Iyini i-inverter yemoto
I-motor phase modulator YI-circuit esetshenziselwa ukuguqula isignali ukulawula ushintsho lwesigaba senkampani. Isebenza ngokuguqula isignali ngqo ukushintsha amapharamitha e-resonant loop, okwenza isignali yenkampani ishintshe njengoba idlula ku-resonant loop, ngaleyo ndlela yakha igagasi eliguquliwe lesigaba .
Izimo ezithile zohlelo lokusebenza
Ama-modulators esigaba sezimoto asetshenziswa kakhulu emikhakheni yokuxhumana kanye nokucubungula amasignali ukuqinisekisa ukudluliswa okuzinzile kwamasignali kanye nokunemba kokulawulwa kwesigaba. Isibonelo, ekuxhumaneni komsakazo, i-modulator ingasetshenziswa ukuguqula isigaba sesignali yomsakazo ukuqinisekisa ukudluliswa okuzinzile kanye nokulwa nokuphazamiseka .
Izinhlobo zezilungisi zesigaba
Kunezinhlobo ezimbili eziyinhloko zabalawuli besigaba: ukuguqulwa kwesigaba okuqondile kanye nokuguqulwa kwesigaba okungaqondile. Ukuguqulwa kwesigaba okuqondile kufezwa ngokushintsha ngqo amapharamitha wesekethe ye-resonant ngokusebenzisa isignali yokuguqulwa. Ukuguqulwa okungaqondile kuhilela ukuguqula ubukhulu begagasi eliguquliwe kuqala bese kuguqulwa ushintsho lwe-amplitude lube ushintsho lwesigaba ukuze kufezwe ukuguqulwa kwe-.
Umsebenzi oyinhloko we-modulator yesigaba semoto ukusebenzisa isignali eguquliwe ukushintsha ngqo amapharamitha e-resonant loop, ukuze lapho isignali yenkampani idlula ku-resonant loop, kukhiqizwe ukushintsha kwesigaba ukuze kwakheke igagasi le-phase modulation . Ngokukhethekile, i-phase modulator iguqula isignali ngokushintsha amapharamitha esekethe ye-resonant futhi ithonye isigaba sesignali.
Isimiso sokusebenza
I-phase modulator ishintsha amapharamitha wesekethe ye-resonant, okubangela ukuthi isignali yenkampani ishintshe isigaba lapho idlula esekethe ye-resonant futhi yakhe igagasi eliguquliwe lesigaba. Lokhu kushintsha kwesigaba kungafinyelelwa ngokulungisa amapharamitha afana ne-inductance, i-capacitance, njll. ye-resonant loop .
Izimo zohlelo lokusebenza
Ama-Phase modulators asetshenziswa kabanzi emikhakheni efana nokuxhumana, i-radar, kanye nokuzulazula okudinga ukulawulwa kwesigaba. Ngokulawula ngokunembile isigaba sesiginali, i-phase modulator INGALUNGISA futhi ilunciphise ngempumelelo isiginali, iqinisekise ukuzinza nokuthembeka kohlelo lokuxhumana .
Ukwehluleka kokulawula isigaba semoto ye-Youdaoplaceholder0 kubonakala kakhulu njenge-voltage engazinzile, ukusebenza kahle kokushaja okuphansi, ukukhiqizwa kwamandla okungajwayelekile, njll. Izimpawu ezithile zifaka:
I-Youdaoplaceholder0 I-voltage engazinzile : Ukulimala kwezingxenye ezingaphakathi kwe-inverter, njenge-transistors ye-field-effect noma i-transistors yaseDarlington, kungabangela ukwenyuka noma ukwehla kwe-voltage okungavamile, okuthinta isimo sokushaja esivamile sebhethri .
I-Youdaoplaceholder0 Ukusebenza kahle kokushaja okuphansi : Ijeneretha yehluleka ukushaja ibhethri kahle, okwenza amandla ebhethri ehle kancane kancane, noma ivele ime ngokuzumayo ngenkathi ishayela .
I-Youdaoplaceholder0 Ukukhiqizwa kwamandla okungajwayelekile : Ukukhiqizwa kwamandla ngokweqile noma okunganele kuzothinta impilo yebhethri futhi kungabangela ngisho nomonakalo webhethri. Uma ukukhiqizwa kwamandla kuphezulu kakhulu, i-voltage yebhethri ingase yehle ngaphansi kuka-10V, okubangela izinkinga ezifana nokuqala okunzima, ukuthuthumela, ukusheshisa okubuthakathaka .
I-Youdaoplaceholder0 Ubunzima bokuqalisa injini : Injini ingase ingaqali kahle ngenxa ye-voltage engazinzile noma ukushaja okunganele .
I-Youdaoplaceholder0 Ukusetshenziswa kukaphethiloli okwenyukile : Ijeneretha ayisebenzi kahle, okubangela ukuthi injini igcwale ngokweqile, ngaleyo ndlela kwandisa ukusetshenziswa kukaphethiloli .
Izimbangela zokwehluleka kwe-Youdaoplaceholder0 zifaka phakathi:
Umonakalo wengxenye ye-Youdaoplaceholder0 : Ukuphuka noma ukujikeleza okuvulekile kwe-transistor yomphumela wensimu noma i-transistor yaseDarlington ngaphakathi kwe-inverter, okuholela ekuhlulekeni kwe-voltage kanye nokulawula kwamanje .
Inkinga yesekethe ye-Youdaoplaceholder0 : Intambo yokugoqa yokuvuselela yejeneretha iphansi noma ivulekile, okuthinta ukusebenza okuvamile kwesekethe .
Izixazululo ze-Youdaoplaceholder0 zifaka:
I-Youdaoplaceholder0 Hlola bese ushintsha i-inverter : Uma kutholakala i-inverter enephutha, hlola ngokushesha bese ushintsha ingxenye eyonakele noma yonke i-inverter ukuqinisekisa ukusebenza okuvamile kwemoto .
I-Youdaoplaceholder0 Ukulungisa amasekethe : Ngezinkinga zesekethe, kuyadingeka ukuhlola nokulungisa amasekethe avulekile noma izinkinga zomhlabathi .
