Khoom nta ntawm High Frequency Switching Power Supplies
Cov khoom no txais yuav cov khoom lag luam txawv teb chaws thiab thoob ntiaj teb siab tshaj plaws-bridge inverter tam sim no converter technology precision ua, kom cov kev ua tau zoo ntawm tag nrho lub tshuab yog ruaj khov thiab zoo dua txhim khu kev qha.2 Tag nrho lub tshuab muaj tshaj-voltage, dhau-tam sim no. , over-temperature, luv-circuit, tsis muaj theem, xws li kev tiv thaiv tsis siv neeg thiab lub tswb muaj nuj nqi thiab muag muag ua haujlwm. Thiab tuaj yeem ntsia tau nrog lub sijhawm tswj thiab lub computer interface.3 DC tso zis waveform rau high-frequency square yoj, ripple coefficient ntawm "1 [%], tuaj yeem txhim kho tus naj npawb ntawm plating, tsis kam passivate, txhim khu lub gloss ntawm plated nto thiab plated pieces ntawm cov ces kaum tsaus nti ntawm cov tub ntxhais drilling degree Nws kuj tuaj yeem txo qhov poob ntawm cov ntaub ntawv raw thiab ua tau raws li ntau yam kev cai tshwj xeeb ntawm electroplating kev lag luam.4SFG series txais cov cua txias tsim, uas yooj yim rau nruab thiab nruab nrog cov chaw taws teeb tswj , yooj yim rau kev khiav lag luam Nws tuaj yeem hloov mus rau thiab tawm ntawm lub tshuab nrog kev thauj khoom, txo cov txheej txheem cumbersome ntawm kev tswj.5. thiab ua kom nws lub neej ua haujlwm ntev.6 Kev ua haujlwm siab, txuag hluav taws xob, kev ua haujlwm ua haujlwm tau nce mus txog ntau dua 90 [%], thiab qhov sib piv ntawm qhov ntsuas hluav taws xob tam sim no yeej ib txwm muaj kev sib tw ua kom txuag tau cov tsoos rectifier regulator thiab poob ntawm lub ntsiab transformer. kev txuag hluav taws xob ntau dua 35 [%], txo tus nqi plating zoo heev, kev lag luam kho saum npoo yog qhov kev xaiv zoo tshaj plaws!
Raws li txoj cai tswj hwm TRC, muaj peb txoj hauv kev:
Ua ntej, pulse width modulation (pulseWidthModulation, abbreviation) hloov lub sij hawm tas li, los ntawm kev hloov cov mem tes dav los hloov lub luag hauj lwm voj voog ntawm txoj kev. Thib ob, pulseFrequencyModulation (pulseFrequencyModulation, abbreviated li pFM) conduction pulse width yog tas mus li, los ntawm kev hloov pauv hloov kev khiav hauj lwm zaus hloov lub voj voog ntawm txoj haujlwm. Thib peb, sib xyaw modulation conduction mem tes dav thiab hloov zaus tsis tas, ib leeg tuaj yeem hloov txoj hauv kev, nws yog qhov sib xyaw ntawm ob txoj kev saum toj no. High-frequency switching fais fab mov tsis tas yuav ua rau kom qhov kev hloov pauv ceev tuaj yeem txo qis rau xoom hloov pauv, thiab lub suab nrov kuj yog me me.
