I-Services kagesi ephezulu kakhulu uhlobo lokushintsha imishini esetshenziswa enkampanini yezimboni. Uyini umgomo osebenzayo we-inverters ephezulu? Le mishini ilawulwa yi-Program Logic. I-inferencrencrenct ende ephezulu ingasetshenziswa embonini yezokuxhumana futhi iyithuluzi lokushintsha amakamelo amakhompyutha. Lolu hlobo lokuhlinzekwa kwamandla lungasetshenziswa embonini yamandla elanga kanye nasezimbozweni zamandla okuphehla amandla. Kuyidivaysi yokushintsha kwamandla eshintshayo esebenzisa umphumela wedatha yedatha futhi iphephe kakhulu. Le ndatshana yethula ikakhulukazi umgomo osebenzayo we-inverter ephezulu kakhulu kanye nomehluko phakathi kwe-inverter ephezulu kakhulu kanye ne-inserter ephansi. Landela umhleli ukuze ufunde kabanzi.

I-inferency ende ephezulu iyi-DC to AC Transformer. Empeleni kuyinqubo yokuguqula iVoltage Version ene-Converter. Umgomo osebenzayo we-Inverter Emvamisa ephezulu ukuthi isiguquli siguqula i-ac voltage yegridi yamandla ibe yinto ezinzile ze-DC, Ngenkathi i-inverter iguqula ukuphuma kwe-voltage ye-12V DC nge-adapter ibe imvamisa ephezulu, Amandla aphezulu we-ac; Zombili lezi zingxenye zinokushintshana okusetshenziswa kabanzi kobubanzi be-Pulse (Pwm) Ubuchwepheshe bumukelwa. Ingxenye yayo eyisisekelo iyisilawuli esihlanganisiwe se-PWM, I-adaptha isebenzisa i-UC3842, Futhi i-inverter isebenzisa i-TL5001 chip. Uhla lwe-voltage lwe-voltage lwe-TL5001 lungu-3.6 ~ 40V. Ifakwe ngephutha lephutha, Umlawuli, i-oscillator, I-generator ye-PWM enokulawulwa kwezindawo ezifile, Isifunda esivikelekile se-voltage voltage kanye nomjikelezo wokuvikelwa okufushane.

1. Ingxenye yokuxhuma kokufaka: Ingxenye yokufaka inayo 3 amasiginali, 12V DC OPPT VIN VIN, Ukusebenza Kunika amandla i-Voltage Enb nePaneli Control Signal. I-VIN ihlinzekwa nge-adaptha, kanye ne-Enb Voltage ihlinzekwa yi-MCU ebhodini lomama. Inani layo likhona 0 noma i-3V. Lapho Enb = 0, I-inverter ayisebenzi, Futhi lapho enb = 3V, I-inverter isesimweni esijwayelekile sokusebenza kanye ne-dim valtage inikezwa yi-mainboard, Uhla lwayo lokuhluka luphakathi kuka-0 ~ 5v. Amanani ahlukahlukene afiphali andliwe abuyele kwisilawuli sempendulo yesilawuli se-PWM. Okwamanje kuhlinzekwe yi-inverter emthanjeni nakho kuzohluka. Incane inani elifiphele, okuncane okukhiphayo kwamanje yi-inverter. Omkhulu.

2. I-Voltage Eqala Circuit: Lapho i-ENB isezingeni eliphakeme, Kukhipha i-voltage ephezulu ukukhanyisa i-panel's backight tube.
3. Isilawuli se-PWM: Inemisebenzi elandelayo: I-Internal Reference Voltage, Iphutha Amplifier, oscillator no-pwm, Ukuvikelwa okwengeziwe, Ukuvikelwa kwe-Undervoltage, Ukuvikelwa Komjikelezo Okufushane, kanye nokukhipha ama-transistor.

4. Ukuguqulwa kwe-DC: Umjikelezo wokuguqulwa we-voltage wakhiwa i-tube yokushintsha i-mos kanye ne-inductor yesitoreji samandla. I-PULSE YOKUQHAWUKA IMIPHAKATHI I-Amplifier ye-push-donsa futhi ishayela i-mos tube ukwenza izenzo zokushintsha, ukuze ama-DC voltage ashaje ama-voltage futhi akhiphe i-inductor, ukuze enye ukuphela kwe-inductor ingathola i-ac voltage.

5. I-LC Oscillation kanye ne-Output Circuit: qinisekisa i-1600V Voltage edingekayo ukuqala isibani, futhi wehlise i-voltage kuya ku-800V ngemuva kokuthi isibani sesiqalile.

6. Impendulo yeVoltage Volput: Lapho umthwalo usebenza, I-Sampling voltage isondlisiwe emuva ukuze iqinise umphumela we-inverter Vertage.
