Cov teeb meem tshwm sim thaum siv hloov hluav taws xob
Dab tsi yuav tsum tau sau tseg thaum xaiv lub pob hluav taws xob hloov?
Teb: Txhawm rau nce lub neej ntawm lub tshuab hloov hluav taws xob, nws raug pom zoo kom xaiv cov qauv nrog 30% ntau cov khoom siv hluav taws xob tsawg dua. Piv txwv li, yog tias lub system yuav tsum muaj 100W fais fab mov, nws raug nquahu kom xaiv lub zog hluav taws xob ntau dua 130W, thiab lwm yam tuaj yeem txhim kho lub neej ntawm lub zog ntawm lub zog. Ib qho ntxiv, nws yog ib qho tsim nyog los xav txog qhov chaw ua haujlwm ua haujlwm ntawm lub zog hluav taws xob thiab seb puas muaj cov khoom siv cua sov ntxiv. Qhov ntsuas cov zis tawm ntawm lub zog hluav taws xob yuav raug txo kom muaj cov cua sov siab. Xaiv ntau yam haujlwm raws li cov ntawv thov: Kev Tiv Thaiv Kev Tiv Thaiv: Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv (OTP) Xaiv cov kev nyab xeeb kev nyab xeeb thiab hluav taws xob sib xyaw (EMC).
2. Kuv puas tuaj yeem nug yog tias lub zog siv tau rau 45 ~ 440Hz? Yog tias muaj, puas muaj lwm yam cuam tshuam?
Teb: Hloov cov khoom siv hluav taws xob feem ntau tuaj yeem siv rau hauv qhov ntau zaus. Txawm li cas los xij, yog tias zaus siv tau tsawg dhau, nws yuav ua rau muaj kev txo qis hauv kev ua tau zoo. Piv txwv, thaum cov lus qhia voltage yog 23 {7} par thiab cov kev ntsuas ntawm lub tswv yim ntawm lub hwj chim yog 6 {} hz. Txawm li cas los xij, yog tias zaus ntawm cov tswv yim AC lub zog yog txo kom tsawg rau 5 {13 hz, kev ua tau zoo yog 83.8%; Thaum nws tseem siab dhau, nws yuav ua rau txo qis hauv PF tus nqi ntawm cov qauv nrog PFC muaj nuj nqi, thiab tseem nce cov xau dej tam sim no. Piv txwv li, thaum lub tswv yim AC qhov zaus yog 60Hz, lub zog muaj zog yog 0.93, thiab cov xau dej tam sim no yog 0.7vac thiab rated load; Thaum cov zaus ntawm cov tswv yim AC lub zog yog 440Hz, lub hwj chim tsim txo mus rau 0.75, thaum lub toast nce mus rau 4.3ma.
3. Yog tias ib qho hluav taws xob ntawm 24V yog qhov yuav tsum tau thiab Gaoxin tsis muaj cov qauv no, tuaj yeem ob lub 12v units txuas nrog hauv series?
Teb: Yog, tab sis nws yog ib qho tseem ceeb kom nco ntsoov tias qhov tsawg kawg ntawm cov qauv uas tau txais kev sib txuas tau los ntawm cov txheej txheem tom qab kev sib txuas lus tom qab cov txheej txheem. Ib qho ntxiv, txhawm rau tiv thaiv qhov tau ntawm sab hauv capacitor kev puas tsuaj los ntawm cov fais fab kev sib txuas, nws raug pom zoo kom txuas nrog Diode rau SPU OUT DESUES OUT DESUCE DESUSION.
Yog tias xav tau 600W hluav taws xob yuav tsum tau, tuaj yeem ob lub thib 300W cov chav nyob txuas nrog hauv parallel?
Teb: Nws tsis tuaj yeem txuas ncaj qha rau hauv parallel. Vim yog cov qauv tsim dav dav ntawm 300W yam tsis muaj kev ua haujlwm sib txawv, thaum ob cov khoom siv fais fab muaj cov tshuaj tawm txawv hluav taws xob, cov hluav taws xob ntau dua los yog tag nrho cov poob. Nws raug nquahu kom siv tus qauv nrog kev ua haujlwm sib dhos.
Ntsuas ob lub teeb ntawm cov zis hluav taws xob cov khoom siv, {{0} v yog lawm, tab sis {{v tshaj qhov tshwj xeeb. Dab tsi yog vim li cas?
Teb: Ntau txheej (2 lossis ntau dua) ntawm cov qauv tso zis hauv cov khoom lag luam qib siab muaj cov khoom yuav tsum tau ua. Thov saib phau ntawv ua ntej siv. Thaum 5V / 4A thiab 12V / 1A tau siv, 12V / utput Voltage yog dhau siab dhau, kwv yees li ntawm ± 6% (12.72V) hais hauv phau ntawv. Yog tias ib qho tsawg kawg nkaus load ntawm 0. 2A yog ntxiv rau 12v raws li phau ntawv, lub 12V tso zis voltage tuaj yeem raug txo kom txog 12.3v.
