Umgaqo we-phase modulator.
I-phase modulator yisekethe apho i-phase ye-carrier ilawulwa yisignali ehlengahlengisiweyo. Kukho iindlela ezimbini eziphambili ze-sine wave phase modulation: i-direct phase modulation kunye ne-indirect phase modulation. I-Direct phase modulation kukutshintsha ngokuthe ngqo iiparameter ze- resonant loop ngokuguqula isignali, ukuze i-phase shift iveliswe xa isignali ye-carrier idlula kwi-resonant loop kwaye yenze i-phase modulation wave. I-Indirect phase modulation kuqala kukuguqula i-amplitude ye-modulated wave, uze uguqule utshintsho lwe-amplitude lube lutshintsho lwe-phase, ukuze kufezekiswe i-phase modulation.
Ukuphunyezwa okucacileyo kokuguqulwa kwesigaba ngokuthe ngqo kunye nokuguqulwa kwesigaba esingathanga ngqo
Ukuguqulwa kwesigaba ngokuthe ngqo: ukusebenzisa isignali eguquliweyo ukutshintsha ngokuthe ngqo iiparameters zeluphu ye-resonant, ukuze isignali yomthwali idlule kwi-resonant loop phase shift. Le ndlela ilula kwaye ithe ngqo, kodwa ifuna ulawulo oluchanekileyo lweeparameters zesekethe ye-resonant.
Ukuguqulwa kwesigaba esingangqalanga: i-amplitude ye-modulated wave iyaguqulwa kuqala, ize emva koko utshintsho lwe-amplitude luguqulwe lube lutshintsho lwesigaba. Le ndlela yadalwa ngu-Armstrong ngo-1933 kwaye ibizwa ngokuba yi-Armstrong modulation method.
Imodulator yesigaba sepulse: Imodulator yesigaba sepulse itshintsha isigaba sokuphuma kwemodulator yesigaba sepulse ngokusebenzisa isiphumo sepulse yokufaka yesixhobo solawulo lwenombolo. Xa isixhobo se-CNC sikhupha ipulse yokuphakela phambili okanye engasemva, isiphumo semodulator yesigaba sepulse siya kuqhubekeka okanye sishiye isignali yesalathiso nge-Angle yesigaba esihambelanayo.
I-MCU iyaziqhelanisa ne-digital phase converter: yenza i-trigger counter nge-clock pulse, yongeza okanye ikhuphe i-pulse eyongezelelweyo ukutshintsha i-output phase ye-counter, ukuze kufezekiswe utshintsho lwe-phase.
Umzekelo wesicelo se-phase modulator
Inkqubo yexesha levalvu eguquguqukayo: I-phase modulator yinxalenye ebalulekileyo yenkqubo yexesha levalvu eguquguqukayo, iphucula ukusebenza kwenjini ngokulawula isigaba sexesha levalvu.
Isixhobo sokubuyisela amandla esisebenzayo: Ikhamera yokulungisa sisixhobo sokubuyisela amandla esisebenzayo esisetyenziselwa ukugcina ibhalansi yevolthi kwinkqubo yamandla.
Impazamo yomlawuli wesigaba seemoto ibonakala kakhulu njengeempawu zokusilela komlawuli we-elektroniki weemoto, ezi mpawu ziquka:
Ukwaphuka komlawuli wevolthi : ukwaphuka kwetransistor yeFET okanye iDarlington ngaphakathi komlawuli wevolthi, okubangela ukuba umsinga wokukhupha uphelelwe ngamandla, okubangela ukuba ivolthi yokukhupha yejenereyitha inyuke, kwaye ibhetri itshaje kakhulu.
ijenereyitha yonakele: Ukuba ijenereyitha yonakele, i-voltage yokukhupha iyancipha kwaye ibhetri ayinakutshajwa.
Umonakalo we-effector okanye ityhubhu yaseDarlington: Ukuba umonakalo we-effector okanye ityhubhu yaseDarlington yonakaliswe yi-open-circuit, i-generator excitation winding lead iyancitshiswa.
Isalathisi sebhetri sivuliwe xa kungekho mbane uvelayo: Isalathisi sebhetri sisenokuba sivuliwe kuba akukho mbane uvelayo, okanye sisenokuba sibangelwa kukuveliswa kwamandla aphezulu. Xa i-voltage yebhetri yehla ngaphantsi kwe-10 volts, injini iyaxengaxenga, kunzima ukuyiqala, okanye ayikwazi ukukhawulezisa kwaye ima.
Ezi mpawu zibonisa ingxaki kwinkqubo yombane yemoto, enokuthi ichaphazele kakubi ukusebenza kwemoto. Ke ngoko, ukuxilongwa nokulungiswa kwezi ngxaki ngexesha elifanelekileyo kubaluleke kakhulu.
Ukongeza, iimpawu zempazamo ze-alternator yemoto ziquka ukungatshaji, umsinga wokutshaja umncinci kakhulu okanye mkhulu kakhulu, kwaye ezi mpazamo zinokunxulunyaniswa nempazamo yomlawuli. Umzekelo, ukungaphumeleli kokutshaja kunokubangelwa yibhanti yejenereyitha ephukileyo, umgca wokuchukumisa wejenereyitha ophukileyo okanye umgca wokutshaja, kunye nonxibelelwano olubi phakathi kwebhrashi kunye neringi yokutyibilika. Umsinga wokutshaja umncinci kakhulu unokubangelwa kunxibelelwano olubi lomgca wokutshaja, ukutyibilika kwebhanti yokuqhuba, ukusilela kwejenereyitha okanye i-voltage yokulawula iphantsi kakhulu. Umsinga wokutshaja umkhulu kakhulu unokubangelwa kukuba ixabiso le-voltage yokulawula i-regulator liphezulu kakhulu .
Ngamafutshane, iimpawu zokungaphumeleli kwe-modulator yesigaba semoto ziquka ukutshaja kakhulu kwebhetri, ukungaphumeleli kwebhetri ukutshaja, isibane sesalathisi sebhetri, njl.njl., nto leyo enokuchaphazela ukusebenza kwemoto okuqhelekileyo. Ke ngoko, kuyimfuneko ukufumanisa nokulungisa impazamo ye-modulator yesigaba semoto ngexesha.
