Ngenkqubela phambili yetekhnoloji yanamhlanje, ukuvela kwee-inverters kubonelele ngokulula kakhulu kubomi bomntu wonke, ngoko yintoni i-inverter?Isebenza njani inverter?Abahlobo abanomdla kule nto, yiza kwaye ufumane kunye.
Yintoni i-inverter:
I-inverter iguqula amandla e-DC (ibhetri, ibhetri yokugcina) kumandla e-AC (ngokubanzi i-220V, i-50Hz sine wave).Iqukethe ibhulorho ye-inverter, ingqiqo yokulawula kunye nesekethe yokucoca.Isetyenziswa kakhulu kwi-air conditioners, iithiyetha zasekhaya, amavili okusila ombane, izixhobo zombane, oomatshini bokuthunga, iDVD, iVCD, iikhompyutha, iiTV, oomatshini bokuhlamba, iihoods, iifriji, iiVCR, iimassagers, iifeni, izibane, njl. ukuya kwizinga eliphezulu lokungena kweemoto, i-inverter ingasetyenziselwa ukudibanisa ibhetri ukuqhuba izixhobo zombane kunye nezixhobo ezahlukeneyo zokusebenza xa uphuma ukuya emsebenzini okanye ukuhamba.
Inverter umgaqo wokusebenza:
I-inverter yi-DC ukuya kwi-AC transformer, eneneni yinkqubo yokuguqulwa kombane kunye nomguquli.Umguquli uguqula i-AC yombane wegridi yamandla kwi-stable 12V DC output, ngelixa i-inverter iguqula i-12V DC ye-voltage ye-Adapter kwi-high-frequency high-voltage AC;omabini la malungu aphinda asebenzise ubuchule bokumodareyitha kobubanzi bepulse (PWM) esetyenziswa rhoqo.Inxalenye yayo ephambili ngumlawuli odibeneyo we-PWM, i-Adapter isebenzisa i-UC3842, kwaye i-inverter isebenzisa i-chip TL5001.Uluhlu lwamandla okusebenza lwe-TL5001 yi-3.6 ~ 40V.Ixhotywe nge-amplifier yephutha, umlawuli, i-oscillator, i-PWM generator kunye nolawulo lwendawo efileyo, isiphaluka sokukhusela i-voltage ephantsi kunye nesiphaluka esifutshane sokukhusela isiphaluka.
Inxalenye yojongano lwegalelo:Kukho imiqondiso ye-3 kwinxalenye yegalelo, i-12V DC igalelo le-VIN, umsebenzi uvumela i-voltage ENB kunye nePhaneli yolawulo lwangoku lwe-DIM.I-VIN inikezelwa yi-Adapter, i-ENB i-voltage inikezelwa yi-MCU kwi-motherboard, ixabiso layo li-0 okanye i-3V, xa i-ENB = 0, i-inverter ingasebenzi, kwaye xa i-ENB = 3V, i-inverter ikwimeko yokusebenza eqhelekileyo;ngelixa i-DIM yombane Ubonelelwa yibhodi ephambili, uluhlu lwalo lokuhluka luphakathi kwe-0 kunye ne-5V.Amaxabiso ahlukeneyo e-DIM abuyiselwa kwi-terminal yempendulo yomlawuli we-PWM, kwaye okwangoku ebonelelwa yi-inverter kumthwalo nayo iya kwahluka.Ixabiso elincinci le-DIM, lincinci imveliso yangoku ye-inverter.inkulu.
Umjikelo wokuqalisa umbane:Xa i-ENB ikwinqanaba eliphezulu, ikhupha amandla ombane aphezulu ukukhanyisa ityhubhu yesibane somva sePaneli.
Umlawuli we-PWM:Iqukethe le misebenzi ilandelayo: i-voltage yereferensi yangaphakathi, i-amplifier yempazamo, i-oscillator kunye ne-PWM, ukukhuselwa kwe-overvoltage, ukukhuselwa kwe-undervoltage, ukukhusela isiphaluka esifutshane, kunye ne-transistor ephumayo.
Ukuguqulwa kwe-DC:Isiphaluka sokuguqula i-voltage siqulunqwe ityhubhu yokutshintsha i-MOS kunye ne-inductor yokugcina amandla.I-pulse yegalelo ikhuliswa yi-push-pull amplifier kwaye emva koko iqhube ityhubhu ye-MOS ukwenza isenzo sokutshintsha, ukwenzela ukuba i-voltage ye-DC ihlawulise kwaye ikhuphe i-inductor, ukuze esinye isiphelo se-inductor sifumane i-voltage ye-AC.
I-LC oscillation kunye nesekethe yemveliso:qinisekisa umbane we-1600V ofunekayo ukuze isibane siqale, kwaye unciphise umbane ukuya kwi-800V emva kokuba isibane siqalisiwe.
Ingxelo yombane ophumayo:Xa umthwalo usebenza, i-voltage yesampulu ibuyiselwa umva ukuzinzisa ukuphuma kombane we-inverter.
