Chii chinonzi solar inverter uye ndeapi mabasa eiyo inverter

Chii chinonzi asolar inverter

Iyo solar AC simba rekugadzira system inoumbwa nesolar panel, charge controller, inverter uyebhatiri ; iyo solar DC simba rekugadzira system haisanganisi iyo inverter. Inverter chinhu chinoshandura simba. Inverters inogona kukamurwa kuita-inofadza oscillation inverter uye yakaparadzana inonakidza oscillation inverter zvinoenderana neiyo excitation nzira. Basa guru ndere kushandura simba reDC rebhatiri kuita simba reAC. Kuburikidza neiyo yakazara-bhiriji redunhu, iyo SPWM processor inowanzo shandiswa kuita modulation, kusefa, kuwedzera voltage, nezvimwe kuwana sinusoidal AC simba rinoenderana neredhiyo yekuvhenekesa, yakayerwa voltage, nezvimwe kune vashandisi vekupedzisira system. Iine inverter, bhatiri reDC rinogona kushandiswa kupa AC simba kumidziyo.

2. Mhando ye inverter

 

(1) Kurongwa nechiyero chekushandisa:

 

(1) Yakajairika inverter

 

DC 12V kana 24V yekupinda, AC 220V, 50Hz yakabuda, simba kubva pa75W kusvika 5000W, mamwe mamodheru ane AC uye DC shanduko, kureva, UPS basa.

 

(2) Inverter/chaja yese-mune-imwe muchina

 

Muizvimhando ye inverter, vashandisi vanogona kushandisa maitiro akasiyana-siyana emagetsi ekugadzirisa AC mitoro: kana pane simba re AC, simba re AC rinoshandiswa kusimbisa mutoro kuburikidza ne-inverter, kana kubhadharisa bhatiri; kana pasina AC simba, bhatiri rinoshandiswa kusimbisa AC mutoro. . Inogona kushandiswa pamwe chete neakasiyana masimba emagetsi: mabhatiri, jenareta, solar panels uye mhepo turbines.

 

(3) Yakakosha inverter yepositi uye telecommunication

 

Ipa emhando yepamusoro 48V inverters yekutumira uye kufonera, kutaurirana. Zvigadzirwa zvayo ndezvemhando yakanaka, kuvimbika kwepamusoro, modular (module is 1KW) inverter, uye ine N+1 redundancy basa uye inogona kuwedzerwa (simba kubva pa2KW kusvika 20KW).

 

4) Special inverter yekubhururuka nemauto

Iyi mhando ye inverter ine 28Vdc yekupinda uye inogona kupa zvinotevera AC zvinobuda: 26Vac, 115Vac, 230Vac. Yayo inobuda frequency inogona kuva: 50Hz, 60Hz uye 400Hz, uye simba rekubuda rinobva pa30VA kusvika 3500VA. Kune zvakare DC-DC inoshandura uye frequency converters yakatsaurirwa kune avhiyesheni.

(2) Kukamurwa nekubuda waveform:

 

(1) Square wave inverter

 

Iyo AC voltage waveform yakabuda ne square wave inverter is square wave. Iyo inverter maseketi anoshandiswa nerudzi urwu rweinverter haana kunyatsofanana, asi chinhu chakajairika ndechekuti dunhu riri nyore uye huwandu hwemagetsi switch machubhu anoshandiswa idiki. Simba rekugadzira rinowanzova pakati pezana watts uye kilowatt imwe. Zvakanakira square wave inverter ndezvi: dunhu riri nyore, mutengo wakachipa uye nyore kugadzirisa. Izvo zvisingabatsiri ndezvekuti sikweya wave voltage ine nhamba huru ye-yakakwirira-yakarongeka maharmonics, ayo anozoburitsa kuwedzera kurasikirwa mumidziyo yemutoro ine iron core inductors kana transformers, zvichikonzera kukanganiswa kwemaredhiyo uye zvimwe zvekutaurirana. Uye zvakare, iyi mhando ye inverter ine zvikanganiso senge isina kukwana voltage regulation renji, isina kukwana kuchengetedza basa, uye ruzha rwakanyanya.

 

2) Nhanho wave inverter

Iyo AC voltage waveform yakabuda nerudzi urwu rwe inverter inverter nhanho wave. Kune mitsetse yakawanda yakasiyana yekuti inverter ione nhanho wave kubuda, uye nhamba yematanho mune yekubuda waveform inosiyana zvakanyanya. Mukana weiyo nhanho wave inverter ndeyekuti yakabuda waveform yakagadziridzwa zvakanyanya kana ichienzaniswa neye square wave, uye yakakwira-yakarongeka harmonic yemukati yakaderedzwa. Kana matanho asvika kupfuura gumi nenomwe, iyo yakabuda waveform inogona kuwana quasi-sinusoidal wave. Paunenge uchishandisa transformerless inobuda, iyo yese kunyatsoshanda yakakwira zvakanyanya. Izvo zvakashata ndezvekuti manera wave superposition wedunhu anoshandisa akawanda emagetsi switch machubhu, uye mamwe ematunhu mafomu anoda akawanda seti eDC magetsi ekuisa. Izvi zvinounza dambudziko kumapoka uye wiring ye solar cell arrays uye kubhadharisa kwakaringana kwemabhatiri. Uye zvakare, iyo staircase wave voltage ichine kumwe kukanganiswa kwepamusoro-frequency kumaredhiyo uye mimwe michina yekutaurirana.

 

(3) Sine wave inverter

 

Iyo AC voltage waveform kubuda ne sine wave inverter ndeye sine wave. Zvakanakira iyo sine wave inverter ndeyekuti ine yakanaka yekubuda waveform, yakaderera kukanganisa, kukanganiswa kudiki kumaredhiyo nemidziyo yekutaurirana, uye ruzha rushoma. Mukuwedzera, ine mabasa ekudzivirira akazara uye nepamusoro pese kunyatsoshanda. Izvo zvisingabatsiri ndezvi: dunhu rinenge rakaoma, rinoda teknolojia yekuchengetedza yakakwirira, uye inodhura.

 

Kurongeka kwemhando nhatu dziri pamusoro apa dze inverters dzinobatsira kune vagadziri uye vashandisi ve photovoltaic systems uye mhepo magetsi emagetsi kuti vaone uye vasarudze inverters. Muchokwadi, ma inverters ane yakafanana waveform achiri akasiyana zvakanyanya maererano nemasimboti edunhu, zvishandiso zvinoshandiswa, nzira dzekudzora, nezvimwe.
