Ngokuthuthuka kobuchwepheshe besimanje, ukuvela kwama-inverters kuye kwanikeza ukuphila komuntu wonke, ngakho-ke yini i-inverter?Isebenza kanjani i-inverter?Abangane abanentshisekelo kulokhu, wozani nithole ndawonye.
Yini i-inverter:
I-inverter iguqula amandla e-DC (ibhethri, ibhethri lesitoreji) libe amandla e-AC (ngokuvamile i-220V, 50Hz sine wave).Iqukethe ibhuloho le-inverter, i-logic yokulawula kanye nesifunda sokuhlunga.Isetshenziswa kakhulu kuma-air conditioner, kumathiyetha asekhaya, amasondo okugaya kagesi, amathuluzi kagesi, imishini yokuthunga, i-DVD, i-VCD, amakhompyutha, ama-TV, imishini yokuwasha, ama-hoods, iziqandisi, ama-VCR, ama-massage, izifeni, izibani, njll. ngezinga eliphezulu lokungena kwezimoto, i-inverter ingasetshenziswa ukuxhuma ibhethri ukushayela izinto zikagesi namathuluzi ahlukahlukene ukuze isebenze lapho uphuma ukuya emsebenzini noma uhambo.
Umgomo wokusebenza kwe-inverter:
I-inverter iyisiguquli se-DC kuya ku-AC, empeleni okuyinqubo yokuguqula i-voltage ngesiguquli.Isiguquli siguqula i-voltage ye-AC yegridi yamandla ibe okokuphumayo okuzinzile kwe-12V DC, kuyilapho isiguquli siguqula ukukhishwa kwamandla kagesi angu-12V DC nge-Adapter ibe i-high-frequency high-voltage AC;zombili izingxenye zisebenzisa indlela evame ukusetshenziswa kakhulu yokushintshanisa ububanzi be-pulse (PWM).Ingxenye yayo eyinhloko isilawuli esihlanganisiwe se-PWM, i-Adapter isebenzisa i-UC3842, futhi i-inverter isebenzisa i-chip ye-TL5001.Ububanzi be-voltage esebenzayo ye-TL5001 ngu-3.6 ~ 40V.Ifakwe i-amplifier yephutha, isilawuli, i-oscillator, ijeneretha ye-PWM enokulawula indawo efile, isifunda sokuvikela i-voltage ephansi kanye nesekethe yokuvikela isifunda esifushane.
Ingxenye yesixhumi esibonakalayo sokufaka:Kukhona amasiginali angu-3 engxenyeni yokokufaka, i-12V DC yokufaka i-VIN, i-voltage inikwe amandla i-ENB kanye nesiginali yokulawula yamanje ye-Panel DIM.I-VIN inikezwa i-Adapter, i-ENB voltage inikezwa yi-MCU ebhodini lomama, inani layo lingu-0 noma i-3V, uma i-ENB=0, i-inverter ingasebenzi, futhi uma i-ENB=3V, i-inverter isesimweni esivamile sokusebenza;kuyilapho i-DIM voltage Inikezwe ibhodi elikhulu, ububanzi bayo bokuhluka buphakathi kuka-0 no-5V.Amanani ahlukene e-DIM abuyiselwa kutheminali yempendulo yesilawuli se-PWM, futhi okwamanje okuhlinzekwa yi-inverter kumthwalo nakho kuzohluka.Uma lincane inani le-DIM, liba lincane inani lamanje eliphumayo le-inverter.enkulu.
Isekhethi yokuqalisa i-voltage:Uma i-ENB isezingeni eliphezulu, ikhipha i-voltage ephezulu ukuze ikhanyise ishubhu yesibani sangemuva sephaneli.
Isilawuli se-PWM:Iqukethe imisebenzi elandelayo: i-voltage yereferensi yangaphakathi, i-amplifier yamaphutha, i-oscillator ne-PWM, ukuvikelwa kwe-overvoltage, ukuvikelwa kwe-undervoltage, ukuvikelwa kwesifunda esifushane, kanye ne-transistor ephumayo.
Ukuguqulwa kwe-DC:Isekethe yokuguqula i-voltage yakhiwe i-MOS switching tube kanye ne-inductor yokugcina amandla.I-pulse yokufaka ikhuliswa i-push-pull amplifier bese ishayela ithubhu ye-MOS ukwenza isenzo sokushintsha, ukuze amandla kagesi e-DC ashaje futhi akhiphe i-inductor, ukuze omunye umkhawulo we-inductor ukwazi ukuthola i-AC voltage.
I-LC oscillation kanye nesekhethi yokuphumayo:qinisekisa amandla kagesi angu-1600V adingekayo ukuze isibani siqale, futhi wehlise i-voltage ibe ngu-800V ngemva kokuba isibani siqalisiwe.
Impendulo ye-voltage ephumayo:Lapho umthwalo usebenza, i-voltage yesampula ibuyiselwa emuva ukuze kuzinze ukuphuma kwe-voltage ye-inverter.
