Masisitimu ekuchengetedza magetsi chinhu chakakosha chemazuva ano anovandudzwa simba masisitimu. Iwo anoshandiswa zvakanyanya sezvo achinyatso dzikisa kutambisa simba uye kuvandudza kushanda kwese kwesimba masisitimu. Nekuda kwekudyidzana pakati pemabhatiri uye gidhi remagetsi, vashanduri vanodiwa kuita AC-DC kutendeuka uye kugonesa bidirectional simba kuyerera. Pamusoro pezvo, vashanduri vanoita basa rakakosha mumasisitimu ekuchengetedza simba nekudzora simba kuburikidza nekudzora ukuru uye kutungamira kwazvino, zvichiita kuti peak shave uye kuzadza mupata kuwedzera simba rekushandisa simba, pamwe nekupa kuchengetedzwa kwekuremerwa kuve nechokwadi chekuchengetedza system.
Pakati pe rectifier circuit uye converter circuit, aDC-LINK capacitorinodiwa pakutsigira ikozvino uye kusefa. Basa rayo rekutanga nderekutora kupuruzira kwakakwira paDC-LINK bhazi, kudzivirira yakakwira pulse voltage kubva pakugadzirwa kweimpedance yeDC-LINK. Izvi zvinodzivirirawo kuguma kwemutoro kubva pakukanganisa kwe overvoltage.
YMIN capacitors ine zvinotevera maitiro mumunda wekushandura
01. High Capacity
Iyo DC-Link capacitor inochengetedza simba remagetsi, ichiigonesa kuti ipe simba rinoenderera kune inoshandura sisitimu panguva yakakosha grid voltage kushanduka kana kudzimwa kwemagetsi, kuve nechokwadi chekushanda kwakajairika kwehurongwa. Pamusoro pezvo, kana iyo inoshandura sisitimu ichida huwandu hukuru hwesimba, iyo DC-Link capacitor inogona kukurumidza kuburitsa yakachengetwa simba kuti isangane nezvido zvenguva pfupi. Mune inductive mitoro yakadai semotor, iyo capacitor inopawo reactive simba muripo, inodzikamisa voltage, uye inovandudza mota. Izvi zvinoita basa rakakosha mukusimudzira kushanda zvakanaka kwehurongwa uye kugadzikana.
02. Ultra-High Voltage Resistance
YMIN capacitors, ine yavo yekupedzisira-yakakwirira voltage kuramba, inogona zvakare kushanda sezvinhu zvinodzivirira. Panguva yekushandura kwekushandura, vanochengetedza zvinhu zvemagetsi zvinonzwisisika kubva pakukuvadzwa kunokonzerwa nemagetsi spikes. Izvi zvinoita kuti magetsi ekuchengetedza magetsi ape yakagadzikana voltage uye frequency rutsigiro kune gidhi remagetsi, kuve nechokwadi chekushanda kwakavimbika kwehurongwa.
03. High Current Surge Resistance
YMIN capacitors inonyatso tora yakakwira pulse currents inogadzirwa neinoshandura paDC-Link end, ichigonesa chaiyo kubuda simba regulation kuburikidza nekutonga kwazvino. Izvi zvinoita kuti shanduko inosangana nezvinodiwa zveakasiyana siyana uye inopa yemhando yepamusoro AC kubuda. Munguva yekunyorova-yekutanga maitiro evashanduri, YMIN capacitors inoumba chikamu chedunhu rekuchaja, ichibatsira kudzivirira yakawandisa kukanganisa pane yekupinza magetsi uye mutoro.
04. Hupenyu Hurefu
YMIN capacitors, inogadzirwa kuburikidza neakamisikidzwa maitiro uye akaiswa pasi pekuomesera kusati kwaburitsa kuyedzwa, inoratidzira yakakwira density uye yakanakisa ikozvino kushamba kuramba. Unhu uhwu hunoita kuti ma converter mumasisitimu ekuchengetedza simba ashande zvakadzikama kwenguva yakareba, achidzikisa kutadza uye mari yekugadzirisa.

Basa, zvakanakira uye maitiro esnap-in aluminium electrolytic capacitorsin converter PCS application:
High voltage resistance:High voltage capacitor inokwanisa kubata mafungu akakura uye kushingirira kuvhunduka kunokonzerwa nekukasika high voltage kana kusimuka kwemutoro.
Yakaderera yakaenzana yakatevedzana kuramba (ESR) uye yakakwira ripple ikozvino kushivirira:Iine yakaderera ESR uye yakakwira ripple ikozvino kuramba, iyo yakaderera ESR ye capacitor inobatsira kuderedza kushanduka kwemagetsi uye kugadzirisa kugadzikana kwehurongwa.
Hupenyu hurefu uye kuvimbika kwepamusoro:Kudzivirira kwekushisa kwepamusoro uye hupenyu hurefu hunovimbisa kushanda kwayo kwakagadzikana munzvimbo dzakaoma. Izvi zvakakosha kune kwenguva yakareba isingapindirwe simba rekuchengetedza simba senge simba remhepo uye photovoltaic simba rekugadzira.
Yakanaka thermal manejimendi maitiro:Zvinonyatso bvisa kupisa kudzivirira kupisa kubva pakukonzera kuderera kwekuita kana kutadza.
Volume optimization:High capacity density uchitora nzvimbo shoma.
