Izixhobo zombane ze-inverter ze-high-frequency luhlobo lwezixhobo zokutshintsha ezisetyenziswa kwindawo yoshishino. Uthini umgaqo wokusebenza kwee-inverters eziphezulu ze-frequency? Esi sixhobo silawulwa ngengqiqo yeprogram. I-inverter ephezulu inokusetyenziswa kwishishini lezonxibelelwano kwaye sisixhobo sokutshintsha kumagumbi ekhompyuter. Olu hlobo lonikezelo lwamandla lunokusetyenziswa kwishishini lamandla elanga kunye neshishini lokuvelisa amandla. Sisixhobo sombane esitshintshayo esisebenzisa imveliso yomgca wedatha kwaye sikhuseleke kakhulu. Eli nqaku ikakhulu lazisa umgaqo osebenzayo we-inverter ephezulu-frequency kunye nomahluko phakathi kwe-high-frequency inverter kunye ne-low-frequency inverter.. Landela umhleli ukuze ufunde ngakumbi.

I-inverter ephezulu-frequency yi-DC ukuya kwi-AC transformer. Ngokwenene yinkqubo yokuguqula i-voltage ene-converter. Umgaqo osebenzayo we-high-frequency inverter kukuba umguquli uguqula amandla ombane we-AC wegridi yamandla kwimveliso ezinzileyo ye-12V DC., ngelixa i-inverter iguqula i-12V DC ye-voltage output yi-Adapter ibe yi-high-frequency, amandla ombane aphezulu e-AC; omabini la malungu alinganayo Uguqulo olusetyenziswa ngokubanzi lwepulse ububanzi (PWM) iteknoloji yamkelwe. Inxalenye yayo ephambili ngumlawuli odibeneyo we-PWM, i-Adapter isebenzisa i-UC3842, kwaye i-inverter isebenzisa i-TL5001 chip. Uluhlu lwe-voltage yokusebenza ye-TL5001 yi-3.6 ~ 40V. Ixhotyiswe ngeamplifier yempazamo, umlawuli, i-oscillator, ijeneretha ye-PWM enolawulo lwezowuni efileyo, i-low-voltage protection circuit kunye ne-short-circuit protection circuit.

1. Igalelo loqhagamshelo inxalenye: Ingxenye yegalelo ine 3 iimpawu, 12V DC igalelo VIN, ukusebenza kwenza amandla ombane ENB kunye nePaneli yolawulo lwangoku uphawu DIM. I-VIN inikezelwa yi-Adapter, kunye ne-ENB yombane ibonelelwa yi-MCU kwi-motherboard. Ixabiso layo li 0 okanye 3V. Xa ENB=0, i-inverter ayisebenzi, kwaye xa ENB=3V, i-inverter ikwimeko yokusebenza eqhelekileyo kwaye i-DIM yombane ibonelelwa yi-mainboard, uluhlu lwalo lokwahluka luphakathi kwe-0 ~ 5V. Amaxabiso ahlukeneyo e-DIM anikwa umva kwi-terminal yempendulo yomlawuli we-PWM. Ikhoyo ngoku enikezelwa yi-inverter kumthwalo nayo iya kuhluka. Lincinci ixabiso le-DIM, incinci imveliso yangoku nge-inverter. Enkulu.

2. I-Voltage start circuit: Xa i-ENB ikwinqanaba eliphezulu, ikhupha amandla ombane aphezulu ukukhanyisa ityhubhu yokukhanya ngasemva kwePaneli.
3. Umlawuli we-PWM: Inemisebenzi elandelayo: Umbane wesalathiso sangaphakathi, iamplifier yemposiso, oscillator kunye ne-PWM, ukhuseleko overvoltage, ukhuseleko undervoltage, ukhuseleko lwesiphaluka esifutshane, kunye nemveliso ye-transistor.

4. Ukuguqulwa kweDC: Isekethe yokuguqula i-voltage yenziwe ityhubhu yokutshintsha i-MOS kunye ne-inductor yokugcina amandla. I-pulse yegalelo ikhuliswa yi-push-pull amplifier kwaye iqhube ityhubhu ye-MOS ukwenza iintshukumo zokutshintsha., ukuze amandla ombane eDC ahlawule kwaye akhuphe i-inductor, ukuze esinye isiphelo se-inductor sifumane i-AC voltage.

5. I-LC oscillation kunye nesekethe yemveliso: qinisekisa ukuba amandla ombane ayi-1600V afunekayo ukuqalisa isibane, kwaye unciphise amandla ombane ukuya kwi-800V emva kokuba isibane siqalisiwe.

6. Ingxelo yombane ophumayo: Xa umthwalo usebenza, umbane wesampulu ubuyiselwa umva ukuzinzisa imveliso yombane we-inverter.
