Toshiba Smart Gate Drive Coupler TLP5214A/TLP5214/TLP5212/TLP5222 Daim ntawv qhia

Toshiba covSmart Gate Drive (SGD) coupler series, TLP5214A/TLP5214/TLP5212/TLP5222, yog tsim los kom tau raws li cov kev xav tau no. Cov couplers no tsis tsuas yog muaj VCE (sat) nrhiav kom tau muaj nuj nqi, Miller clamp muaj nuj nqi thiab FAULT tso zis muaj nuj nqi, tab sis kuj txais yuav 16-pin SO16L pob kom tau raws li qhov xav tau ntawm ntau yam, muab kev tiv thaiv kev tiv thaiv rau insulated rooj vag bipolar transistors (IGBTs) hauv inverter los ntawm overcurrent puas.

1. Khoom nta thiab kev ua haujlwm

Lub TLP5214A / TLP5214 / TLP5212 / TLP5222 series couplers muab kev tiv thaiv zoo rau IGBTs hauv kev siv inverter nrog lawv lub rooj vag ntse tsav tshuab. Kev tiv thaiv overcurrent muaj nuj nqi ntawm cov couplers tuaj yeem saib xyuas qhov ntws-qhov hluav taws xob (VDS) lossis cov khoom siv hluav taws xob hluav taws xob (VCE) ntawm lub tshuab hluav taws xob, thiab ua haujlwm muag muag thaum VDS lossis VCE nce los ntawm overcurrent raug kuaj pom, yog li tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj.

Tshwj xeeb yog qhov tseem ceeb yog tus qauv TLP5222, uas muaj kev tiv thaiv kev ua haujlwm tsis siv neeg rov ua haujlwm, uas tuaj yeem rov qab kho lub optocoupler mus rau lub xeev ua haujlwm li qub hauv 25.5μs (tus nqi raug) tom qab kev tiv thaiv kev ua haujlwm tau tshwm sim, ua kom yooj yim rau cov kab ke hauv cov maub los. . Tsis tas li ntawd, cov couplers no tseem koom ua ke ib qho kev ua txhaum ntawm lub xeev kev tawm tswv yim ua haujlwm, uas tuaj yeem xa cov teeb meem txhaum cai rau tus tswj xyuas thaum kuaj pom overcurrent, txhim kho cov lus teb ceev thiab kev ntseeg siab ntawm lub kaw lus.

Lub pob SO16L siv los ntawm TLP5222 ua kom muaj kev nkag mus deb thiab hluav taws xob tshem tawm ntawm 8 hli (tsawg kawg), ua rau nws tsim nyog rau cov khoom siv uas xav tau kev ua haujlwm zoo dua rwb thaiv tsev. Nyob rau tib lub sijhawm, nws qhov ntsuas kub ua haujlwm yog -40 degree rau 110 degree, ua rau nws haum rau ntau yam kev siv hauv qhov kub thiab txias, xws li cov tshuab hluav taws xob photovoltaic thiab cov khoom siv hluav taws xob tsis cuam tshuam (UPS).

2. Kev tiv thaiv overcurrent

Kev tiv thaiv overcurrent yog ib qho tseem ceeb hauv cov khoom siv hluav taws xob hluav taws xob uas pom qhov txawv txav tam sim no hauv Circuit Court thiab tiv thaiv kev puas tsuaj hauv Circuit Court. Qhov ua rau overcurrent tuaj yeem suav nrog qhov tso tawm luv luv thiab caj npab luv luv. Lub TLP5214A / TLP5214 / TLP5212 / TLP5222 series couplers muab kev tiv thaiv overcurrent los ntawm VCE (sat) saib xyuas thiab lwm txoj hauv kev los xyuas kom muaj kev nyab xeeb ntawm lub voj voog. Raws li pom hauv daim duab 1.1 (a) thiab daim duab 1.1 (b)

3. Kev piav qhia ua haujlwm ntawm SGD coupler

Lub SGD coupler saib xyuas lub collector-emitter voltage (VCE) ntawm IGBT thiab ua haujlwm los ntawm ob-theem kev tiv thaiv ib ntus nyob rau hauv cov ntaub ntawv ntawm overcurrent: thawj, mos-kaw VOUT los tiv thaiv IGBT los ntawm kev puas tsuaj los ntawm overcurrent, thiab tom qab ntawd xa mus txhaum teeb liab rau tus maub los. Qhov kev tiv thaiv no muaj ob txoj hauv kev rov pib dua, LED ua rau thiab rov pib dua tsis siv neeg, muab cov neeg siv nrog cov kev xaiv ua haujlwm hloov tau.

Hauv kev ua haujlwm ib txwm muaj, kev xa tawm thiab ntawm lub teeb liab LED cuam tshuam rau lub xeev ntawm DESAT tus pin thiab FAULT tso zis. Tsis tas li ntawd, SGD coupler muaj ib tug built-in active Miller clamp muaj nuj nqi uas txuas lub rooj vag-emitter ntawm IGBT, uas tuaj yeem clamp lub rooj vag yam tsis muaj cov khoom siv sab nraud, uas pab tiv thaiv luv luv Circuit Court nyob rau sab sauv thiab sab caj npab, yooj yim rau kev khiav lag luam. tsim, thiab txo qhov kev xav tau ntawm cov khoom siv hluav taws xob sab nraud. Raws li pom hauv daim duab 1.2 (a), Daim duab 1.2 (b), thiab daim duab 1.2 (c)

4. Cov ntawv thov

TLP5214A/TLP5214/TLP5212/TLP5222 series couplers yog haum rau ntau yam kev siv uas yuav tsum tau inverters, xws li inverters inverters, photovoltaic inverters, uninterruptible fais fab mov (UPS), roj teeb tswj systems (BMS), thiab lwm yam. cov couplers no ua rau lawv indispensable Cheebtsam nyob rau hauv cov kev siv no.
