Yini 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.
Kalula nje, i-Inverter iyithuluzi le-elekthronikhi eliguqula ama-voltage aphansi (ama-volts ayi-12 noma angama-24 noma ama-48 volts) aqonde njengamanje kuma-220 volts angena kumanje. Ngoba sivame ukusebenzisa i-220-volt eshintshashintsha inqubo yamanje yokuyiguqula ibe yamanje, futhi i-inverter isebenza ngaphesheya, yingakho igama.
Yini aI-Sine Wave Inverter
Ama-inverter angahlukaniswa ngokuya ngemibukiso yawo yokuphuma, a. Ihlukaniswe yaba yi-Square Wave Inverters, b. ama-inverters aguquliwe aguquliwe kanye c. ama-inverters we-sine wave.
Ngakho-ke, incazelo ye-sine wave inverter iyinhlanganon enserter yawo ama-wavelform we-sine.
Inzuzo yayo ukuthi i-wavexform ye-wavexform ilungile, ukuhlanekezela kuphansi kakhulu, futhi i-waveform yayo yokuphuma ihambisana ngokulingana ne-ac waveform yegridi yamamain. Eqinisweni, ikhwalithi yamandla e-AC enikezwe yimihle kakhuluI-Sine Wave Inverteriphakeme kunaleyo yegridi. I-Sine Wave Inverter inokuphazanyiswa okuncane emsakazweni, imishini yokuxhumana kanye nemishini yokunemba, umsindo ophansi, ukungazimiswanga okuqinile, kungahlangabezana nokusetshenziswa kwayo yonke imithwalo ye-AC, futhi wonke umshini unamandla aphezulu; Okubi kwayo ukuthi umugqa kanye nokulungiswa kokulungiswa kwe-wave inverter in-inverter kuyinkimbinkimbi, inezidingo eziphakeme zokulawula ama-chip kanye nobuchwepheshe bokulungisa, futhi kuyabiza.
Isebenza kanjani?
Ngaphambi kokwethula umgomo wokusebenza weI-Sine Wave Inverter, qala ukwethula umgomo wokusebenza we-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, futhi luhlome ngephutha lokukhulisa, umlawuli, i-oscillator, i-PWM generator ephethe indawo efile, umjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ovikelekile wesekethe.
Ingxenye ye-Interface Enterface: Kunezimpawu ezi-3 engxenyeni yokufaka, i-12V DC yokufaka i-VIN, umsebenzi unika amandla i-Voltage Enb nePaneli Control Signal Dim. 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 Circuit: Lapho i-ENB isezingeni eliphakeme, ikhipha i-voltage ephezulu ukukhanyisa i-PANELL TUBHOBE TUBE.
Isilawuli se-PWM: Siqukethe le misebenzi elandelayo: I-Internal Reference Verlayifier, i-Oscillator kanye ne-PWM, ukuvikelwa okuphezulu, ukuvikelwa okufushane, ukuvikelwa komjikelezo omfushane, nokuvikelwa okufushane komjikelezo, nokuvikelwa okufushane, nokuvikelwa okufushane.
Ukuguqulwa kwe-DC: Isifunda sokuguqulwa seVoltage sakhiwa nge-Mons Shintsha Tube ne-Inductor Yezindawo Zokugcina. 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 i-1600V Voltage edingekayo yesibani ukuqala, futhi inciphise i-voltage ibe ngu-800V ngemuva kokuthi isibani sesiqalile.
Impendulo ye-voltage ye-volput: Lapho umthwalo usebenza, i-voltage ye-sampling isondlisiwe emuva ukuze ilinge umkhawulo we-voltage we-i inverter.
(Complex Sine Wave Circuit DIAGRAM)
Umehluko phakathi kwe-inverter ye-Sine Wave kanye ne-inverter ejwayelekile ukuthi i-wavexform yayo yokuphuma iyigagasi eliphelele elinegagasi elinezinga lokuhlanekezela kanye, ngakho-ke akukho okuphansi kakhulu, umsebenzi wokuvikela uqedile , futhi ukusebenza kahle ngokuphelele.
Isizathu esenzaI-Sine Wave InverterKungakhipha i-wave ephelele ye-sine yingoba isebenzisa ubuchwepheshe be-SPWM obuthuthuke kakhulu kunobuchwepheshe be-PWM.
Umgomo we-SPWM ususelwa kwisimiso esifanayo esithi i-pulses act kumadivayisi womsebenzi wesikhathi: Uma ama-pulses esebenza kumadivayisi womsebenzi wesikhathi, umkhiqizo wenani eliphakeme lesikhathi, lesikhathi sesenzo siyalingana, futhi le pulses ingalinganiswa ukuze ilingane.
I-SPWM iqhathanisa igagasi elingunxantathu linemvamisa elimisiwe nenani eliphakeme eliphakeme (njengokushintsha okuvame ukushintshanisa i-10k Isethenjwa uSine Wave edivayisini. I-amplitude ne-frequency of the reference sine wave aguqulwe ukukhiqiza ukuguquguquka kwe-DC Volse Pullse Wordation Movieth okulingana nesethenjwa segagasi elinama-amplitude ahlukile namaza.
