Inverter yopangidwa ndi kampaniyi

Inverter, yomwe imadziwikanso kuti mphamvu yamagetsi, yoyendetsa mphamvu, ndi gawo lofunika kwambiri la photovoltaic system.Ntchito yofunika kwambiri ya photovoltaic inverter ndiyo kutembenuza mphamvu ya DC yopangidwa ndi solar panel mu mphamvu ya AC yogwiritsidwa ntchito ndi zipangizo zapakhomo.Magetsi onse opangidwa ndi gulu la solar amatha kutumizidwa kunja kudzera mu chithandizo cha inverter.kudutsa mlatho wathunthu, nthawi zambiri amatengera purosesa ya SPWM kudzera mukusintha, kusefa, kukwezedwa kwamagetsi, ndi zina zambiri, kuti apeze sinusoidal AC system yofananira ndi kuyatsa. Kuthamanga kwafupipafupi, kuvotera kwa ogwiritsira ntchito mapeto.Ndi inverter, batri ya DC ingagwiritsidwe ntchito kupereka mphamvu ya AC kwa chipangizocho.

Dongosolo lamagetsi la solar AC lili ndi ma solar panel, chowongolera chowongolera, inverter ndi batri;Dongosolo lamagetsi la solar DC silimaphatikizapo inverter. Njira yosinthira mphamvu yamagetsi ya AC kukhala mphamvu yamagetsi ya DC imatchedwa rectification, dera lomwe limamaliza ntchito yokonzanso limatchedwa rectifier circuit, ndipo chipangizo chomwe chimazindikira njira yokonzanso ndikukonzanso. Chomwe chimadziwika kuti chipangizo cha rectifier kapena rectifier.Mofananirako, njira yosinthira mphamvu yamagetsi ya DC kukhala mphamvu yamagetsi ya AC imatchedwa inverter, dera lomwe limamaliza ntchito ya inverter limatchedwa inverter circuit, ndi chipangizo chomwe chimazindikira njira ya inverter. imatchedwa zida za inverter kapena inverter.
Pakatikati pa chipangizo cha inverter ndi makina osinthira magetsi, kungoti inverter circuit.Njirayi imamaliza ntchito ya inverter kudzera pakuyatsa ndi kutulutsa mphamvu zamagetsi zamagetsi. zoyendetsedwa ndi kusintha chizindikiro cha magetsi.Magawo omwe amapanga ndikuwongolera ma pulses amatchedwa kuti control circuit kapena control circuit.Mapangidwe oyambirira a chipangizo cha inverter, kuphatikizapo inverter yotchulidwa pamwambapa ndi dera loyendetsa, limakhalanso ndi chitetezo dera, linanena bungwe dera, linanena bungwe dera, linanena bungwe dera ndi zina zotero.

Ma inverter apakati amagwiritsidwa ntchito m'makina okhala ndi malo akulu amagetsi amagetsi (> 10kW).Magulu ambiri ofananira a photovoltaic amalumikizidwa ndi kulowetsa kwa DC kwa inverter yapakati yomweyi.Nthawi zambiri, mphamvu yayikulu imagwiritsa ntchito gawo la mphamvu ya IGBT ya magawo atatu, mphamvu yaying'ono imagwiritsa ntchito transistors yamunda, ndikugwiritsa ntchito wowongolera kutembenuka kwa DSP kuti apititse patsogolo mphamvu yamagetsi amagetsi, ndikupangitsa kuti ikhale pafupi kwambiri ndi sinusoidal wave current.Chinthu chachikulu kwambiri ndipamwamba kwambiri. mphamvu ndi mtengo wotsika mtengo.Komabe, chifukwa cha kufanana kwa gulu la photovoltaic gulu ndi shading pang'ono, kumapangitsa kuti pakhale mphamvu komanso mphamvu ya dongosolo lonse la photovoltaic. okhudzidwa ndi kusagwira bwino ntchito kwa gulu linalake la photovoltaic unit.Zotsatira zaposachedwapa zofufuza ndizowongolera kusinthasintha kwa ma vectors apakati, komanso chitukuko cha maulumikizidwe a topological of inverters atsopano kuti apeze mphamvu zambiri pamilandu yolemetsa pang'ono.Pa SolarMax (SolarMax) SowMac) inverter yapakati, bokosi la mawonekedwe a photovoltaic array likhoza kuwonjezeredwa kuti liwunikire mndandanda uliwonse wa gulu la photovoltaic.Ngati gulu la iwo silikugwira ntchito bwino, dongosololi lidzapereka chidziwitso kwa wolamulira wakutali, ndipo likhoza kuyimitsa mndandanda kudzera mu mphamvu zakutali, kuti zisapangitse kulephera kuchepetsa ndi kukhudza ntchito ndi mphamvu zotulutsa mphamvu zonse. photovoltaic system.
