Yuav ua li cas txhim kho kom ntseeg tau ntawm lub zog ntawm lub zog uas muaj kev lom zem?

一, tus tub ntxhais lub cev ntawm parallel dodes
1. Tam sim no nthuav dav thiab muaj feem sib npaug
Thaum lub peev xwm tam sim no ntawm ib lub raj yog tsis txaus, kev sib txuas sib txuas tuaj yeem tsoo lub hwj chim rau lub hwj chim. Piv txwv li, lub tshuab hluav taws xob tshiab ob lub pob zeb (ntawm - board charger) siv plaub 30a kev ua haujlwm ntawm Pcasitic Inductance yog tswj tsis pub dhau 2NH. Ua ke nrog 0.2 ω cement de actor, tam sim no kev sib txawv tam sim no nyob rau hauv qhov ntau kub<± 5%, and it has successfully passed AECQ101 certification. The key design points include:

Xaiv cov khoom siv: nyiam dua li VF (SERPERT tsawg dua lossis sib npaug rau 5s kev sib npaug zos yog 30% siab dua li 30% siab dua li downes downes.
Tam sim no sib koom tswj: Txuas 0.1 {- 0.5 ω Tam sim no sib koom ua ke cov xwm txheej tam sim no (thaum muaj peev xwm tswj hwm kev sib tw tam sim no hauv ± 2%.
Thermal Kev Tswj Xyuas: parallel spacing ntau dua los yog sib npaug nrog 520 pob + qhov kub ntxhov yog siv rau hauv cov kev kub ntxhov tam sim no lossis sib npaug nrog 110℃nyob rau hauv lub tsheb khiav haujlwm.
2. Redundant Ford - ywj pheej architecture
Cov kev tsim qauv sib txuas yuav ua tiav kev ua txhaum thiab kev nyab xeeb txog kev nyab xeeb margin. Cov ntawv thov raug muaj xws li:

Muaj Plc Fais Fab Module: tau txais ib lub raj txuas ntxiv los tiv thaiv tsis pub dhau 10 μ S tau ua tsis tiav, ua rau cov khoom ua haujlwm tseem ceeb ntawm cov khoom siv tseem ceeb.
Lub Zog Tshiab Lub Tsheb BMS: Los ntawm kev siv Dual TVs Diode Diode Dhuav Dua, lub 8kV surge txhaum tus nqi yog txo los ntawm 12% mus rau 0.3%. Shandong Aerospace Weineng lub hom phiaj thib ob nyob rau hauv packerilizes tso cai rau saib xyuas cov raj tam sim no los ntawm ib lub raj ntawm 40% thiab txuas ntxiv nws lub neej ua haujlwm los ntawm ntau dua ob zaug.
3. Mekas daws rau cov xwm txheej tshwj xeeb
Tsim cov qauv tshwj xeeb rau cov kev xav tau:

