Parizvino, China's PhotoVoltaic Simba Chizvarwa Chinyorwa chinonyanya kugadzirwa dc system, iyo yekubhadhara simba emagetsi inogadzirwa nebhatiri reSolar, uye bhatiri rinopa zvakananga simba kune mutoro. Semuenzaniso, imba yemuridzi weSourling system muNorthwest China uye microwave Station Simba Supply System kure kure neGrid ndeye ese DC system. Iyi mhando yehurongwa ine chimiro chakareruka uye mutengo wakaderera. Nekudaro, nekuda kweiyo yakasiyana mutoro DC voltages (yakadai se12V, 24v, 24v, 48. Zvakaoma kuita seristist Zvakaoma kuti iyo fotovoltaic simba kupa magetsi kuti apinde mumusika sechigadzirwa. Mukuwedzera, chizvarwa chemagetsi chemagetsi chinozopedzisira chazadzisa chishandiso-chakabatana kushanda, izvo zvinofanirwa kutora mutambo wemusika wemusika. Mune ramangwana, AC Phyevoltaic Simba Zvigadzirwa Systems ichava iyo huru yeiyo PhotosVoltaic Simba Chizvarwa.
Izvo zvinodiwa zveThosevoltaic Simba Chizvarwa System ye Inverter Power Supply
Iyo photovoltaic simba rechizvarwa system uchishandisa AC SIMBA KUSVIRA KWEMAHARA: MAHARA Photovoltaic ine zvakakwirira zvinodiwa kune vevatengi:
1. Kubudirira kwakanyanya kunodiwa. Nekuda kwemutengo wakakwira wemasero emusaruri parizvino, kuitira kuti uwedzere kushandiswa kwemasero eSolar uye kugadzirisa maitiro ekushanda kwesimba
2. Kukwikwidza kwakanyanya kunodiwa. Parizvino, zvigadzirwa zveMovevoltaic Simba zvinonyanya kushandiswa munzvimbo dziri kure, uye zviito zvakawanda zvemagetsi hazvina kutarisirwa uye chengetwa. Izvi zvinoda kuti muongorori kuve neyakajairwa dunhu redunhu, uye inoda kuti inverter yekudzivirirwa kwakasiyana, yakadai sekudzivirirwa kapfupi,
3. Iyo DC yekuisa voltage inodiwa kuti uve nehuremu hwakawanda hwekuchinja. Sezvo iyo terminage voltage yebhatiri ichichinja nemutoro uye kusimba kwezuva, kunyangwe iyo bhatiri racho rakakosha, iyo bhatiri voltage inoshanduka nekuchinja kwebhatiri uye kuramba kwemukati. Kunyanya kana bhatiri iri kuchembera, volismal voltage inosiyana zvakanyanya. Semuenzaniso, voltage terminage yegumi nemaviri vanogona kusiyana kubva ku10 v kusvika 16 v. Izvi zvinoda kuti inverter yekushanda kune yakajairika yekuvhenekera mukati meiyo yekuvhenekera kweiyo acctage voltage.
4 Izvi zvinodaro nekuti pakati nepakati uye yakakura-kugona masisitimu, kana mraba tsaona simba rinoshandiswa, kubuda kuchangoita zvimwe zvinhu zvealmonic, uye zvakakwirira zvealmonics zvichawedzera kuwedzera kurasikirwa. Mazhinji maficha emifananidzo yechizvarwa zvinoremerwa nekutaurirana kana chombo chishandiso. Midziyo ine zvakapfuura zvinodiwa pamhando yeiyo simba grid. Kana iyo svikiro uye yakakura-capacity photovoltaic simba marongero akabatana neyechidhirowa, kuitira kuti udzivise kusvibiswa kweruzhinji, iyo inverter inodikanwa zvakare kuti ubudise mudenga wachi iripo.
Iyo inverter inoshandura zvakananga zvazvino mukuchinja zvazvino. Kana iyo yakananga yazvino voltage yakaderera, inowedzera nekuchinja kwechinguva chizvino transformer kuti uwane imwe nzira yekunyanyisa yekuvanda uye frequency. Kune makuru-emagetsi evers, nekuda kweiyo yakakwira DC bhazi voltage, iyo AC kubuda kazhinji haidi shanduko yekuwedzera kuwanda kusvika ku20V. Mune svikiro uye diki-kugona-masangano Pakati nepakati uye zvidiki-kugona-masters zvinowanzo kusanganisira push-dhonza matunhu emukati, zvizere-bhiriji matunhu uye yakakwira-frequency inowedzera masendimita. Push-dhiza Matunhu anobatanidza neyakagwinya plug yeshanduro yezvinhu zvakanaka, uye drive uye shanduko yedzinza zvine chekuita nekukasira, zvoga zvingaitika razvino riripo, nekudaro inovandudza kuvimbika kwedunhu. Iko kukanganisa ndiko kuti iyo transformer yekushandisa yakaderera uye kugona kwekutyaira zvinhu zvine mutsindo murombo.
