Nheyo ye phase modulator.
Modulator yechikamu (phase modulator) idunhu umo chikamu chemutakuri chinodzorwa nechiratidzo chakagadziriswa. Kune nzira mbiri huru dzekugadzirisa sine wave phase: direct phase modulation uye indirect phase modulation. Direct phase modulation ndeyekushandura zvakananga maparamita e resonant loop nekuchinja chiratidzo, kuitira kuti phase shift ibudiswe kana chiratidzo chemutakuri chikapfuura nepakati pe resonant loop uye chikagadzira phase modulation wave. Indirect phase modulation ndeyekutanga kugadzirisa amplitude ye modulated wave, uye wozoshandura amplitude change kuita phase change, kuitira kuti pave ne phase modulation.
Kuzadzikiswa kwakasimba kwekuchinja kwechikamu chakananga uye kusachinja kwechikamu chisina kunanga
Kuchinja kwechikamu chakananga: kushandisa chiratidzo chakagadziriswa kuchinja zvakananga maparamita eresonant loop, kuitira kuti chiratidzo chekutakura chipfuure neresonant loop phase shift. Nzira iyi iri nyore uye yakatwasuka, asi inoda kutonga kwakanyatsojeka kweparamita dzeresonant circuit.
Kuchinja kwechikamu chisina kunanga: amplitude yewave yakagadziriswa inotanga yagadziriswa, uye ipapo kuchinja kweamplitude kunoshandurwa kuita shanduko yechikamu. Nzira iyi yakagadzirwa na Armstrong muna 1933 uye inonzi nzira yekuchinja yeArmstrong.
pulse phase modulator: pulse phase modulator inoshandura output phase yepulse phase modulator kuburikidza neinput pulse output yenumber control device. Kana CNC device yaburitsa forward kana reverse feed pulse, output yepulse phase modulator ichafambisa kana kunonoka chiratidzo chereference nephase Angle inoenderana.
MCU inoita kuti digital phase converter iite: inokonzeresa counter ne clock pulse, kuwedzera kana kubvisa pulse yekuwedzera kuti ichinje output phase yecounter, kuitira kuti pave nephase transformation.
Muenzaniso wekushandiswa kwe phase modulator
Sisitimu yenguva yevharuvhu inoshanduka: Iyo phase modulator ndiyo chinhu chakakosha chesisitimu yenguva yevharuvhu inoshanduka, ichivandudza mashandiro einjini nekudzora chikamu chenguva yevharuvhu.
Mudziyo wekugadzirisa simba remagetsi: Kamera yekugadzirisa mudziyo wekugadzirisa simba remagetsi unoshandiswa kuchengetedza voltage yakaringana musystem yemagetsi.
Kukanganisa kwe automotive phase regulator kunonyanya kuratidzwa sezviratidzo zvekukundikana kwe automotive electronic regulator, zviratidzo izvi zvinosanganisira:
Kuputsika kwemutongi wemagetsi: kuputsika kwetransistor yeFET kana Darlington iri mukati memutongi wemagetsi, zvichiita kuti simba rekufambisa magetsi ripere, zvichiita kuti voltage inobuda mujenareta ikwire, uye bhatiri riwedzere kushaja.
jenareta yakakuvara: Kana jenareta ikakuvara, voltage inobuda inoderera uye bhatiri harigone kuchajwa.
effector kana Darlington tube open-circuit : Kana effector kana Darlington tube open-circuit ikakuvara, jenareta inotenderedza vhiri remagetsi.
Chiratidzo chebhatiri chinobatidzwa kana pasina magetsi anowanikwa: Chiratidzo chebhatiri chinogona kunge chakabatidzwa nekuti hapana magetsi anowanikwa, kana kuti chingave chiri nekuda kwekugadzirwa kwemagetsi akawanda. Kana voltage yebhatiri yaderera pasi pe10 volts, injini inodedera, inonetsa kutanga, kana kuti haigone kumhanya uye kumira.
Zviratidzo izvi zvinoratidza dambudziko nemagetsi emotokari, izvo zvinogona kukanganisa mashandiro emotokari. Saka, kuongororwa nekugadziriswa kwematambudziko aya nenguva kwakakosha zvikuru.
Pamusoro pezvo, zviratidzo zvekukanganisa kwealternator yemotokari zvinosanganisirawo kusachaja, simba rekuchaja diki kwazvo kana kuti rakakura zvakanyanya, uye zvikanganiso izvi zvinogona kunge zvine chekuita nekutadza kwemutongi. Semuenzaniso, kutadza kuchaja kunogona kukonzerwa nebhandi rejenareta rakatyoka, tambo yekutsamwisa jenareta yakatyoka kana tambo yekuchaja, uye kusangana kusina kunaka pakati pebhurashi neringi yekutsvedza. Simba rekuchaja diki kwazvo rinogona kunge riri nekuda kwekubatana kusina kunaka kwetambo yekuchaja, kutsvedza kwebhandi rekutyaira, kutadza kwejenareta kana voltage yemutongi yakaderera zvakanyanya. Simba rekuchaja diki zvakanyanya rinogona kunge riri nekuda kwekuti kukosha kwevoltage yemutongi yemutongi yakakwira zvakanyanya .
Muchidimbu, zviratidzo zvekukundikana kwemota zvinosanganisira bhatiri rakawandisa, bhatiri rakundikana kuchaja, mwenje webhatiri unoratidza mashandiro emota, nezvimwewo, izvo zvinogona kukanganisa mashandiro emota. Saka, zvakakosha kuongorora nekugadzirisa zvikanganiso zvemota nekufamba kwenguva.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemota zveMG&MAUXS zvinogamuchirwa kutenga.
