I-Inverter iyithuluzi lokulungiswa kwamandla elihlanganiswe namadivayisi we-semiconductor, asetshenziselwa ikakhulukazi ukuguqula amandla we-DC abe amandla e-AC. Ngokuvamile kwakhiwa umjikelezo wokukhulisa kanye nomjikelezo webhuloho le-Inverter. I-Boost Circuit ikhulisa i-VC Voltage ye-DC yeseli elanga kuya e-DC voltage edingekayo yokulawulwa kokukhishwa kwe-Inverter; I-Inverter Bridge Circuit iguqula i-voltage ekhuphukile ye-DC ibe ngumuntu osebenza ngokufanayo ngokufanayo.
I-inverter, eyaziwa nangokuthi i-Power Regulator, ingahlukaniswa ngokuhlinzekwa kwamandla okuzimele kanye nokusetshenziswa okuxhunywe ngegridi ngokuya ngokusetshenziswa kwe-inverter kuhlelo lokuGunga Lwesizukulwane sePhotovoltaic. Ngokusho kwe-Waveform Modration Megamution, ingahlukaniswa ibe yi-inverter ye-skwele yama-wave, isinyathelo segagasi inverter, i-inserter ye-sine wave, futhi ihlanganiswe nesigaba sesigaba ezintathu. Kwabampofu abasetshenziswa ezinhlelweni ezixhumeke nge-grid, zingahlukaniswa zaba ama-transformer-hlobo amandla ama-inverters kanye nabaguquli abancane ngokusho ukuthi kukhona i-transformer. Amapharamitha aphambili obuchwepheshe be-solar Photovoltaic inverter yile:
1. Ukulinganiswa kwamandla akhiqizwayo
I-Photovoltaic Inverter kufanele ikwazi ukukhipha inani le-voltage le-voltable ngaphakathi kohlu lokusesha oluvumelekile lwe-VC Voltage ebekiwe. Ngokuvamile, lapho i-voltage ekhiqizwe okulinganiselwe ingu-220v kanye nesigaba esingu-380v 380v, ukuphambuka kokuguquguquka kwamandla kagesi kuchaziwe ngale ndlela elandelayo.
(1) Uma usebenza esimweni esiqinile, ngokuvamile kudingeka ukuthi ukuphambuka kokuguquguquka kwamandla kagesi akudluli ku-
(2) Lapho umthwalo ushintshwa kungazelelwe, ukuphambuka kwamandla kagesi akudluli ku- ± 10 10% yenani elikalwe.
.
.
(5) Ukuphambuka imvamisa ye-inverter actput ac voltage kufanele ibe ngaphakathi kwe-1% ngaphansi kwezimo ezijwayelekile zokusebenza. Imvamisa yeVoltage Volfage echazwe kuNational Standard GB / T 19064-2003 kufanele ibe phakathi kuka-49 no-51Hz.
2. Layisha i-Power Factor
Usayizi we-Load Power Factor ukhombisa ikhono le-inverter elizophatha umthwalo ongahambi kahle noma umthwalo we-capacitive. Ngaphansi kwesimo segagasi le-sine, i-Load Power Factor ingu-0,7 kuye ku-0.9, kanye nenani elikalwe ngu-0.9. Endabeni yamandla athile okulayisha, uma isici samandla esise-Inverter siphansi, umthamo odingekayo we-inverter uzokwanda, okuholela ekwandeni kwezindleko. Ngasikhathi sinye, amandla abonakalayo wesekethe ye-AC yohlelo lwe-Photovoltaic akhuphuka, kanye nokwenyuka kwamanje kwenhlangano. Uma kukhulu, ukulahleka kuzokhuphuka nakanjani, futhi ukusebenza kahle kohlelo kuzokwehla.
3. Ukukhishwa okulinganiselwe okulinganiselwe futhi kulinganiselwe amandla okuphuma
Ukukhishwa okulinganiselwe kubhekisele kulokho okukhiqizwe okukhiqizwe okukhona kwe-inverter ngaphakathi kobubanzi be-Load Power factor ebekiwe, iyunithi yilo; Umthamo wokukhishwa okulinganiselwe ubhekisa kuMkhiqizweni Wokukhiqizwa okulinganiselwe okulinganiselwe kanye nokukhishwa okulinganiselwe okukhona kwe-inverter lapho umphumela wamandla okuhambisa uwukuthi 1 (okungukuthi i-pure wokumelana nokuthula), iyunithi yi-KVA noma kw.
