Chii chinonzi inverter?

Iyo inverter is a dc ku AC transformer, iyo iri chaiyo yekuvhiringidzika inversion maitiro neanoshandura. Iyo inoshandura inoshandura AC voltage yeSimba Giredhi mune yakagadziriswa 12V inobuda Zvikamu zviviri zviviri zvinoshandisawo izvo zvinowanzoshandiswa zvinoshandiswa prse uplit modulation (PWM) tekinoroji. Iyo core chikamu chikamu chakabatanidzwa pWM Iyo yekushandisa voltage renji yeTL5001 iri 3.6 ~ 40v, uye ine mboblifier, mugadziri weSoulator neDunhu rakafa, Dunhu rakadzika-dziviriro uye pfupi redunhu dziviriro.

Input Interface chikamu: Iyo yekuisa chikamu ine masaini matatu, 12V DC yekupinda vin, kushanda inogonesa vhorosi enb uye pane yePante Cont control chiratidzo. Vin inopihwa neAdapta, uye enb voltage inopihwa neiyo mcu pane amaibhodhi, uye kukosha kwayo ndeye 0 kana 3V. Kana Enb = 0, iyo Inverter haina kushanda, uye kana Enb = 3V, iyo inverter iri mune yakajairika mamiriro; Uye iyo Dim Voltage inopihwa naAmaiboard, uye kusiyana kwayo kusiyana kuri pakati pe 0 na5v. Tsika dzakasiyana DIM dzinodyiswa dzinosvika kumhinduro yekupera kwePWM Controller, uye zvazvino zvinopihwa neyechivharo kumutoro zvichasiyana. Iyo diki iyo dim kukosha, iyo yakakura iyo inobuda iripo neiyo Inverter.

Voltage Start Loop: Kana Enb yakakwira, yakakwira voltage ndeyekubuda pachena kuti uvhenekere backlight tube.

PWM Controller: Inosanganisira mabasa anotevera: Yemukati Reference voltage, Escultifier, Oscillator nePWM, Dziviriro Yakadzika, Pfupi dziviriro dzedunhu, uye transistor.

Dunhu reDNC Iyo Input Pulse inokwidziridzwa neiyo pushplified uye inodhonza iyo mos tube yekuita shanduko yekuchinja, kuitira kuti iyo indinors iyo Inductor, kuitira kuti mumwe mugumo weInductor anogona kuwana acTOGE.

LC Oscillation uye Dunhu Rekunze

Output voltage mhinduro: Kana mutoro wacho uchishanda, iyo sampling voltage inodyara kudzoka kudzikamisa iyo voltage kubuda kweiyo ini inverter.

Basa
Iyo Inverter inoshandura DC simba (bhatiri, bhatiri rekuchengetedza) kuita AC simba (kazhinji 220V50HZ SINE kana Scarta wave). MuMitemo yaLayman, inverter chishandiso chinoshandura zvakananga zvazvino (DC) kuita kuchinjika zviripo (ac). Iyo ine yeiyo inverter Bridge, dzora pfungwa uye firita dunhu.
Zvichingoisa, anvertter is emagetsi mudziyo unoshandura yakaderera-voltage (12 Nekuti 220 Volts AC Simba rinowanzo raramo mune DC simba rekushandisa, uye basa romunyori rakapesana, saka zita racho. Munguva ye "kufamba", nhare mbozha, nhare mbozha, nharembozha uye varaidzo. Paunenge uchifamba, kwete chete voltage zvakananga zvazvino zvinodikanwa kubva pamabhatiri kana mabhatiri ekuchengetedza, asi zvakare mazana maviri-volt kuchinjisa zvazvino, izvo zvakakosha muhupenyu hwezuva nezuva. Vasinganeti vanogona kusangana neizvi zvinodiwa.
