Yuav ua li cas cov kev ua kom muaj kev tiv thaiv cov zis ntawm cov cua tshuab thiab cov tshuab hluav taws xob ntawm kev nrawm nrawm?

, Cov kev sib tw tseem ceeb thiab DIode tiv thaiv logic hauv cov cua ceev
1. Cov yam ntxwv ntawm lub cev thiab cov kev pheej hmoo ntawm cov cua ceev
Cov zis hluav taws xob ntawm cov cua tshuab hluav taws xob yog ncaj qha rau peb lub zog thib peb ntawm cov cua ceev. Thaum cov cua ceev yog qis dua qhov txiav hauv cua ceev (feem ntau yog 3-5 m / s), thiab cov zis hluav taws xob yuav qis dua lub roj teeb lossis kev phom sij hauv qab no:

Cov thaub qab tam sim no: lub roj teeb lossis hluav taws xob cov khoom siv hluav taws xob hauv qab los ntawm lub cev muaj zog winding, ua rau lub cev muaj zog rau overheat thiab lub zog ruaj khov rau demagnetize;
Kev hloov pauv hloov pauv: tsis ruaj khov voltage ua rau kev ua haujlwm tsis txaus ntseeg ntawm cov DC / DC ntxiv lossis inverters;
Kev ua hauj lwm zoo: Lub zog Generation ua haujlwm nrawm nrawm nrawm, thiab yog tias kev tiv thaiv tsis muaj, lub kaw lus yuav tau haus hluav taws xob ntxiv rau kev siv hluav taws xob.
2. Tiv thaiv mechanism ntawm dodes
Diodes tsim kev sib cais ntawm lub cev ntawm kev sib cais los ntawm Unidirectional conductivity:

Kev Conduction rau pem hauv ntej: Thaum cov zis hluav taws xob ntawm lub tshuab hluav taws xob yog siab dua qhov kev ua haujlwm ntawm lub chaw tsim hluav taws xob, cov Diode ua thiab tam sim no ntws tawm ntawm lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob mus rau lub tshuab hluav taws xob rau lub tshuab hluav taws xob;
Rov qab Cutoff: Thaum lub tshuab hluav taws xob voltage qis dua li lub zog titter voltage, cov diode txiav tawm, thaiv qhov kev tam sim no.
Noj cov cua hlob me me ua piv txwv, nws li peb {{{{0} {}}}}}}}}}}} {, nrog voltage thib 1200v, tam sim no 604. Thaum cov cua nrawm yog qis dua 3m / s, cov diode array tuaj yeem thaiv cov hluav taws xob rov qab los ntawm lub tshuab hluav taws xob rau lub tshuab hluav taws xob, nrog kev tiv thaiv efficiency ntawm ntau dua 99.9%.

2, Cov Ntawv Thov Raug Raug Zoo thiab Kev Siv Kev Ua Haujlwm
1. Independent me - scale cua tshuab hluav taws xob
Hauv cov chaw taws teeb hluav taws xob, cua tshuab hluav taws xob me me (lub zog 1-10KW) feem ntau tau txais tshuaj "cua tshuab + roj teeb"|Architecture "architecture. Nws cov qauv tiv thaiv muaj ob txheej ntawm diodes:

Rectification Txheej: peb {-}}}}}}}} theem hluav taws xob hloov chaw tam sim no, thiab cov teeb meem Diode yuav tsum tau ntsib:
Thim rov qab withstand voltage ntau dua los yog sib luag rau 1.5 zaug lub ncov voltage ntawm lub tshuab hluav taws xob (piv txwv li} v diode tau xaiv rau 24V system);
Qhov nruab nrab tam sim no yog ntau dua los yog sib npaug rau 1.2 lub sij hawm qhov ntsuas ntawm lub tshuab hluav taws xob (yog tias 5A system siv 6a diode).
Anti Backflow txheej: Txuas schottky diodes (xws li MBR1045CT, v_f =0.4 v) nyob rau hauv kev tsav tsheb thaum ua kom muaj kev cia siab.
Cov ntaub ntawv: Nyob rau hauv lub nroog hluav taws xob muaj zog nyob hauv Africa, cua tsim ua raws li tau piav qhia saum toj no tseem tuaj yeem tso tawm ntawm cov cua nrawm ntawm 2m / s. Lub rov qab ntawm lub roj teeb yog txo los ntawm 0.5A rau 0a, thiab lub neej lub neej tau txuas ntxiv los ntawm peb zaug.

2. Daim phiaj sib txuas cua tshuab cua
Hauv MW theem sib txuas muaj cua sib txuas nrog cov cua tshuab, Dirode kev tiv thaiv yuav tsum tau ua ke nrog cov khoom siv hluav taws xob lub zog hluav taws xob kom ua tiav:

Tshuab Side Converter: Siv igbt + diode rov qab lub sijhawm qis dua lossis sib npaug nrog 100ns, kom tsis txhob rov qab tam sim no nyob rau hauv high- zaus hloov;
Daim phiaj sab converter: nruab cov TVs diodes (xws li DC npav thiab thaj chaw sib tw los ntawm xob laim los yog sib thooj;
UNLOADING Circuit Cours: Thaum cov cua ceev dhau yog qis dhau thiab cov khoom lag luam DC ntawm cov kev ua haujlwm, hloov lub zog ntau tshaj rau kev noj haus.
Cov ntaub ntawv: kev ntsuas tiag tiag los ntawm ib qho kev tawm tsam hnyav cua ua liaj ua teb ntawm 12% rau 2%, thiab lub zog hluav taws xob tau nce los ntawm 8%.

3, cov ntsiab lus tseem ceeb thiab xaiv cov hauv paus ntsiab lus
1. Tub ntxhais parameter txuam
Kev tso tawm siab zoo (v_f): cuam tshuam ncaj qha cuam tshuam. Lub v {{2} f ntawm silicon -} Kev} Kev} Kev Ntxi-based} Kev schottky desiodes yuav txo nws mus rau 0.2-0.4V. Hauv 100kW cua tshuab cua, siv schottky diodes tuaj yeem txo cov kev poob txhua xyoo los ntawm 12000 kWh.
Rov qab lub sijhawm rov qab (TRR): Hauv siab {{0 zaus} zaus hloov chaw ntawm cov xwm txheej lossis sib luag rau 50ns kom tsis txhob hloov chaw poob. Lub TRR ntawm kev rov ua haujlwm nrawm
Surge tam sim no nqa muaj peev xwm (i2fsm): nws yuav tsum tau npog lub siab hloov pauv tam sim no thaum pib cua pib}}}}}}}}}} thiab tsis ua tiav. Piv txwv li, 2mw cua tshuab yuav tsum xaiv ib daim diode nrog i2fsm ntau dua lossis sib npaug nrog 300 mus daws ntawm cov kev cuam tshuam ntawm lub zog sib thooj.
2. Xaiv cov phiaj xwm txhim kho zoo
Temperature compensation: In high-temperature environments (such as desert areas), the junction temperature of diodes may exceed 150℃, and high-temperature resistant models (such as AEC-Q101 certified devices) should be selected;
Kev tsim kho dua tshiab: tau txais n {{+1 backplecy, lub kaw lus tseem tuaj yeem tswj hwm ntau dua 80% ntawm cov zis muaj peev xwm thaum ib qho Diode poob;
Kev sib xyaw ua ke: kev sib xyaw ua ke (xws li IPM) siv diodes thiab mosfets / iGbts tau txais yuav cov kev tsis sib haum xeeb thiab txhim kho kev ntseeg tau.
