Kev txhim kho ntawm kev hloov pauv tswj cov khoom siv hluav taws xob
Kev txhim kho ntawm kev hloov pauv tswj cov khoom siv hluav taws xob
Peb theem kev txhim kho tseem ceeb ntawm kev hloov hluav taws xob tswj hluav taws xob:
Thawj theem yog kev txhim kho cov khoom siv hluav taws xob semiconductor los ntawm cov khoom siv hluav taws xob bipolar (BpT, SCR, GT0) rau MOS cov khoom siv (lub zog MOS-FET, IGBT, IGCT, thiab lwm yam), ua rau lub zog hluav taws xob hauv hluav taws xob rau ua tiav high-frequency, txo qhov conduction poob, thiab ua kom yooj yim circuits.
Qhov thib ob theem pib nyob rau hauv 1980s, nrog rau kev tshawb fawb thiab kev loj hlob ntawm high-frequency thiab soft switching technologies, ua rau lub zog ua tau zoo dua, sib dua, thiab me me. High zaus thiab mos hloov tshuab tau yog ib qho ntawm cov ntsiab lus kub hauv kev lag luam hluav taws xob hluav taws xob thoob ntiaj teb hauv 20 xyoo dhau los.
Qhov thib peb theem pib nyob rau hauv nruab nrab-1990s, nrog rau kev txhim kho ntawm kev sib xyaw fais fab hluav taws xob tshuab hluav taws xob thiab kev sib txuas hluav taws xob hluav taws xob hluav taws xob (IpEM) thev naus laus zis, uas yog ib qho teeb meem tshiab uas yuav tsum tau daws sai sai hauv lub zog hluav taws xob thoob ntiaj teb. zej zog hnub no.
Kev faib tawm ntawm cov khoom siv hluav taws xob hloov pauv
1. Raws li kev tsav tsheb ntawm kev hloov pauv hloov lub raj, nws tuaj yeem muab faib ua tus kheej zoo siab thiab cais hom zoo siab. Qhia synchronous signals nyob rau hauv lub hauv paus ntawm nws tus kheej zoo siab tuaj yeem tsim ib lub synchronous switching voltage stabilizing circuit.
2. Raws li txoj kev tswj ntawm qhov voltage stabilization, nws tuaj yeem muab faib ua pulse width modulation type thiab pulse zaus modulation type, los yog kev sib xyaw ntawm ob los ua ib hom kev sib xyaw ua ke.
3. Raws li cov qauv ntawm cov hluav taws xob hloov hluav taws xob, lawv tau muab faib ua cov kauj ruam-down, kauj ruam-up, thim rov qab, thiab transformer hom.
Qhov zoo thiab qhov tsis zoo ntawm kev hloov hluav taws xob tswj hluav taws xob
Qhov zoo: Tsawg zog noj thiab ua haujlwm siab.
Disadvantage: Muaj kev cuam tshuam loj ntawm kev hloov pauv.
