Mfundo 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: kusinthika kwa gawo molunjika komanso kusinthika kwa gawo losalunjika. Kusintha kwachindunji kwa gawo ndikusinthira mwachindunji magawo a resonant loop posintha siginecha, kotero kuti kusintha kwa gawo kumapangidwa pamene chizindikiro chonyamulira chikudutsa pamtundu wa resonant ndi mawonekedwe osinthira gawo. yosalunjika gawo kusinthasintha ndi choyamba modulate matalikidwe a yoweyula modulated, ndiyeno kusintha matalikidwe kusintha mu gawo kusintha, kuti tikwaniritse gawo kusinthasintha. pa
Kuzindikira konkire kwa kusinthasintha kwachindunji ndi kusinthika kwagawo kosalunjika
Direct gawo kusinthasintha: ntchito modulated chizindikiro kusintha mwachindunji magawo a kuzungulira resonant, kuti chonyamulira chizindikiro kudzera resonant kuzungulira gawo kusintha. Njirayi ndi yophweka komanso yolunjika, koma imafuna kulamulira bwino kwa magawo a dera la resonant.
Kusinthasintha kwachindunji: matalikidwe a mafunde osinthika amasinthidwa poyamba, ndiyeno kusintha kwa matalikidwe kumasinthidwa kukhala kusintha kwa gawo. Njirayi 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 pakulowetsa kutulutsa kwa chipangizo chowongolera manambala. Chipangizo cha CNC chikatulutsa kugunda kwapatsogolo kapena kubweza, kutulutsa kwa pulse phase modulator kumatsogola kapena kulepheretsa chizindikirocho ndi ngodya yofananira. pa
MCU imazindikira chosinthira cha digito: yambitsani kugunda kwa wotchi, onjezani kapena chotsani kugunda kwina kuti musinthe gawo lotulutsa, kuti muzindikire kusintha kwa gawo. pa
Chitsanzo chogwiritsira ntchito gawo la modulator
Njira yosinthira ma valve: Modulator ya gawo ndiye gawo lofunikira pakusintha nthawi ya valve, kukhathamiritsa magwiridwe antchito a injini powongolera gawo la nthawi ya valve. pa
Chipangizo cholipirira mphamvu zamagetsi: Kamera yosinthira ndi chipangizo cholipirira mphamvu chomwe chimagwiritsidwa ntchito kuti magetsi azikhala bwino mumagetsi. pa
Kuwonongeka kwa zowongolera zamagalimoto kumawonetsedwa makamaka ngati zizindikiro za kulephera kwamagetsi owongolera magalimoto, zizindikiro izi ndi monga:
Kuwonongeka kwa ma voltage regulator : Kuwonongeka kwa FET kapena Darlington transistor mkati mwa voteji regulator, kuchititsa chisangalalo chapano kutha mphamvu, zomwe zimapangitsa kuti mphamvu ya jenereta iwuke, ndipo batire ichuluke.
Jenereta yawonongeka : Ngati jenereta yawonongeka, mphamvu yotulutsa imachepa ndipo batire silingathe kuimbidwa.
effector kapena Darlington chubu lotseguka-dera kuwonongeka : Ngati effector kapena Darlington chubu lotseguka dera kuwonongeka, jenereta excitation mapiringidzo kutsogolo kwapansi.
Chizindikiro cha batri chimayatsidwa pamene palibe magetsi opangidwa : Chizindikiro cha batri chikhoza kukhala choyaka chifukwa palibe magetsi omwe amapangidwa, kapena mwina chifukwa cha mphamvu zambiri. Mphamvu ya batri ikatsika pansi pa 10 volts, injini imagwedezeka, zimakhala zovuta kuyambitsa, kapena sizingafulumire ndi kuyima.
Zizindikirozi zimasonyeza vuto la magetsi a galimoto, zomwe zingasokoneze ntchito ya galimoto. Chifukwa chake, kuzindikira munthawi yake ndikukonzanso zolephera izi ndizofunikira kwambiri.
Kuphatikiza apo, zolakwika za alternator yamagalimoto zimaphatikizansopo kusalipira, kuyitanitsa komwe kuli kochepa kapena kwakukulu kwambiri, ndipo zolakwika izi zitha kukhala zokhudzana ndi vuto la wowongolera. Mwachitsanzo, kulephera kulipiritsa kungayambitsidwe ndi lamba wosweka wa jenereta, chingwe chokokera cha jenereta chosweka kapena chingwe cholipiritsa, komanso kusalumikizana bwino pakati pa burashi ndi mphete yolumikizira. Kulipiritsa ndikocheperako kungakhale chifukwa cha kusalumikizana bwino kwa chingwe chothamangitsira, kutsetsereka kwa lamba woyendetsa, kulephera kwa jenereta kapena mphamvu yamagetsi yowongolera ndiyotsika kwambiri. Mphamvu yolipiritsa ndi yayikulu kwambiri mwina chifukwa voteji ya regulator ndiyokwera kwambiri.
Mwachidule, zizindikiro za kulephera kwa modulator ya galimoto kumaphatikizapo kuwonjezereka kwa batri, kulephera kwa batri, kuwala kwa batri, ndi zina zotero, zomwe zingakhudze momwe galimoto ikuyendera. Chifukwa chake, ndikofunikira kuzindikira ndikukonza zolakwika zamagawo agalimoto munthawi yake.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
