Mfundo yaikulu ya gawo modulator.
Modulator ya gawo ndi dera lomwe gawo la chonyamulira limayendetsedwa ndi chizindikiro chosinthidwa. Pali njira ziwiri zazikulu zosinthira gawo la sine wave: modulation ya gawo lachindunji ndi modulation ya gawo lachindunji. Modulation ya gawo lachindunji ndikusintha mwachindunji magawo a loop ya resonant posintha chizindikiro, kotero kuti kusintha kwa gawo kumapangidwa pamene chizindikiro cha chonyamulira chimadutsa mu loop ya resonant ndikupanga mafunde a gawo la modulation. Modulation ya gawo lachindunji ndikusintha kaye matalikidwe a mafunde osinthidwa, kenako kusintha kusintha kwa matalikidwe kukhala kusintha kwa gawo, kuti tikwaniritse modulation ya gawo.
Kuzindikira kotheratu kwa kusintha kwa gawo mwachindunji ndi kusintha kwa gawo losalunjika
Kusinthasintha kwa gawo lachindunji: kugwiritsa ntchito chizindikiro chosinthidwa kuti musinthe mwachindunji magawo a resonant loop, kuti chizindikiro chonyamulira chizidutsa mu resonant loop phase shift. Njirayi ndi yosavuta komanso yolunjika, koma imafuna kuwongolera molondola magawo a resonant circuit.
Kusintha kwa gawo losalunjika: kukula kwa mafunde osinthidwa kumasinthidwa kaye, kenako kusintha kwa mafunde kumasinthidwa kukhala kusintha kwa gawo. Njira iyi idapangidwa ndi Armstrong mu 1933 ndipo imatchedwa njira ya Armstrong modulation.
pulse phase modulator: pulse phase modulator imasintha gawo lotulutsa la pulse phase modulator kudzera mu input pulse output ya chipangizo chowongolera manambala. Pamene chipangizo cha CNC chitulutsa pulse ya kutsogolo kapena kumbuyo, kutulutsa kwa pulse phase modulator kudzapititsa patsogolo kapena kuchedwetsa chizindikiro chofotokozera ndi phase Angle yofanana.
MCU imazindikira kusintha kwa gawo la digito: kuyambitsa kugunda kwa wotchi, kuwonjezera kapena kuchotsa kugunda kwina kuti musinthe gawo lotulutsa la counter, kuti mukwaniritse kusintha kwa gawo.
Chitsanzo cha ntchito ya phase modulator
Dongosolo la nthawi ya valve yosinthasintha: Gawo modulator ndiye gawo lofunikira la dongosolo la nthawi ya valve yosinthasintha, lomwe limawongolera magwiridwe antchito a injini powongolera gawo la nthawi ya valve.
Chipangizo chothandizira mphamvu yogwira ntchito: Kamera yosinthira ndi chipangizo chothandizira mphamvu yogwira ntchito chomwe chimagwiritsidwa ntchito kusunga mphamvu yamagetsi mu dongosolo lamagetsi.
Vuto la Automotive Phase Regulator limawonekera makamaka ngati zizindikiro za kulephera kwa Automotive Electronic Regulator, zizindikiro izi zikuphatikizapo:
Kuwonongeka kwa chowongolera magetsi: kuwonongeka kwa transistor ya FET kapena Darlington mkati mwa chowongolera magetsi, zomwe zimapangitsa kuti mphamvu yotulutsa mphamvu isamayende bwino, zomwe zimapangitsa kuti magetsi otulutsa magetsi akwere, komanso kuti batire iwonjezere mphamvu.
Jenereta yawonongeka: Ngati jenereta yawonongeka, mphamvu yotulutsa imachepa ndipo batire silingathe kuchajidwa.
Kuwonongeka kwa effector kapena Darlington chubu chotseguka: Ngati effector kapena Darlington chubu chotseguka chawonongeka, jenereta yoyambitsa kugwedezeka kwa waya imakhazikika.
Chizindikiro cha batri chimayatsidwa pamene palibe magetsi opangidwa : Chizindikiro cha batri chingakhale choyatsidwa chifukwa palibe magetsi opangidwa, kapena chingakhale chifukwa cha kupanga mphamvu zambiri. Pamene magetsi a batri atsika pansi pa 10 volts, injini imagwedezeka, zimakhala zovuta kuyatsa, kapena sizingathe kufulumizitsa ndikuyima.
Zizindikiro izi zimasonyeza vuto la magetsi a galimoto, zomwe zingakhudze magwiridwe antchito a galimotoyo. Chifukwa chake, kuzindikira ndi kukonza zolakwika izi panthawi yake ndikofunikira kwambiri.
Kuphatikiza apo, zizindikiro za vuto la alternator yamagalimoto zimaphatikizaponso kusachaja, mphamvu yochaja ndi yaying'ono kwambiri kapena yayikulu kwambiri, ndipo zolakwika izi zitha kukhala zokhudzana ndi vuto la wowongolera. Mwachitsanzo, kulephera kuchaja kungayambitsidwe ndi lamba wa jenereta wosweka, chingwe choyatsira jenereta chosweka kapena chingwe chochaja, komanso kusagwirizana bwino pakati pa burashi ndi mphete yotsetsereka. Mphamvu yochaja ndi yaying'ono kwambiri ikhoza kukhala chifukwa cha kukhudzana koyipa kwa chingwe chochaja, kutsetsereka kwa lamba woyendetsa, kulephera kwa jenereta kapena mphamvu yolamulira yowongolera ndi yotsika kwambiri. Mphamvu yochaja ndi yayikulu kwambiri ikhoza kukhala chifukwa cha mtengo wa mphamvu yolamulira yowongolera ndi yokwera kwambiri .
Mwachidule, zizindikiro za kulephera kwa modulator ya gawo la galimoto ndi monga kukweza batire, kulephera kwa batire kuyatsa, kuwala kwa chizindikiro cha batire, ndi zina zotero, zomwe zingakhudze magwiridwe antchito abwinobwino a galimoto. Chifukwa chake, ndikofunikira kuzindikira ndikukonza vuto la modulator ya gawo la galimoto pakapita nthawi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