Cov chaw tiv thaiv kub photovoltagtaic Thaum ib pawg ntawm cov roj teeb hlwb yog obstructed, tus bypass Diode ua kom tsis txhob muaj cov kev kub nyhiab cov roj teeb kom hlawv tawm.
Rs485 interface kev tiv thaiv: Ob chav 18v voltage regulators yuav tsum txuas nrog thaum lub sijhawm 4.7 ω tam sim no txwv. Cov cuab yeej ntsuas kub coefficients (xws li BZX84C18L) yuav tsum tau nyiam kom ntseeg tau kev sib txuas lus ruaj khov.
2, plaub kauj ruam rau kev tsim qauv engineering
1. Ntaus Ntaus Xaiv
Cov ntaub ntawv siv tam sim no yuav tsum vf dispermation tsawg dua los yog sib npaug nrog kev sib tw ua kom nrawm (FJS)
Voltage stabilizing thov: yuav tsum muaj zener kam rau tsawg dua los yog sib npaug ± 2%. Piv txwv li, TVs diodes yuav tsum tau txheeb xyuas qhov tseeb ntawm cov tshuab hluav taws xob raug (xws li SMaj5.0a clamping vertage tsawg dua los yog sib npaug ntawm 7.8v).
Pob Matching: rau {- 247 pob (xws li c3d10060H) yog qhov sib npaug rau ntau dua lossis muaj kev sib luag rau 8 hli, uas yog 50% siab dua rau-220.
2. Thermal Pawg Tswjhwm
Cov qauv cua sov dissipation path tsim: tau txais ib qho kev sib xyaw ua cua sov thiab thermal conductive silicone roj, cov thermal kuj tuaj yeem txo mus rau 0.5℃/ w.
Kev Ntsuam Xyuas Kub: Ua ke NTC thermistor (xws li MF52 series), Tiag {1} Lub sijhawm tawm tswv yim ntawm cov ntaub ntawv kub txog BMS.
Cov ntaub ntawv sim teb: Siv ansys orizpak rau simulate kub faib nyob rau hauv tshav sov puas efficiency los ntawm 20% piv rau 12 hli sib nrug nrog 8 hli sib kis).
3. Kev tiv thaiv txoj kev ua haujlwm zoo
Cov lus txhib kev tiv thaiv: Nruab TVs diodes (xws li P6Ke36CA) txhawm rau txhawm rau hloov pauv hloov pauv, nrog lub sijhawm teb ntawm tsawg dua lossis sib npaug rau 1ns.
Cov zis kev lim: parallel ceramic cacacacitors (xws li 0.1
Circuit Court Rhuav Lub Cav: Txuas ib tus kheej rov qab fuse (pptc) hauv cov ceg ntoo sib dhos, nrog polyswitch lvr series, nrog ib lub sijhawm ua haujlwm tsawg dua lossis sib npaug li 5 vib nas this.
4. Cov qauv ntsuas kev ntsuas
Tag nrho cov chaw ntsuas hluav taws xob tag nrho: khiav tsis tu ncua rau 2 teev ntawm 1.5 zaug qhov ntsuas uas tam sim no los xyuas qhov kub tsawg dua lossis sib npaug rau 10 degree.
Huab Twv: Txheeb xyuas lub 1.5 zaug ntsuas cov txheej txheem tiv thaiv tam sim no, xws li simulating kub kev poob siab ntawm -40℃~ 150℃ntsuas).
EMC sim: Raws li IEC 61000-4-5 tus qauv, muaj peev xwm ntawm nrog nrog 8kv / 5ka Surge cuam tshuam.
3, Raug Kev Siv Ntawv Kev Ntsuam Xyuas Raug
Rooj plaub 1: DC Sab Kev Tiv Thaiv ntawm photovoltaic inverter
Qhov Yuav Tsum Tau: Qhov 1500v System xav tau kom muaj kev tawm tsam tam sim no ntawm 20ka nrog kev ua tau zoo ntawm ntau dua lossis sib npaug ntawm 98%.
Kev daws:

Rectifier: Taike Tianrun 1700V / 50A SIC DIODE (G3S750P) yog xaiv, nrog VF {=8 ns.
Kev Tiv Thaiv Surge: Toshiba HN1D05Fe TV Diode (Vr=400 v, IPP 05 ka).
Cov nyhuv: cov txheej txheem ua haujlwm tau zoo dua los ntawm 2%, kev tiv thaiv surge teb tsawg dua los yog sib luag rau 1ns, ntawv pov thawj los ntawm T ü v rheinland.
Rooj plaub 2: kev tsheb ciav hlau hloov mus
Qhov yuav tsum tau: 3300v system, hloov zaus 5kHz, yuav tsum tau tiv thaiv 100 {3 3}} Circuit Court tam sim no.
Kev daws:

Rectification Module: Taike Tianrun 3300V / 50A Sic Diode (G3S33050p), ifsm {4} Ka.
