Kev tsom xam ntawm cov ntawv sau thiab ua haujlwm ntawm kev lim apf nquag

Lub Apf nquag lim module yog ib qho tseem ceeb ntawm kev tswj hwm zoo niaj hnub no cuam tshuam nrog kev ua kom zoo nkauj ntawm apf nquag lim thiab cov yam ntxwv ntawm txhua yam.

{. Kev Hloov Teeb Meem Hloov Khoom

Cov tub ntxhais ntawm lub apf nquag lim module yog lub zog hloov pauv hluav taws xob, uas feem ntau yog tsim raws li hauv qab no:

1. igbt choj caj ces: Txhua theem muaj ob lub igbts tsim ib nrab choj ntawm 8 - 20 cmz;
{{02. DC npav: electrolytic capacitor cov tsev txhab nyiaj yog sib xyaw ua ke nrog cov ripple high-zaus;
3.} Tus npliag Circuit Court: Rc Compitorption network txo qhov hloov pauv hloov chaw;
4.} cua sov dissipation system: lub substrate kub tsis tau muaj tsawg dua los yog sib npaug ntawm 85℃los xyuas kom meej lub luag haujlwm ntawm lub zog fais fab.

II {.} Kev Ua Chav Ua

Cov kev tswj hwm ntse ntawm cov Apf nquag lim cov ntawv sau muaj:

1. Main ControlT DSP: Ti0 Daim duab, muaj peev xwm sib npaug ntawm ntau dua lossis sib npaug ntawm kev ua kom muaj kev cuam tshuam ntau tshaj plaws theoretical calculations.
2.} harchonic nrhiav kom tau: synchronous sampling adc, {}} Point / lub limtiam los kuaj xyuas
{{03. PWM tiam: Raws li qhov chaw Vector kev hloov kho, lub qhov hloov ploj yog txo los ntawm 15%.
4.} Kev tiv thaiv Circuit Court: Ntau tiv thaiv nrog overcurrent (ntau dua los yog sib npaug ntawm 2 npaug

Iii {{. interfaces thiab ib pawg

Cov txheej txheem txhawb nqa rau APF (nquag siv fais fab lim) module muaj:

1.} Ct sensor: {{}}}}} cme khz ({} db)
{{{0} human-tshuab-tshuab interface: 7- nti kov screen, ua kom pom 21 lub sijhawm tiag tiag
3. Kev sib txuas lus interface: Dual Rs 485 +}} ethernet, txhawb iec61850
{{04. Fais Fab Module: {{85 - 264 vact), kev sib cais ntau dua lossis sib npaug rau 4kv
