Ingxenye.01 Isingeniso kuma-capacitor efilimu e-DC-Link
Ezisetshenzisweni zamandla amasha kanye nezimoto ezintsha zamandla, ama-capacitor adlala indima ebalulekile ezinhlelweni ezifana nokulawula amandla, ukuphathwa kwamandla kanye nokuguqulwa kwe-DC-AC.
Ikakhulukazi kuma-inverter, ama-capacitor athinta impilo kanye nokusebenza kwesiguquli.
I-inverter ixhumanisa ugesi we-DC ngebhasi le-DC ukuze yakhe i-DC-Link.
Kule nqubo, i-inverter ithola ugesi we-pulse ovela ku-DC-Link bese ikhiqiza ugesi we-pulse kuyo. Lawa ma-voltage anemvamisa ephezulu angabangela umthelela emishinini kagesi.
Ama-capacitor e-DC-Link athuthukisa ukuthembeka nokuphila kwesistimu ngokushelela ukuguquguquka kwamandla kagesi, ukumunca amandla kagesi kanye nokuhlunga ngempumelelo.
Kubalulekile ukukhetha i-capacitor ye-DC-Link efanele, engagcini nje ngokuthuthukisa ukuzinza kwesistimu yesiphelo, kodwa futhi yandisa impilo yesistimu.
Ekusetshenzisweni kwamasimu amasha wamandla okukhulunywe ngawo ngenhla, ama-capacitor e-DC-Link ayisici esibalulekile. Kungakhathaliseki ukuthi kusezinhlelweni zokukhiqiza amandla omoya, ezinhlelweni zokukhiqiza amandla e-photovoltaic noma ezinhlelweni zezimoto ezintsha zamandla, ukuthembeka okuphezulu nokuphila isikhathi eside kuyadingeka, ngakho-ke ukukhetha kwawo kubaluleke kakhulu.
Ingxenye.02 Isingeniso sikaUchungechunge lwe-MDP lwe-YMIN DC-Link Film Capacitor
Ama-capacitor efilimu e-DC-Link ochungechunge lwe-MDP e-YMIN adlala indima ebalulekile emkhakheni wamandla amasha, ikakhulukazi ekukhiqizeni amandla omoya, ekukhiqizeni amandla e-photovoltaic kanye nezinhlelo zezimoto ezintsha zamandla. Asebenza ngokuqina ngaphansi kwezimo zomthwalo ophezulu ngokuthembeka okuphezulu kanye nokuphila isikhathi eside.
Indima yochungechunge lwe-MDP emikhakheni ehlukahlukene yohlelo lokusebenza
Ingxenye.03 Izinzuzo zochungechunge lwe-MDP njenge-DC-Link capacitors
Uma kuqhathaniswa nama-capacitor e-electrolytic e-aluminium yendabuko,Uchungechunge lwe-MDP lwe-YMINAma-capacitor efilimu asebenza kangcono maqondana nokumelana ne-voltage, ukumelana ne-ripple, i-ESR ephansi, njll. Athuthukisa ukusebenza kahle kwesistimu, anciphisa ukulahleka kwamandla, athuthukisa ukuzinza, futhi afaneleka kakhulu ukusetshenziswa ezinhlelweni ezintsha zamandla.
Ingxenye.04 Isifinyezo
Ezisetshenzisweni zamandla amasha kanye nezimoto ezintsha zamandla, ama-capacitor e-DC-Link ayizingxenye ezibalulekile, ikakhulukazi ezinhlelweni ze-inverter, lapho ukushintshashintsha kwamandla kagesi okushelelayo kanye nama-voltage okushaya kwenhliziyo okumunca kubalulekile ekuthuthukiseni ukuthembeka kohlelo kanye nokuphila kwalo.
Ama-capacitor efilimu e-DC-Link ochungechungeni lwe-YMIN MDP ayisinqumo esifanele emkhakheni omusha wamandla ngenxa ye-voltage yawo ephezulu yokumelana, impilo ende, kanye ne-ESR ephansi. Uma kuqhathaniswa nama-capacitor e-aluminium electrolytic endabuko, uchungechunge lwe-MDP lunokuqina kwesistimu okuqinile futhi luyingxenye ebalulekile yokuthuthukisa ukusebenza kahle kwezinhlelo zamandla amasha nokwandisa impilo yemishini.
