Toshiba Smart Gate Driver Couplers TLP5214A/TLP5214/TLP5212/TLP5222 Daim ntawv qhia

Toshiba covSmart Gate Tsav Tsheb (SGD) coupler series-TLP5214A, TLP5214, TLP5212, thiab TLP5222- yog tsim tshwj xeeb los ua kom tau raws li cov cai no. Cov couplers no tsis tsuas yog muaj VCE (sat) nrhiav pom, Miller clamping, thiab FAULT tso zis zog tab sis kuj siv 16-pin SO16L pob kom haum rau ntau qhov kev xav tau. Lawv muab kev tiv thaiv zoo rau Insulated Gate Bipolar Transistors (IGBTs) hauv inverters, tiv thaiv lawv los ntawm kev puas tsuaj overcurrent.

Raws li lub tuam txhab tsom mus rau siab -cov khoom siv hluav taws xob ua tau zoo, peb cov khoom lag luam tseem ceeb suav nrog photocouplers, digital capacitive isolators, solid-state relays, interface isolators, and driver isolators. Cov khoom lag luam no ua lub luag haujlwm tseem ceeb hauv kev hloov cov teeb liab, siab - teeb liab kis tau tus mob ceev, kev sib cais tsav, nrhiav kom pom kev nthuav dav, thiab siab -voltage kev nyab xeeb cais. Lawv ua kom pom kev ua tau zoo tshwj xeeb thiab kev ntseeg siab hauv cov ntawv thov xws li kev lag luam automation, cov khoom siv photovoltaic, thiab Battery Management Systems (BMS).

1. Khoom nta thiab kev ua haujlwm
Lub TLP5214A / TLP5214 / TLP5212 / TLP5222 coupler series siv lub rooj vag ntse tsav tsheb kom xa cov kev tiv thaiv zoo rau IGBTs hauv kev siv inverter. Lawv cov kev tiv thaiv overcurrent muaj nuj nqi txuas ntxiv saib xyuas cov cuab yeej hluav taws xob ntws tawm - qhov hluav taws xob (VDS) lossis cov khoom sib sau- emitter voltage (VCE). Thaum kuaj pom VDS lossis VCE nce vim overcurrent, nws ua rau lub kaw lus mos, yog li tiv thaiv lub zog ntawm kev puas tsuaj.

Tus qauv TLP5222 yog qhov tshwj xeeb tshaj yog rau nws cov tsim- hauv kev rov ua haujlwm tsis siv neeg tom qab muaj kev tiv thaiv. Nws tuaj yeem rov pib dua lub photocoupler rau ib txwm ua haujlwm li ntawm 25.5 µs (tseem) tom qab kev tiv thaiv kev tiv thaiv, ua kom yooj yim rau kev teeb tsa hauv cov maub los. Tsis tas li ntawd, cov kev sib txuas no sib koom ua ke kev ua txhaum lub xeev cov lus tawm tswv yim, xa cov teeb meem txhaum cai rau tus tswj xyuas thaum kuaj pom overcurrent, uas txhim kho cov lus teb ceev thiab kev ntseeg tau.

Cov pob SO16L siv los ntawm TLP5222 ua kom muaj qhov sib txawv ntawm qhov tob thiab hluav taws xob sib txawv ntawm 8 hli (tsawg kawg), ua rau nws tsim nyog rau cov khoom siv uas yuav tsum tau muaj kev ua haujlwm siab rwb thaiv tsev. Tsis tas li ntawd, nws qhov ntsuas kub ua haujlwm ntawm -40℃txog 110℃tso cai rau nws hloov mus rau ntau yam kev siv hauv qhov kub thiab txias, xws li cov tshuab hluav taws xob photovoltaic thiab Uninterruptible Power Supplies (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, tsim los xyuas qhov txawv txav tam sim no thiab tiv thaiv kev puas tsuaj hauv Circuit Court. Ua rau overcurrent tuaj yeem suav nrog cov zis luv luv thiab caj npab luv luv. Lub TLP5214A/TLP5214/TLP5212/TLP5222 coupler series muab kev tiv thaiv overcurrent, feem ntau los ntawm VCE (sat) saib xyuas, ua kom muaj kev ruaj ntseg Circuit Court. Qhov no yog qhia hauv daim duab 1.1(a) thiab daim duab 1.1(b).

3. Kev piav qhia ua haujlwm ntawm SGD Couplers
SGD coupler saib xyuas IGBT's collector-emitter voltage (VCE). Nyob rau hauv cov xwm txheej overcurrent, nws ua haujlwm los ntawm ob- theem tiv thaiv kab ke: ua ntej, nws maj mam tig tawm VOUT los tiv thaiv IGBT kev puas tsuaj los ntawm overcurrent; tom qab ntawd, nws xa cov teeb liab txhaum cai rau tus tswj. Qhov kev tiv thaiv no muaj ob txoj hauv kev rov pib dua, LED txhais thiab tsis siv neeg rov pib dua, muab cov neeg siv nrog kev xaiv ua haujlwm hloov tau.

Thaum lub sijhawm ua haujlwm ib txwm, tig lub teeb liab LED tawm thiab ua rau cuam tshuam rau lub xeev ntawm DESAT tus pin thiab FAULT tso zis. Ntxiv mus, SGD coupler suav nrog kev tsim- hauv Miller clamp muaj nuj nqi txuas ntawm IGBT lub rooj vag thiab emitter. Qhov no clamps lub rooj vag yam tsis tas yuav tsum tau cov khoom siv sab nraud, pab tiv thaiv luv luv Circuit Court nyob rau hauv siab - sab thiab qis - cov khoom siv fais fab, ua kom yooj yim tsim, thiab txo qhov xav tau rau sab nraud circuitry. Cov haujlwm no tau piav qhia hauv daim duab 1.2(a), Daim duab 1.2(b), thiab daim duab 1.2(c).

4. Cov ntawv thov
Lub TLP5214A / TLP5214 / TLP5212 / TLP5222 coupler series yog tsim rau ntau yam kev siv uas yuav tsum tau inverters, nrog rau kev lag luam inverters, photovoltaic inverters, Uninterruptible Power Supplies (UPS), thiab Battery Management Systems (BMS). Kev ua haujlwm siab thiab ntau yam ntawm cov couplers no ua rau lawv cov khoom tseem ceeb hauv cov ntawv thov no.

Peb photocouplers thiab digital isolators, tshwj xeeb tshaj yog cov neeg tsav tsheb cais, tuav tus nqi tseem ceeb hauv cov teb no. Lawv tsis tsuas yog muab cov teeb liab sib kis tau zoo thiab kev sib cais kev nyab xeeb tab sis kuj txhawb kev tsim daim ntawv thov kev ua kom zoo, txo cov nqi tag nrho thiab kev nyuaj. Tsis tas li ntawd, kev ntseeg siab ntawm peb cov khoom siv - xeev relays ua rau lawv tshwj xeeb tshaj yog nyob rau hauv siab -voltage scenarios, xws li cov khoom siv hluav taws xob thiab cov chaw sib txuas lus.
