Lapho uhlobisa futhi uklama izintambo, udinga futhi ukunaka ekukhethweni kokushintshwa kwamandla okuyinhloko.Phela, kukhona ukushintsha kwamandla amakhulu amaningi, futhi afaniswa nobubanzi be-voltage ehlukene namandla okukhiphayo.izici zokulayisha, njll. Okulandelayo indlela yokukhetha imodi yokusebenza yokushintsha ukunikezwa kwamandla nokushintsha ukunikezwa kwamandla.Enqubweni yokukhetha ukunikezwa kwamandla okushintshayo, singanaka lezo zinkinga, bese sizame ukukhetha okumenyezelwe ukushintshwa kwemikhiqizo yokuphakelwa kwamandla, futhi umphumela wesicelo uzoba ngcono kakhulu.
Indlela yokukhetha ukunikezwa kwamandla okushintshayo.
Lapho ukhetha ukunikezwa kwamandla okushintshayo, ububanzi be-voltage yokufaka, amandla okukhiphayo amaphakathi, izici zomthwalo, nezinga lokushisa lokusebenza kufanele kucatshangelwe.
1. Khetha ububanzi obufanele bokufaka amandla kagesi.Thatha ukuthayipha kokuxhumana njengesibonelo.Ukucaciswa kwamandla kagesi okokufaka okujwayelekile kungu-110V kanye no-220V, ngakho-ke kukhona ukuguqulwa kwe-110V.220V AC kanye ne-voltage yokufaka evamile (AC: 85V-2**V).Imodeli yokucaciswa kwe-voltage yokufaka kufanele ikhethwe ngokuya ngendawo yohlelo lokusebenza.
2. Khetha amandla okukhiphayo afanelekile.Ukunikezwa kwamandla okushintshayo kusebenzisa ingxenye yamandla okukhiphayo phakathi nokusebenza futhi kuyawakhulula njengamandla okushisa.Ukuze kwandiswe kangcono impilo yesevisi yokushintsha kwamandla kagesi, kuhlongozwa ukuba kukhethwe imishini enamandla alinganiselwe angaphezu kwama-30%.
3. Cabangela izici zomthwalo.Ukuze kuthuthukiswe kangcono ukuzinza kwesistimu yokusebenza, kuhlongozwa ukuthi kushintshwe ukunikezwa kwamandla okusebenza ngaphansi komthwalo we-50% -80%, okungukuthi, kucatshangwa ukuthi amandla okukhiphayo avamile angama-20W, ukunikezwa kwamandla okushintshwa amandla we-25W-40W kufanele akhethwe.
Uma umthwalo kuyinjini, i-bulb light noma i-capacitor load, yamanje inkulu uma iqala, futhi ukunikezwa kwamandla okushintshayo okufanelekile kufanele kukhethwe ukuvimbela umthwalo.Uma umthwalo kuyinjini, ukuguqulwa kwe-voltage ekuvaleni kufanele kucatshangelwe.
4. Ukwengeza, izinga lokushisa elisebenzayo lokuphakelwa kukagesi okushintshayo kanye nokuthi kukhona yini okokusebenza okweqile okupholisa okuyisizayo nakho kufanele kucatshangelwe.Ukunikezwa kwamandla okuzwa izinga lokushisa okuphezulu kakhulu kufanele kunciphise okukhiphayo.Sicela ubheke ijika lokwehliswa kwamandla okuzwa izinga lokushisa.
Ithini imodi yokusebenza ye-switching power supply?
Imvamisa.Imodi emisiwe yobubanzi be-Pulse, imvamisa ilungisiwe.Imodi eguquguqukayo yobubanzi be-Pulse, imvamisa.Imodi eguquguqukayo yobubanzi be-Pulse.
1. Imodi yokusebenza yangaphambili isetshenziswa kakhulu ekunikezeni amandla okuguquguquka kwe-DC/AC noma ukuguqulwa kwamandla kagesi e-DC/DC;izindlela ezimbili zokugcina zokusebenza zisetshenziswa kakhulu ekushintsheni ukunikezwa kwamandla okulawulwayo.
2. Ngaphezu kwalokho, i-voltage ephumayo ye-switching power supply nayo inezinhlobo ezintathu zokusebenza: indlela ye-voltage ephuma ngokushesha, indlela ye-avareji ephumayo kagesi, kanye nendlela ye-amplitude value output voltage.
3. Ngendlela efanayo, indlela yokusebenza yangaphambili isetshenziswa kakhulu ekunikezeni amandla okuguquguquka kwe-DC/AC noma ukuguqulwa kwamandla kagesi e-DC/DC;izindlela ezimbili zokugcina zokusebenza zisetshenziswa kakhulu ekushintsheni ukunikezwa kwamandla okulawulwayo.
Ngokwemodi yesixhumi esibonakalayo yekhabethe lokushintsha kumjikelezo wokulawula, amandla okushintsha ngokuvamile angahlukaniswa abe yizinhlobo ezintathu: uchungechunge lokushintsha kwamandla kagesi, ukunikezwa kwamandla okushintshaniswa okuhambisanayo, kanye nokunikezwa kwamandla okushintsha i-transformer.Phakathi kwazo, i-transformer switching power supply (ngemuva kwalokhu ebizwa ngokuthi i-transformer switching power supply) ingabuye ihlukaniswe ibe: uhlobo lomnyango oslayidayo, ingalo eyisicaba, uhlobo olugcwele lwebhuloho, njll.;ngokusho kokukhuthazwa kwe-transformer yamandla kanye nomehluko wesigaba se-voltage okukhiphayo, ingahlukaniswa ibe: ukuvusa phambili, ukuhlehla kwe-Excited, okukodwa-okujabulisayo, okuphindwe kabili;uma inhloso eyinhloko ihlukaniswe ngenani elikhulu lezinhlobo.
Imininingwane engenhla yindlela yokukhetha imodi yokusebenza yokushintsha ukunikezwa kwamandla nokushintsha ukunikezwa kwamandla.Lapho ukhetha inkinobho enkulu yamandla, udinga ukubona ngokucacile izinga le-voltage namandla okukhiphayo anengqondo.Uma i-voltage iphakeme ngokuqhathaniswa, kufanele futhi uphathe umthamo womthwalo wale nto.Ngaphezu kwalokho, empeleni, ukushintsha kwamandla kunezinhlobo ezihlukahlukene zezindlela zokusebenza, kufaka phakathi imvamisa engaguquki, ububanzi be-pulse, njll., ngakho-ke kufanele kukhethwe ngokuvumelana nobubanzi bohlelo lokusebenza ekhaya.
