Rooj Tsav Tsheb

Tus neeg tsav tsheb lub rooj vag yog lub tshuab hluav taws xob uas lees txais lub zog hluav taws xob qis los ntawm tus tswj hwm IC thiab tsim cov tswv yim tsav tam sim no rau lub rooj vag ntawm lub tshuab hluav taws xob siab xws li IGBT lossis lub zog MOSFET.Cov neeg tsav tsheb lub rooj vag tuaj yeem muab rau ntawm-chip lossis ua ib qho kev sib cais.Nyob rau hauv qhov tseeb, tus tsav lub rooj vag muaj ib theem shifter ua ke nrog lub amplifier.Lub rooj vag tsav tsheb IC ua haujlwm los ntawm kev sib txuas ntawm cov teeb liab tswj (cov digital lossis analog controllers) thiab lub zog hloov hluav taws xob (IGBTs, MOSFETs, SiC MOSFETs, thiab GaN HEMTs).Ib qho kev daws teeb meem ntawm rooj vag-tsav tsheb yuav txo qis kev tsim qauv, lub sijhawm txhim kho, daim nqi ntawm cov ntaub ntawv (BOM), thiab lub rooj tsavxwm qhov chaw thaum txhim kho kev ntseeg siab tshaj qhov kev daws teeb meem ntawm qhov rooj tsav tsheb.

Keeb kwm

Xyoo 1989, International Rectifier (IR) tau qhia thawj monolithic HVIC rooj vag tsav tsheb cov khoom, lub tshuab hluav taws xob sib xyaw ua ke (HVIC) siv patented thiab proprietary monolithic cov qauv kev sib xyaw ua ke bipolar, CMOS, thiab sab DMOS cov khoom siv nrog kev tawg voltages saum 700 V thiab 1400. V rau kev khiav hauj lwm offset voltages ntawm 600 V thiab 1200 V.[2]

Siv lub tshuab hluav taws xob sib xyaw HVIC no, ob qho tib si high-voltage theem-hloov circuits thiab qis-voltage analog thiab digital circuits tuaj yeem siv tau.Nrog lub peev xwm los tso cov hluav taws xob hluav taws xob ntau (hauv 'qhov dej' tsim los ntawm polysilicon rings), uas tuaj yeem ' ntab' 600 V lossis 1200 V, ntawm tib silicon deb ntawm qhov seem ntawm qhov hluav taws xob qis hluav taws xob, sab siab. hwj chim MOSFETs los yog IGBTs muaj nyob rau hauv ntau yam nrov off-line Circuit Court topologies xws li phaw, synchronous boost, ib nrab-bridge, tag nrho-bridge thiab peb-theem.Cov neeg tsav tsheb lub rooj vag HVIC nrog cov keyboards ntab yog qhov tsim nyog rau cov txheej txheem uas yuav tsum tau muaj kev siab siab, ib nrab choj, thiab peb theem teeb tsa.[3]

Lub hom phiaj

Nyob rau hauv sib piv raubipolar transistors, MOSFETs tsis tas yuav tsum muaj lub zog nkag mus tas li, tsuav yog lawv tsis raug hloov los yog tawm.Lub rooj vag sib cais-electrode ntawm MOSFET daim ntawv acapacitor(lub rooj vag capacitor), uas yuav tsum tau them los yog tawm txhua lub sij hawm lub MOSFET yog switched los yog tawm.Raws li ib tug transistor yuav tsum tau ib tug tshwj xeeb rooj vag voltage nyob rau hauv thiaj li yuav hloov mus rau, lub rooj vag capacitor yuav tsum tau them rau tsawg kawg yog qhov yuav tsum tau lub rooj vag voltage rau lub transistor yuav tsum tau switched.Ib yam li ntawd, txhawm rau hloov lub transistor tawm, qhov nqi no yuav tsum tau dissipated, piv txwv li lub rooj vag capacitor yuav tsum tau tawm.

Thaum lub transistor yog switched los yog tawm, nws tsis tam sim ntawd hloov los ntawm ib tug uas tsis yog-conducting mus rau ib tug conducting xeev;thiab tuaj yeem txhawb nqa ob qho tib si high voltage thiab ua qhov tam sim no siab.Yog li ntawd, thaum lub rooj vag tam sim no tau siv rau lub transistor kom nws hloov, qee qhov hluav taws xob tau tsim tawm uas tuaj yeem, qee zaum, txaus los rhuav tshem lub transistor.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua kom lub sijhawm hloov pauv kom luv li sai tau, thiaj li txo qishloov poob[de].Lub sij hawm hloov pauv yog nyob rau hauv thaj tsam ntawm microseconds.Lub sijhawm hloov ntawm lub transistor yog inversely proportional rau tus nqi ntawmtam sim nosiv los them lub rooj vag.Yog li ntawd, kev hloov tam sim no feem ntau xav tau nyob rau hauv ntau yam ntawm ntau puamilliamperes, los yog txawm nyob rau hauv ntau yam ntawmamperes.Rau qhov rooj vag voltages ntawm kwv yees li 10-15V, ob pebwattsntawm lub zog yuav tsum tau tsav lub hloov.Thaum cov hluav taws xob loj hloov ntawm cov khoom siv siab, xws li hauvDC rau DC converterslos yog lojhluav taws xob motors, ntau lub transistors qee zaum muab nyob rau hauv parallel, thiaj li muab txaus siab hloov tam sim no thiab hloov hluav taws xob.

Lub teeb liab hloov rau lub transistor feem ntau yog tsim los ntawm lub logic circuit lossis amicrocontroller, uas muab cov teeb liab tso zis uas feem ntau txwv rau ob peb milliamperes ntawm tam sim no.Yog li ntawd, ib tug transistor uas yog ncaj qha tsav los ntawm xws li ib tug teeb liab yuav hloov maj mam, nrog correspondingly siab zog poob.Thaum lub sij hawm hloov, lub rooj vag capacitor ntawm lub transistor yuav kos tam sim no sai heev uas nws ua rau ib tug tam sim no overdraw nyob rau hauv lub logic Circuit Court los yog microcontroller, ua rau overheating uas ua rau muaj kev puas tsuaj mus tas li los yog ua tiav kev puas tsuaj ntawm cov nti.Txhawm rau tiv thaiv qhov no los ntawm qhov tshwm sim, lub rooj vag tsav tsheb tau muab nruab nrab ntawm lub microcontroller tso zis teeb liab thiab lub zog transistor.

Charge twjfeem ntau siv nyob rau hauvH-Bridgesnyob rau hauv siab sab tsav tsheb rau lub rooj vag tsav lub siab sab n-channelzog MOSFETsthiabIGBTs.Cov khoom siv no yog siv vim lawv qhov kev ua tau zoo, tab sis yuav tsum muaj lub rooj vag tsav voltage ob peb volts saum lub hwj chim rail.Thaum qhov nruab nrab ntawm ib nrab choj mus qis, lub capacitor raug them los ntawm diode, thiab cov nqi no yog siv los tsav lub rooj vag ntawm sab siab FET rooj vag ob peb volts saum lub qhov los yog emitter tus pin qhov voltage thiaj li hloov nws.Cov tswv yim no ua haujlwm tau zoo yog tias tus choj hloov pauv tsis tu ncua thiab zam qhov tsis yooj yim ntawm yuav tsum tau khiav cov khoom siv hluav taws xob sib cais thiab tso cai rau cov khoom siv n-channel ua tau zoo dua los siv rau ob qho tib si siab thiab qis.
