phocos PWM uye MPPT Charge Controllers
Musiyano pakati pePWM & MPPT
PWM: Pulse-Width Modulation
MPPT: Maximum Power Point Tracking
PWM neMPPT ndiwo marudzi maviri akasiyana ezvekuchaja nzira dzinogona kushandiswa nesolar kuchaja mabhatiri kubva kune solar array/panel. Ese ari maviri matekinoroji anoshandiswa zvakanyanya muiyo off-grid solar indasitiri uye ese ari maviri makuru sarudzo dzekuchaja bhatiri rako nemazvo. Sarudzo yekushandisa PWM kana MPPT regulation haina kungobva pakuti ndeipi nzira yekuchaja simba "iri nani" pane imwe. Uyezve, zvinosanganisira kuona kuti ndeupi rudzi rwemutongi anoshanda zvakanyanya mukugadzira system yako. Kuti tinzwisise mutsauko uripo pakati pePWM neMPPT kuchaja, ngatitangei tatarisa pane yakajairika simba curve yePV pani. Iyo curve yemagetsi yakakosha nekuti inotaura inotarisirwa kugadzirwa kwemagetsi kwepaneru zvichienderana nemubatanidzwa voltage ("V") uye yazvino ("Ini") inogadzirwa nepaneru. The optimal ratio of current to voltage kugadzira simba rakawanda rinozivikanwa se "Maximum Power Point" (MPPT). Iyo MPPT ichachinja zvine simba mukati mezuva rose zvichienderana nemamiriro eradiation.
- Kazhinji kazhinji iwe unogona kuwana iyo magetsi curve yePV pani yako pane dhetabheti yechigadzirwa.
PWM Charge Controllers
Pulse-Width Modulation (PWM) inotanga kushanda kana bhatiri bhangi razara. Panguva yekuchaja, mutongi anobvumira yazvino seyazvino iyo PV pani / dhizaini inogona kuburitsa kuitira kuti isvike kune chinangwa vol.tage yemhosva stage mutongi ari mukati. Kana bhatiri rasvika ichi chinangwa voltage, mutongi wechaja anokurumidza kushandura pakati pekubatanidza bhatiri bhangi kune mapaneru array uye kubvisa bhatiri bhangi, iro rinoronga bhatiri vol.tage kuibata nguva dzose. Uku kukurumidza kuchinjika kunodaidzwa kuti PWM uye inoita kuti bhatiri rako bhangi richajirwe zvakanaka uku richiridzivirira kubva pakuchajwa nePV panel/array.
PWM ma controller anozoshanda padhuze neakanyanya simba poindi asi kazhinji zvishoma "pamusoro" payo. An exampLe operating range inoratidzwa pasi apa. 
MPPT Charge Controllers
Maximum Power Point Tracking inoratidzira hukama husina kunanga pakati pePV array nebhatiri bhangi. Iyo isina kunanga yekubatanidza inosanganisira DC / DC voltage converter inogona kutora yakawandisa PV voltage uye woishandura kuita yekuwedzera ikozvino pane yakaderera voltage pasina kurasikirwa nesimba.
MPPT ma controllers anoita izvi kuburikidza neadaptive algorithm inoteedzera iyo yakanyanya simba poindi yePV array uyezve inogadzirisa iyo inouya vol.tage kuchengetedza huwandu hunobudirira hwesimba rehurongwa. 
Zvakanakira uye Zvakashata zveMarudzi Maviri eVatongi
| PWM | MPPT | |
| Pros | 1/3 - 1/2 mutengo weMPPT controller. | Kunyanya kuchaja kushanda zvakanaka (kunyanya munzvimbo dzinotonhorera). |
| Upenyu hurefu hunotarisirwa nekuda kwezvikamu zvishoma zvemagetsi uye kushomeka kwekupisa. | Inogona kushandiswa ne60-cell panels. | |
| Saizi diki | Kugona kuwedzeredza array kuti ive nechokwadi chekuchaja kwakaringana mumwedzi yechando. | |
| Cons | PV arrays nemabhangi ebhatiri anofanira kunge akakurisa zvakanyanya uye angangoda ruzivo rwekugadzira. | 2-3 nguva inodhura kupfuura inofananidzwa PWM controller. |
| Haikwanise kushandiswa nemazvo ne60- cell panels. | Upenyu hupfupi hunotarisirwa nekuda kwezvimwe zvikamu zvemagetsi uye kushushikana kukuru kwekupisa. |
Nzira yekusarudza mutongi akakodzera kune yako system
Pane peji rinotevera iwe unowana infographic flow chart iyo ichakubatsira iwe kuona kuti ndeupi rudzi rwechaji controller yakanakira yako chaiyo purojekiti. Kunyange paine zvimwe zvakawanda zvinosiyana zvekufunga nezvazvo pakusarudza kuti ndeupi controller anonyatsokodzera system yako, iyo infographic iri papeji rinotevera ine chinangwa chekutora zvimwe zvakavanzika kunze kwechisarudzo nekugadzirisa zvinhu zvakanyanya kukosha zvinofanirwa kutariswa pakuita. sarudzo yako. Kuti uwane rumwe rubatsiro, ndapota inzwa wakasununguka kubata dhipatimendi redu rehunyanzvi pa: tech.na@phocos.com.
