Inverter nigikoresho cyo guhindura imbaraga kigizwe nibikoresho bya semiconductor, bikoreshwa cyane cyane muguhindura ingufu za DC mumashanyarazi.Mubisanzwe bigizwe no kuzamura umuzenguruko hamwe na inverter ikiraro kizunguruka.Kuzamura umuzenguruko bizamura imbaraga za DC ya selile yizuba kuri voltage ya DC isabwa kugirango igenzure ibisohoka;inverter ikiraro cyumuzunguruko gihindura ingufu za DC zongerewe imbaraga mumashanyarazi ya AC hamwe numurongo rusange uhwanye.
Inverter, izwi kandi nk'umucungamutungo, irashobora kugabanywa mu gutanga amashanyarazi yigenga no gukoresha imiyoboro ya gride ukurikije ikoreshwa rya inverter muri sisitemu yo kubyara amashanyarazi.Ukurikije uburyo bwo guhindura imiyoboro, irashobora kugabanywamo iniverisite ya kare, intambwe yo guhinduranya intambwe, sine wave inverter, hanyuma igahuza ibyiciro bitatu.Kuri inverter zikoreshwa muri sisitemu ihujwe na gride, zirashobora kugabanwa muburyo bwa transformateur-inverter na transformateur-inverter ukurikije niba hari transformateur.Ibyingenzi byingenzi bya tekinike ya sunvolvolic inverter ni:
1. Ikigereranyo gisohoka voltage
Inverteri ya Photovoltaque igomba gushobora gusohora agaciro kagereranijwe mumashanyarazi yemerewe guhindagurika kumurongo winjiza wa DC.Mubisanzwe, iyo ibipimo byasohotse byapimwe ni icyiciro kimwe 220v hamwe nicyiciro cya gatatu 380v, ihindagurika rya voltage ryerekanwe kuburyo bukurikira.
.
(2) Iyo umutwaro uhinduwe gitunguranye, gutandukana kwa voltage ntibirenga ± 10% byagaciro kagenwe.
.
.
(5) Gutandukana kwinshuro za inverter zisohoka AC voltage igomba kuba muri 1% mugihe gisanzwe cyakazi.Ibisohoka voltage inshuro zerekanwe mubisanzwe byigihugu Gb / t 19064-2003 bigomba kuba hagati ya 49 na 51hz.
2. Umutwaro w'ingufu
Ingano yimitwaro yingufu yerekana ubushobozi bwa inverter yo gutwara umutwaro wa inductive cyangwa umutwaro wa capacitive.Ukurikije imiterere ya sine, ibintu bitera imbaraga ni 0.7 kugeza 0.9, naho agaciro kagereranijwe ni 0.9.Mugihe cyingufu zimwe zipakurura, niba imbaraga za inverter ziri hasi, ubushobozi bukenewe bwa inverter buziyongera, bigatuma ibiciro byiyongera.Mugihe kimwe, imbaraga zigaragara zumuzunguruko wa AC ya sisitemu ya Photovoltaque iriyongera, kandi numuyoboro wumurongo uriyongera.Niba ari binini, igihombo kiziyongera byanze bikunze, kandi imikorere ya sisitemu nayo izagabanuka.
3. Ikigereranyo gisohoka kigezweho hamwe nubushobozi bwo gusohora
Ibipimo bisohoka byerekana ibyasohotse byasohotse muri inverter murwego rwerekanwe ibintu byerekana imbaraga, igice ni a;ubushobozi bwo gusohora ibicuruzwa bivuga ibicuruzwa biva mu bipimo byasohotse hamwe n’ibisohoka byasohotse muri inverter mugihe ibintu bisohoka ari 1 (ni ukuvuga umutwaro urwanya umutwaro), igice ni kva cyangwa kw.
