DC DC converter

Feem ntau DC-DC converters yog tsim los rau unidirectional hloov dua siab tshiab, thiab lub hwj chim tsuas yog ntws los ntawm input sab mus rau sab tso zis.Txawm li cas los xij, lub topology ntawm tag nrho cov hloov hluav taws xob hloov hluav taws xob tuaj yeem hloov mus rau kev hloov pauv bidirectional, uas tuaj yeem tso cai rau lub zog ntws rov qab los ntawm cov zis sab nraud mus rau sab tswv yim.Txoj hauv kev yog hloov tag nrho cov diodes rau nws tus kheej tswj kev ua haujlwm rectification.Lub bidirectional converter yuav siv tau nyob rau hauv tsheb thiab lwm yam khoom uas yuav tsum tau regenerative braking.Thaum lub tsheb khiav, lub converter yuav muab lub zog rau lub log, tab sis thaum braking, lub log yuav muab lub zog rau lub converter tig.

Kev hloov pauv hloov pauv yog qhov nyuaj dua los ntawm kev xav ntawm cov khoom siv hluav taws xob.Txawm li cas los xij, vim tias ntau lub voj voog tau ntim rau hauv kev sib xyaw ua ke, yuav tsum muaj tsawg dua.Hauv kev tsim hluav taws xob hluav taws xob, txhawm rau txo cov suab nrov hloov pauv (EMI / RFI) mus rau qhov tso cai ntau thiab ua kom lub zog hluav taws xob muaj zog ua haujlwm ruaj khov, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo tsim lub voj voog thiab cov txheej txheem ntawm cov khoom siv hluav taws xob thiab cov khoom siv.Yog hais tias nyob rau hauv daim ntawv thov ntawm kauj ruam-down, tus nqi ntawm kev hloov converter yog siab dua li ntawm linear converter.Txawm li cas los xij, nrog kev nce qib ntawm kev tsim chip, tus nqi ntawm kev hloov pauv hloov tau maj mam txo qis.

DC-DC converter yog ib yam khoom uas tau txais DC input voltage thiab muab DC tso zis voltage.Cov zis hluav taws xob tuaj yeem ua tau ntau dua qhov input voltage thiab vice versa.Cov no yog siv los phim cov load rau lub hwj chim mov.Qhov yooj yim DC-DC converter Circuit Court muaj qhov hloov pauv uas tswj cov khoom thauj mus rau kev sib txuas thiab tshem tawm cov khoom siv hluav taws xob.

Tam sim no, DC converters tau siv dav hauv kev hloov hluav taws xob ntawm lub tsheb hluav taws xob, hluav taws xob tu tsheb, hluav taws xob maus taus thiab lwm yam tsheb hluav taws xob.Lawv kuj tau siv dav hauv xov tooj ntawm tes, MP3, digital koob yees duab, portable media player thiab lwm yam khoom siv.
