Inzwa yamanje: Action isimiso futhi ububanzi

Amadivayisi amaningi ukuthi usebenze izifunda kagesi, zidinga izibalo ezinembile ngesikhathi sangempela. Ukunemba lezi izilinganiso kuxhomeke ezintweni eziningi: izinqubo ukulawula izinga ezifundeni control, ukusebenza onokwethenjelwa ukuvikelwa, ukubala lapho kuhlaziywa ukusetshenziswa amandla ukufaka kagesi, njll Ngokuvamile izilinganiso ezifana usebenzisa amadivaysi ekhethekile ayingxenye circuit esikhulu. Ngokwesibonelo, inzwa wamanje is kabanzi umsebenzi kumadivayisi amaningi. Kungaba kwenziwe uma ezihlukahlukene izinto, kuncike ikakhulukazi design wesifunda. It uhlala ingashintshiwe kuphela isimiso ukusebenza kwawo - ngokuhambisana Coefficient kokushumekwe ngaphakathi ke, Ishintsha izitshengiselo ezivela kwamanye transformer ithuluzi noma enye idivayisi ibe isignali voltage okuyinto ifaniswe lonke wesifunda.

Hlukanisa inzwa samanje, yakhelwe ukusebenza ezifundeni AC futhi, ngokufanelekile, zinamandla njalo. Njengoba isibonelo, cabanga ukusebenza ngamunye wabo. Ukuze uthole voltage kushintshana njengoba element wokulinganisa is okuvame ukusetshenziswa kwe-transformer zamanje. Le divayisi yokuxhumana okuyinto uqaphe isimo wesifunda main elawulwa. Isignali kuwo futhi yanikezwa inzwa zamanje, ogama njongo - ukucaca isignali eyamukelwe ukuze circuit control.

Isimo kuyiwa lapho sisebenzelana ipharamitha njalo noma kancane obuhlukahlukene. Transformer ngenhla echazwe isikimu enjalo engathandi ukusebenza, njengoba okhiqizwayo singathola kuphela Dynamics ipharamitha kulinganiswa. Ngokuvamile, amaqhinga anjalo, i-shunt obukhethekile anda isihlobo ukuba lonke ukumelana wesifunda. It is agibele amahhashi ngqo emgqeni. Kulokhu, isuswe voltage iconsi ngalesi ingxenye, okuyinto uzonikezwa futhi Transmitter DC. Kusukela wesifunda yokufakwayo isikimu abanjalo bangabaphostoli at uvundile ke lokhu inzwa imisebenzi eminingana. It galvanically ehlukanisa amandla nezilinganiso izifunda kanyekanye izikali isignali eyamukelwe.

schema ejwayelekile ukuthi usebenza inzwa zamanje siqukethe generator ishayela of imvamisa high, bese kuqaliswa ukhiye ngokwahlukana transformer. Isignali wokulinganisa engenayo is iguqulwe ngu generator isihluthulelo ukuhlukaniswa ngokuvamile ababebuthene FET. Voltage kushintshana ngaleyo ndlela iguqulwe idluliselwa ku i transformer ukuzihlalela. Khona-ke elicwengekileyo futhi Amplified kuncike isilinganiso ukuthi linamathele design.

Isimiso kuyiwa wokusebenza babeka phansi okuthiwa Hall-zamanje inzwa. Kukala ukushuba kazibuthe, okuyinto kuphakama ngenxa ukugeleza samanje umqhubi, futhi oguqula bayifaka isignali okukhipha voltage. Isici yomsebenzi wakhe ukuthi ufundwa emhlabeni wonke futhi ukwazi ukusebenza ngendlela evamile kuzo zonke izifunda. Izinzwa ezinjalo icwecwe futhi babe nezici ezinhle ukusebenza.
