Ngokuthuthuka kobuchwepheshe besimanje, ukuvela kwama-inverterers kuhlinzeke kalula impilo yawo wonke umuntu, ngakho-ke yini i-inverter? Ngabe i-inserter isebenza kanjani? Abangani abanesithakazelo kulokhu, woza uzothola ndawonye.
Yini i-inverter:
I-Inverter iguqula amandla we-DC (ibhethri, ibhethri lesitoreji) libe amandla e-AC (ngokuvamile 220V, i-50Hz Sine Wave). Iqukethe ibhuloho le-Inverter, i-Logic Logic kanye ne-Hlunga umjikelezo. Isetshenziswa kabanzi endabeni yomoya, ama-homeers asekhaya, amasondo kagesi, amathuluzi kagesi, imishini yokuthunga, i-DVD, ama-vcrs, ama-massager, abalandeli, ukukhanyisa, njll emazweni aphesheya, kufanele Ezingeni lokungena eliphakeme lezimoto, i-inverter ingasetshenziswa ukuxhuma ibhethri ukushayela izinto zikagesi namathuluzi ahlukahlukene okufanele usebenze lapho uzosebenza noma uhambe.
Isimiso sokusebenza kwe-Inverter:
I-Inverter iyi-DC to AC Transformer, empeleni yinqubo yokuphambuka kweVoltage ne-Converter. I-Converter iguqula i-ac voltage yegridi yamandla ibe ngumphumela ozinzile we-12V DC, kuyilapho i-inverter iguqula ukuphuma kwe-adaptha kwe-adapter ephezulu kakhulu Zombili lezi zingxenye zisebenzisa ubuchwepheshe obusetshenziswa njalo be-Pulse Width Modation (PWM). Ingxenye yayo eyisisekelo yisilawuli esihlanganisiwe se-PWM, i-adaptha isebenzisa i-UC3842, futhi i-inverter isebenzisa i-TL5001 chip. Uhla lwe-voltage olusebenzayo lwe-TL5001 lungu-3.6 ~ 40V. Ifakwe ngephutha le-amplifier, umlawuli, i-oscillator, i-generator ye-PWM ephethe indawo efile, umjikelezo ophansi we-voltage uvikelekile kanye nomjikelezo ovikela umjikelezo omfushane.
Ingxenye ye-Interface Enterface:Kunezimpawu ezi-3 engxenyeni yokufaka, i-12V DC yokufaka i-VIN, umsebenzi unika amandla i-Voltage Enb kanye nePhaneli Control Signal Signal. I-VIN ihlinzekwa nge-adaptha, i-Enb Voltage ihlinzekwa yi-MCU kubhodi lomama, inani layo lingu-0 noma i-3v, lapho i-enber = Ngenkathi i-dim voltage enikezwe yibhodi enkulu, uhla lwayo lokuhluka luphakathi kuka-0 no-5V. Amanani ahlukahlukene afiphali andliwe abuyele emuva kwi-Regisebal Terminal yesilawuli se-PWM, kanye namanje enikezwe yi-inverter emthwalweni nawo azohluka. Inani elincane kakhulu, lincane okuphumayo okukhona kwe-inverter. mkhulu.
I-Voltage StartUp Circleit:Lapho i-ENB isezingeni eliphakeme, ikhipha i-voltage ephezulu ukukhanyisa i-baclight tube yephaneli.
Isilawuli se-PWM:Siqukethe imisebenzi elandelayo: I-Internal Reference Verlayifier, i-Oscillator kanye ne-PWM, ukuvikelwa okwedlulele, ukuvikelwa okufushane, ukuvikelwa kwesisu esifushane, nokuvikelwa komjikelezo omfushane, nokuvikelwa okufushane.
Ukuguqulwa kwe-DC:Isifunda sokuguqulwa seVoltage sakhiwa nge-MOS switch tube ne-inductor yokugcina amandla. Ukufakwa kokufaka kukhuliswe yi-amplifier ye-push-donsa bese ushayela i-mos tube ukwenza isenzo sokushintsha, ukuze i-DC voltage ishajela isenzo, ukuze ikhiphe i-inductor, ukuze enye ukuphela kwe-inductor kungathola i-ac voltage.
I-LC Oscillation kanye nokuphuma komjikelezo:Qinisekisa ukuthi i-1600V Voltage edingekayo yesibani ukuqala, futhi inciphise i-voltage ibe ngu-800V ngemuva kokuthi isibani sesiqalile.
Impendulo yeVoltage Volput:Lapho umthwalo usebenza, i-voltage yesampula iyandliwa emuva ukuze iqinise umkhawulo we-inverter.