Iyo yakazara-Bridge Inverter Dunhu rinokurisa zvikanganiso zveDunhu rekusundira-dhiri. Iyo Simba Transistor inogadzirisa iyo yekubuda pulse upfu hwakakura, uye kukosha kunobudirira kweiyo ACPUT AC AC Voltage zvinoenderana nenzira kwayo. Nekuti dunhu racho rine chiuno chemahara, kunyangwe kune mitoro inonakidza, iyo yekuburitsa maltage voltage harizokanganiswi. Iko kukanganisa kwedunhu iri ndekwekuti simba rekutengesa kwesimba uye rakaderera maoko vasingagovani pasi, saka dunhu rekutyaira rekutyaira kana kuwanikwa kwesimba rakazvimirira rinofanira kushandiswa. Uye zvakare, kuitira kudzivirira kuitwa kwakawanda kweiyo yepamusoro uye yepasi bhiriji yebridge, redunhu rinofanira kugadzirwa kuti rirege uye rinobva ratenderwa, kureva nguva yakafa inofanira kuiswa, uye chimiro chedunhu chinofanira kuomarara.
Iyo yakabuda yakaburitswa-dhiramu dunhu uye yakazara-bhiri-bhiriji rinofanira kuwedzera nhanho-up transformer. Nekuti nhanho-kumusoro shanduko yakakura muhukuru, yakaderera mukubudirira, uye nekuvandudzwa kwemagetsi mashandiro ezvekutendeuka kwekushandurwa. Iyo yekumberi-nhanho inowedzera dunhu reiyi inverter Circuit inogamuchira push-dhonza chimiro, asi iyo yekuvandudza frequency iri pamusoro pe 20khz. Iyo inosimudzira transformer inogamuchira yakakwira-frequency magnetic core zvinhu, saka idiki muhukuru uye chiedza chakaremerwa. Mushure mekupindurwa-frequency
Iine chimiro chedunhu ichi, simba revanyori rinovandudzika zvikuru, kusava-muripo wemukati kwakadzikira kwakaenzana, uye kugona kwacho kunovandudzwa. Iko kukanganisa kwedunhu ndekwekuti dunhu rakaoma uye kutevedzana kwakaderera pane matunhu maviri matatu.
Dzora Dunhu reInverter Circuit
Dunhu hombe revataurwa pamusoro-zvataurwa pamusoro pevose vanofanirwa kuzivikanwa nedunhu rekutonga. Kazhinji, pane nzira mbiri dzekudzora: Square wave uye yakanaka uye isina kusimba wave. Iyo Inverter Power Supply Dunhu nekwere Wave Kubuda kwakareruka, kwakaderera mumutengo, asi zvakaderera mukubudirira uye hombe mune zvealmonic zvikamu. . Sine Wave Kubuda ndiko kusimudzira maitiro evanobatanidzwa. Nekuvandudzwa kwehunyanzvi hwemachinda, micropfecessors nePWM mabasa anobudawo. Naizvozvo, iyo inverter tekinoroji yeSine Wave Kubuda kwakakura.
1. Vanopinda vane mraba wave Dzidzira yakaratidza kuti kushandiswa kweSG3525 kwakabatanidzwa zvapera mashandisirwo uye kushandiswa kwesimba masimba sekuchinja zvinhu zvine simba kunogona kuwana zvakanyanyisa kuita uye mutengo wevarwi. Nekuti SG3525 ine kugona kwekutyaira zvakananga magetsi ekugona kugona uye ane yemukati rezita uye basa rekudzivirira uye rinodzivirirwa.
2.. MP 16 uye PI C 3 c 73 C.3 Munguva yakafa, shandisa iyo Intel Company's 80 C 196 MC Kuti Uzive Sine Wave Dunhu Rekubuda,
Kusarudzwa kwesimba mashandiro emidziyo mune huru dunhu reiyo inverter
Kusarudzwa kwezvinhu zvakakosha zvezvinhu zveinverteryakakosha. Parizvino, zvinhu zvakanyanyisa kushandiswa zvinoshandiswa zvinosanganisira Darling Power Transisters (BJT), Simba Ression Ers Transistors (Mos-F et), Igedhi reGedhi Sitashi (Igb). T) uye tendeuka-kubva kune yako (gto), etc. Izvi zvinodaro nekuti iyo-yenyika kudzikisira kweMos Fet kuwedzera kweVoltage, uye ig bt iri mumamiriro ezvinhu epakati inowana mukana wakakura, nepo mune yakakura-kugona (pamusoro pegirini, gotos inowanzo shandiswa sezvinhu zvesimba.
