Solar photovoltaic power generation tla phetha karolo ea bohlokoa tshebedisong ya matla a lefatše nakong e tlang e haufi, eseng feela ho nka sebaka sa mehloli e meng e tloaelehileng ea matla, empa hape le ho ba mohloli o ka sehloohong oa phepelo ea matla a lefats'e.
Li-inverters tsa photovoltaic ke li-inverters tse fetolang matla a motlakase a DC a hlahisoang ke liphanele tsa letsatsi tsa photovoltaic (PV) hore e be lisebelisoa tsa maqhubu a feto-fetohang (AC), tse ka khutlisetsoang tsamaisong ea phetisetso ea khoebo kapa ea sebelisoa ho off-grid system.Kaha li-inverters hangata li sebelisoa maemong a kantle mme li hloka ts'ebetso e ts'eptjoang ea nako e telele le tlhokomelo e fokolang, basebelisi ba ho qetela le baqapi ba na le litlhoko tse thata haholo tsa boleng le ts'epahalo bakeng sa likarolo tse sebelisoang lisebelisoa tsena.E le mofani le ts'ehetso ea ts'ebetso ea ho fetola matla, li-capacitor tsa filimi li phetha karolo ea bohlokoa likarolong tsohle tsa li-inverters tsa photovoltaic.Haeba li sa khethoe hantle, li tla ba le phello e bolaeang botsitso le bophelo bohle ba thepa.
Bakeng sa ts'ebeliso ea potoloho ea inverter, ka kopo sheba mohlala oa ts'ebeliso setšoantšong se ka tlase:
Karolo ea DC-link capacitor:
1) Potolohong ea inverter, motlakase o hlahisoang oa rectifier o boreleli haholo ebile o tlhotliloeng;
2) Kenya matla a phahameng a amplitude a kopiloeng ke inverter ho tsoa ho "DC-Link", e thibele ho hlahisa matla a phahameng a amplitude pulsating voltage ho "DC-Link", 'me u boloke ho feto-fetoha ha motlakase ka beseng ea DC. sebaka se amohelehang sa marang-rang;
3) Thibela ho overshoot ha voltage le overvoltage ea nakoana ea "DC-Link" ho ama IGBT.
Ka hona, litlhoko tsa capacitors:
1) Etsa bonnete ba ho mamella voltage e lekaneng
2) Bokhoni bo lekaneng
3) Bokhoni bo lekaneng ba hona joale, ESR e tlase kamoo ho ka khonehang
4) E hloka litšobotsi tse ntle tsa maqhubu, ESL e tlase kamoo ho ka khonehang
5) Khotsofatsa mocheso o phahameng oa kantle le boemo ba kopo ea mongobo o phahameng
Wuxi CRE New Energy Technology Co., Ltd esale e tsepamisitse maikutlo ts'ebelisong ea li-capacitor tsa lifilimi ho lisebelisoa tsa elektroniki ka nako e telele.E shebane le boemo bo boima ba ts'ebeliso ea li-inverters tsa photovoltaic, tse thehiloeng ho theknoloji ea filimi e hanyetsanang e phahameng ea CRE's DC, e amohela tahlehelo e tlase, e sa keneleng mocheso o phahameng oa mocheso oa Polypropylene Dielectric e qapile le ho hlahisa letoto la li-capacitor tsa lifilimi tse nang le mocheso o phahameng le mongobo o phahameng. ho hanyetsa, ESR e tlaase (mofuto o tlaase oa mocheso), ho tšepahala ho phahameng le bophelo bo bolelele.
Har'a tsona, litšobotsi tsa ts'ebetso ea DMJ-PS DC capacitor ea libese ke tse latelang:
Boholo ba mocheso o sebetsang: 105 °C (mokotla oa polasetiki)
Sehlopha sa boemo ba leholimo (IEC 60068-1:2013): 40/105/56
