Qhov zoo thiab kev faib tawm ntawm lub hwj chim adapter

(1) Qhov zoo ntawm lub hwj chim adapter

Fais fab adapter yog ib qho kev hloov pauv hloov hluav taws xob zoo li qub uas muaj cov khoom siv hluav taws xob semiconductor. Nws yog lub tshuab hloov hluav taws xob zoo li qub uas hloov lub zog zaus (50Hz) rau hauv nruab nrab zaus (400Hz ~ 200kHz) los ntawm thyristor. Nws muaj ob hom kev hloov pauv zaus: AC-DC-AC zaus hloov dua siab tshiab thiab AC-AC zaus hloov dua siab tshiab. Piv nrog rau cov khoom siv hluav taws xob ib txwm muaj, nws muaj qhov zoo ntawm kev tswj hwm kev hloov pauv, lub zog tso zis ntau, kev ua haujlwm siab, hloov pauv kev ua haujlwm yooj yim, tsis tshua muaj suab nrov, ntim me me, lub teeb yuag, yooj yim installation thiab ua haujlwm yooj yim thiab txij nkawm. Nws tau siv dav hauv cov khoom siv hauv tsev, metallurgy, kev tiv thaiv hauv tebchaws, railway, roj av thiab lwm yam lag luam. Lub hwj chim adapter muaj kev ua haujlwm siab thiab sib txawv zaus. Lub ntsiab thev naus laus zis thiab qhov zoo ntawm cov khoom siv hluav taws xob niaj hnub no yog raws li hauv qab no.

(2) Lub hom pib ntawm niaj hnub fais fab adapter txais qhov cheb zaus xoom voltage mos pib hom nyob rau hauv daim ntawv ntawm lwm yam excitation rau nws tus kheej excitation. Nyob rau hauv tag nrho cov txheej txheem pib, lub zaus tswj qhov system thiab tam sim no thiab voltage regulation kaw-voj system taug qab qhov kev hloov ntawm load txhua lub sij hawm kom paub txog qhov zoo tagnrho muag pib. Hom pib no muaj kev cuam tshuam me ntsis ntawm thyristor, uas yog qhov zoo rau kev ua haujlwm ntev ntawm lub thyristor. Nyob rau tib lub sijhawm, nws muaj qhov zoo ntawm kev pib yooj yim nyob rau hauv lub teeb thiab hnyav load, tshwj xeeb tshaj yog thaum cov hlau ua rauv tag nrho thiab txias, nws tuaj yeem pib tau yooj yim.

(3) Kev tswj xyuas Circuit Court ntawm niaj hnub fais fab adapter txais microprocessor tas li lub zog tswj Circuit Court thiab inverter Ф Lub kaum sab xis hloov kho tsis siv neeg tuaj yeem saib xyuas qhov kev hloov pauv ntawm qhov hluav taws xob, tam sim no thiab zaus txhua lub sijhawm thaum lub sijhawm ua haujlwm, txiav txim siab hloov pauv, hloov kho qhov hloov pauv ntawm lub zog hluav taws xob. Kev sib piv ntawm cov load impedance thiab qhov tso zis tsis tu ncua, kom ua tiav lub hom phiaj ntawm lub sijhawm txuag, txuag hluav taws xob thiab txhim kho lub zog. Nws muaj peev xwm txuag hluav taws xob thiab tsawg zog daim phiaj muaj kuab paug.

(4) Kev tswj xyuas hluav taws xob niaj hnub no yog tsim los ntawm CPLD software. Nws cov kev pab cuam input yog ua tiav los ntawm lub computer. Nws muaj lub siab pulse raug, tiv thaiv kev cuam tshuam, teb ceev ceev, yooj yim debugging, thiab muaj ntau yam kev tiv thaiv kev ua haujlwm xws li kev txiav tawm tam sim no, voltage txiav tawm, overcurrent, overvoltage, undervoltage thiab tsis muaj zog. Vim hais tias txhua yam khoom siv hluav taws xob ib txwm ua haujlwm nyob rau hauv qhov chaw nyab xeeb, lub neej kev pab cuam ntawm lub hwj chim adapter tau txhim kho zoo heev.

(5) Lub tshuab hluav taws xob niaj hnub tuaj yeem txiav txim siab theem theem ntawm peb-theem tuaj kab yam tsis muaj qhov txawv ntawm theem ntu ntawm a, B thiab C. qhov kev debugging yog yooj yim heev.

(6) Circuit Court boards ntawm niaj hnub fais fab adapters yog tag nrho cov tsim los ntawm yoj crest tsis siv neeg vuam, tsis muaj cuav welding. Txhua yam kev tswj hwm kev tswj hwm tau txais kev tswj xyuas hluav taws xob tsis sib cuag, tsis muaj qhov yuam kev, tsis tshua muaj qhov tsis ua haujlwm thiab ua haujlwm yooj yim heev.

(7) Kev faib tawm ntawm lub hwj chim adapters

Fais fab adapter tuaj yeem muab faib ua hom tam sim no thiab hom hluav taws xob raws li cov ntxaij lim dej sib txawv. Hom tam sim no yog lim los ntawm DC smoothing reactor, uas tuaj yeem tau txais DC tam sim no ncaj nraim. Lub load tam sim no yog lub voj voos, thiab qhov load voltage yog kwv yees li sine yoj; Hom hluav taws xob txais cov capacitor lim kom tau txais qhov ncaj ncaj DC voltage. Qhov hluav taws xob ntawm ob qho kawg ntawm lub load yog ib lub voj voos, thiab lub zog thauj khoom yog kwv yees li ntawm sine yoj.

Raws li lub load resonance hom, lub hwj chim adapter yuav muab faib ua parallel resonance hom, series resonance hom thiab series parallel resonance hom. Tam sim no hom yog feem ntau siv nyob rau hauv parallel thiab series parallel resonant inverter circuits; Voltage qhov chaw feem ntau yog siv nyob rau hauv series resonant inverter Circuit Court.
