Zita rakazara remicro-inverterndiyo micro solar grid-yakasungwa inverter.Inonyanya kushandiswa mu photovoltaic magetsi ekugadzira masisitimu uye kazhinji inoreva kune inverters uye module-level MPPTs ine chiyero chesimba chisingasviki 1500W.Micro-invertersidiki muhukuru zvichienzaniswa neyakajairwa centralized inverters.Micro-invertersinvert imwe neimwe module.Chakanakira ndechekuti imwe neimwe module inogona kudzorwa yakazvimirira neMPPT.Izvi zvinovandudza zvakanyanya kushanda kwese.Panguva imwe,micro-invertersinogona kudzivirira matambudziko epamusoro DC voltage, kushomeka kwechiedza, uye mbiya mhedzisiro yepakati inverters.
Micro-invertersgadzirisa kuunganidzwa kwesimba rezuva pane mapaneru ega ega kuti uwedzere kushanda kweiyo solar kuisirwa, pane kushanda muhurongwa hwese senge central inverter.Munguva yakapfuura, nzira dzakaoma dzekutonga dzinoshandiswa kuve nechokwadi chekushanda kwepamusoro panguva yekuunganidza kwezuva kwakawedzera mari uye kuderedza kutora kwe micro-inverters.Yakabatanidzwa yedunhu uye processor-yakavakirwa mhinduro zvese zvakaomarara uye zvinodhura-zvinoshanda kubata iyo logic kutonga kwe.micro-inverterdesigns.Akasiyana-siyana magetsi ekudzora uye maregulator anopawo anopindirana mhinduro dzekugadzira simba kubva kuDC inobuda yemapanera ezuva.
Muchidimbumicro-inverterdhizaini, inopindirana inoshanda yakasungirirwa flyback inverter inovandudza yakaderera voltage DC voltage kubva kune solar panel uye yakakwira voltage AC waveform inodiwa negridi.
Kufanana nekugadzira magetsi emagetsi,micro-inverterkugadzira kunoda maitiro akasiyana-siyana ekuvandudza kushanda uye kuvimbika.An interleaved flyback topology inoshandiswa, iyo inobatsira kuderedza rms ripple current kuburikidza navo, nekudaro kuwedzera hupenyu hwe electrolytic capacitor mumagadzirirwo aya.Pamusoro pezvo, kushandiswa kweanoshanda clamping matekiniki anobvumira yakakwirira yepamusoro yebasa kutenderera, ichigonesa kushandiswa kweyepamusoro matende reshiyo.Izvi zvinogona kuderedza zvakanyanya mutoro wazvino padivi rekutanga uye nevoltage padivi rechipiri.
Kuti ive nechokwadi chekubuda kwesimba rakakura, iyo inverter inofanirwa kukwanisa kupindura kunemicro-inverter'skudzora pfungwa.Iyi pfungwa yakagadzirirwa kuchengetedza voltage uye ikozvino yekushandura iri padyo sezvinobvira kune inodiwa maitiro anogadzirwa neMPPT algorithm.Kunyanya kukosha, grid-yakabatanamicro-invertersinofanira kukwanisa kubvisa kubva pagridi kana pakaitika simba.Aya maficha ekudzivirira kukanganisa, zvakare, anoda kuti inverter ive neinenge yakawandisa uye yekuona undervoltage.
Magadzirirwo emicro-invertersinoisa kutonga, kushandura simba uye zvinodikanwa zvinogoneka izvo zvakaganhurira kushandiswa kwavo kwakapararira munguva yakapfuura.Zvisinei, nekuwanda kwezvigadziriso zvakabatanidzwa, vagadziri vanogona kushandisa zvakasiyana-siyana zvakakodzera michina.Nepo ma processor akazvipira anogona kupa iyo yepamusoro kudzora maficha uye MPPT mashandiro anodiwamicro-inverters, magadzirirwo edanho rekushandura simba anoda zvishandiso zvinogona kuendesa zvakachengeteka uye zvinobudirira kushanda uye kushanda kunodiwa kune grid.Iine huwandu hwakasiyana hwekubatanidza switching regulators uye PMICs iripo, mainjiniya anogona kugadzira inoshanda, inodhura-inoshanda-inoshanda simba rekushandura matanho mune micro-inverter magadzirirwo.
