Chii chinonzi inverter?

Iyo inverter iDC kuenda kuAC transformer, inova nzira yekuchinja voltage ne converter. Iyo converter inoshandura AC voltage ye power grid kuita stable 12V DC output, ukuwo iyo inverter ichishandura 12V DC voltage output ne adapter kuita high-frequency high-voltage AC; zvikamu zvese zvinoshandisawo tekinoroji inoshandiswa zvakanyanya ye pulse width modulation (PWM). Chikamu chikuru iPWM integrated controller, iyo adapter inoshandisa UC3842, uye iyo inverter inoshandisa TL5001 chip. Voltage range yekushanda yeTL5001 i3.6~40V, uye ine error amplifier, regulator, oscillator, PWM generator ine dead zone control, low voltage protection circuit uye short circuit protection circuit.

Chikamu cheInput interface: Chikamu cheInput chine masaini matatu, 12V DC input VIN, functional enable voltage ENB uye Panel current control signal DIM. VIN inopihwa neAdapter, uye ENB voltage inopihwa neMCU pamotherboard, uye kukosha kwayo i0 kana 3V. Kana ENB=0, inverter haishande, uye kana ENB=3V, inverter inenge iri mumamiriro ekushanda akajairwa; uye DIM voltage inopihwa nemotherboard, uye variation range yayo iri pakati pe0 ne5V. Divi values ​​​​dzakasiyana dzinodzoserwa kumagumo efeedback ePWM controller, uye current inopihwa neinverter kumutoro ichave yakasiyanawo. Kana DIM value iri diki, current output inowedzerwa neinverter.

Chinotangira magetsi: Kana ENB yakakwira, magetsi akawanda anobuda kuti abatidze chubhu yemwenje yekumashure yePanel.

PWM controller: Ine mabasa anotevera: internal reference voltage, error amplifier, oscillator nePWM, dziviriro ye overvoltage, dziviriro ye undervoltage, dziviriro ye short circuit, uye transistor inobuda.

Kuchinja kweDC: Dunhu rekuchinja voltage rinoumbwa nechubhu yeMOS switch uye inductor yekuchengetedza simba. Pulse yekupinda inowedzerwa ne amplifier ye push-pull uye inotyaira chubhu yeMOS kuti iite switching action, kuitira kuti DC voltage ichaje uye ibudise inductor, kuitira kuti rimwe divi re inductor rigone kuwana AC voltage.

Kutenderera kweLC uye kubuda kwemagetsi: chengetedza voltage ye1600V inodiwa kuti rambi ritange, uye deredza voltage kusvika ku800V mushure mekunge rambi ratanga.

Mhinduro yevoltage inobuda: kana mutoro uchishanda, voltage yesampuru inodzoserwa kuti igare yakasimba voltage inobuda yeI inverter.

Iyo inverter inoshandura simba reDC (bhatiri, bhatiri rekuchengetera) kuita simba reAC (kazhinji 220v50HZ sine kana square wave). Mukutaura kwevanhuwo zvavo, inverter chishandiso chinoshandura direct current (DC) kuita alternating current (AC). Ine inverter bridge, control logic uye filter circuit.
Muchidimbu, inverter mudziyo wemagetsi unoshandura simba remagetsi mashoma (12 kana 24 volts kana 48 volts) kuita simba remagetsi e ...
