igihe gito gishoboka, kugirango ugabanyeGuhindura igihombo[de].Ibihe bisanzwe byo guhinduranya biri murwego rwa microseconds.Igihe cyo guhinduranya transistor iringaniza muburyo bwaikigezwehoyakoreshejwe mu kwishyuza irembo.Kubwibyo, guhinduranya ingendo akenshi bisabwa murwego rwijanamilliamperes, cyangwa ndetse no mu rwego rwaamperes.Kubisanzwe amarembo yumuriro hafi 10-15V, menshiwattsyimbaraga zirashobora gusabwa gutwara moteri.Iyo imigezi minini ihinduwe kuri frequency nyinshi, urugero muriGuhindura DC-Kuri-DCcyangwa bininimoteri y'amashanyarazi, tristoriste nyinshi rimwe na rimwe zitangwa muburyo bubangikanye, kugirango zitange imbaraga zihagije zo guhinduranya no guhinduranya imbaraga.

Guhindura ibimenyetso kuri tristoriste mubisanzwe bitangwa numuzunguruko cyangwa amicrocontroller, itanga ibimenyetso bisohoka mubisanzwe bigarukira kuri milliamperes nkeya zubu.Kubwibyo, tristoriste itwarwa neza nikimenyetso nk'iki cyahinduka gahoro gahoro, hamwe no gutakaza ingufu nyinshi.Mugihe cyo guhinduranya, capacitori y amarembo ya tristoriste irashobora gushushanya amashanyarazi byihuse kuburyo itera kurenza urugero mumuzunguruko wa logic cyangwa microcontroller, bigatera ubushyuhe bukabije butera kwangirika burundu cyangwa no gusenya burundu chip.Kugirango wirinde ko ibyo bitabaho, umushoferi wamarembo atangwa hagati yikimenyetso gisohoka cya microcontroller na power transistor.

AmashanyaraziByakoreshejwe inH-Ikiraromumashanyarazi maremare kumarembo atwara uruhande rwo hejuru n-umuyoboroimbaraga MOSFETSnaIGBTs.Ibi bikoresho bikoreshwa kubera imikorere myiza yabyo, ariko bisaba amarembo yo gutwara amarembo ya voltage nkeya hejuru ya gari ya moshi.Iyo hagati yikiraro cya kimwe cya kabiri kigenda hasi capacitor yishyurwa ikoresheje diode, kandi iki giciro gikoreshwa nyuma yo gutwara irembo ryuruhande rwo hejuru FET irembo rya volt nkeya hejuru yinkomoko cyangwa voltage ya emitter pin kugirango uyifungure.Izi ngamba zikora neza mugihe ikiraro gihora gihindurwa kandi kikirinda ingorane zo gukora amashanyarazi atandukanye kandi kikanemerera ibikoresho bya n-umuyoboro gukora neza gukoreshwa haba murwego rwo hejuru kandi ruto.
