Nekufambira mberi kwehunyanzvi hwemazuva ano, kubuda kwemainverters kwakapa kurerukirwa kwehupenyu hwemunhu wese, saka chii chinonzi inverter?Iyo inverter inoshanda sei?Shamwari dzinofarira izvi, huyai muzive pamwe chete.
Chii chinonzi inverter:
Iyo inverter inoshandura DC simba (bhatiri, bhatiri rekuchengetedza) kuita AC simba (kazhinji 220V, 50Hz sine wave).Iyo ine inverter bhiriji, control logic uye filter circuit.Inoshandiswa zvakanyanya mumhepo inofefetera, dzimba dzemitambo, mavhiri emagetsi ekukuya, maturusi emagetsi, michina yekusonesa, DVD, VCD, makomputa, maTV, washing machines, hoods, mafiriji, VCRs, massager, mafeni, mwenje, etc. Munyika dzekunze, nekuda kusvika pamwero wepamusoro wekupinda kwemotokari, iyo inverter inogona kushandiswa kubatanidza bhatiri kutyaira midziyo yemagetsi uye akasiyana maturusi ekushanda kana uchibuda kuenda kubasa kana kufamba.
Inverter inoshanda nheyo:
Iyo inverter ndeye DC kune AC shanduri, inova chaizvo maitiro emagetsi inversion neinoshandura.Iyo inoshandura inoshandura iyo AC voltage yegridi yemagetsi kuita yakagadzikana 12V DC inobuda, nepo inverter ichishandura iyo 12V DC voltage inobuda neAdapter kuita yakakwirira-frequency yakakwira-voltage AC;ese ari maviri anoshandisawo anowanzo shandiswa pulse wide modulation (PWM) maitiro.Chikamu chayo chepakati iPWM yakasanganiswa controller, iyo Adapter inoshandisa UC3842, uye inverter inoshandisa TL5001 chip.Iyo inoshanda voltage renji yeTL5001 ndeye 3.6 ~ 40V.Iyo inoshongedzerwa ine kukanganisa amplifier, regulator, oscillator, jenareta yePWM ine yakafa zone control, yakaderera voltage yekudzivirira wedunhu uye pfupi dunhu rekudzivirira redunhu.
Input interface chikamu:Pane masaini matatu muchikamu chekuisa, 12V DC yekuisa VIN, basa rinogonesa voltage ENB uye Panel ikozvino yekudzora chiratidzo DIM.VIN inopiwa neAdapter, ENB voltage inopiwa neMCU pabhodhi reamai, kukosha kwayo 0 kana 3V, apo ENB = 0, inverter isingashande, uye kana ENB = 3V, inverter iri mumamiriro ekushanda;nepo DIM voltage Inopihwa nebhodhi hombe, mutsauko wayo uri pakati pe0 ne5V.Yakasiyana DIM tsika dzinodzoserwa kumhinduro terminal yePWM controller, uye yazvino inopihwa neinverter kumutoro ichave yakasiyana.Iyo diki iyo DIM kukosha, idiki iyo inobuda ikozvino yeiyo inverter.chikuru.
Voltage yekutanga siketi:Kana ENB iri padanho repamusoro, inoburitsa yakakwira voltage kuti ibatidze Panel's backlight chubhu.
PWM controller:Iyo ine anotevera mabasa: yemukati referensi voltage, kukanganisa amplifier, oscillator uye PWM, overvoltage kudzivirira, undervoltage dziviriro, pfupi dunhu kuchengetedza, uye inobuda transistor.
DC kutendeuka:Iyo voltage shanduko yedunhu inoumbwa neMOS switching chubhu uye simba rekuchengetedza inductor.Iyo yekupinza pulse inokwidziridzwa ne push-pull amplifier uye yobva yatyaira iyo MOS chubhu kuita switching chiito, kuitira kuti DC voltage ichaja uye inoburitsa inductor, kuitira kuti imwe magumo einductor iwane AC voltage.
LC oscillation uye goho redunhu:simbisa iyo 1600V voltage inodiwa kuti mwenje utange, uye kuderedza voltage kusvika 800V mushure mekunge rambi ratanga.
Mhedziso yekubuda kwemagetsi:Kana mutoro uchishanda, sampling voltage inodzoserwa kuti igadzikane kubuda kwevoltage ye inverter.
