Yini i-inverter?

I-Inverter iyi-DC to AC Transformer, empeleni iyinqubo yokungenelela kweVoltage Inversion ne-Converter. I-Converter iguqula i-ac voltage yegridi yamandla ibe ngumphumela ozinzile we-12v DC, kuyilapho i-inverter iguqula umphumela we-12v DC voltage i-adapter ephezulu-voltage AC; Zombili lezi zingxenye zisebenzisa ubuchwepheshe obusetshenziswa kakhulu be-Pulse Width Modulation (PWM). Ingxenye ebalulekile 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 lunephutha lokukhulisa, umlawuli, i-oscillator, i-PWM generator ephethe umjikelezo we-volm wokuvikela kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ophansi wokuvikela umjikelezo kanye nomjikelezo ovikelekile wesekethe.

Ingxenye ye-Interface Enterface: Ingxenye yokufaka inezimpawu ezi-3, i-12V DC yokufaka i-VIN, ukusebenza kunika amandla i-Voltage Enb kanye nePhaneli Control Signal Dim. I-VIN ihlinzekwe yi-adaptha, futhi i-Enb Voltage ihlinzekwa yi-MCU ebhodini lomama, futhi inani layo lingu-0 noma i-3V. Lapho Enb = 0, i-inverter ayisebenzi, futhi lapho i-Enb = 3V, i-inverter isesimweni esijwayelekile sokusebenza; Futhi i-dim voltage ihlinzekwa yibhodi lomama, futhi uhla lwayo lokuhluka luphakathi kuka-0 no-5V. Amanani ahlukahlukene afiphali andliwe abuyele ekupheleni kwempendulo yesilawuli se-PWM, kanti okwamanje okunikezwe yi-inverter emthanjeni nakho kuzohluka. Inani elincane ivelu efiphele, kukhulu okukhishwayo kwamanje yi-inverter.

I-Voltage Start Loop: Lapho i-ENB iphakeme, i-voltage ephezulu ikhipha ukukhanyisa i-backight tube yephaneli.

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: Umjikelezo wokuguqulwa we-voltage wakhiwa nge-mos switch tube ne-inductor yokugcina amandla. I-PULSE YOKUQHAZA I-PULSE iyandiswa yi-amplifier ye-push-donsa futhi ishayela i-mos tube ukwenza isenzo sokushintsha, ukuze i-DC voltage ishajela futhi 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 siqale.

Impendulo ye-voltage ye-volput: Lapho umthwalo usebenza, i-voltage ye-sampling isondlisiwe emuva ukuze ilinge umkhawulo we-voltage we-i inverter.

Sebenza
I-Inverter iguqula amandla we-DC (ibhethri, ibhethri lesitoreji) libe amandla e-AC (ngokuvamile 220V50hz Sine noma Square Wave). Ngemigomo ye-layman, i-inverter yithuluzi eliguqula liqonde ngqo (i-DC) linye linye (i-AC). Siqukethe ibhuloho le-Inverter, i-Logic Logic kanye ne-Hlunga umjikelezo.
Kalula nje, i-inverter iyithuluzi le-elekthronikhi eliguqula ama-voltage aphansi (ama-volts angu-12 noma ama-24 noma ama-volts angama-48) Amandla we-DC abe ngamandla we-220 ama-volts ac. Ngoba amandla angama-220 ama-ac avame ukulungiswa amandla e-DC ukuze asetshenziswe, futhi indima ye-inverter ihlukile, yingakho igama. Esikhathini se-era of "Mobility", Ihhovisi leselula, ukuxhumana kweselula, ukuzilibazisa kweselula nokuzijabulisa. Uma usohambeni, hhayi kuphela i-voltage eqondile eqondile edingekayo kusuka kumabhethri noma amabhethri wesitoreji, kepha futhi ama-220-volt ashintshashintsha, okubaluleke kakhulu empilweni yansuku zonke. Ama-inverters angahlangabezana nalezi zidingo.
