Polokelo ea matla e bolela mokhoa oa ho boloka matla ka mochine kapa sesebelisoa le ho a lokolla ha a hlokahala nakong e tlang. Litsamaiso tsa polokelo ea matla li bapala karolo ea bohlokoa lits'ebetsong tse ncha tsa motlakase. Li-inverters tsa polokelo ea matla li bapala karolo ea phetolo ea matla, taolo le puisano tsamaisong, le ho tjhaja ka mahlakoreng a mabeli le ho lahla ho ntlafatsa ts'ebeliso ea matla a matla.
Li-converter tsa polokelo ea matla hangata li na le pheletso ea ho kenya, pheletso ea tlhahiso le sistimi ea taolo. Ha o sebelisana le marang-rang a matla, li-capacitor tse nang le matla a maholo, ho hanyetsa litšisinyeho tse kholo tsa hajoale, le ESR e tlase li sebelisoa haholo ho etsa mesebetsi e kang ho tsitsisa ha motlakase le ho sefa, ho boloka matla le ho lokolloa ho fihlela li-pulsations tsa DC, ka hona, ho eketsa ts'ebetso ea converter le botsitso ba ts'ebetso ea sistimi ea polokelo ea matla, le ho sireletsa sesebelisoa ha se kopana le maemo a sa tloaelehang a ho sebetsa.
1. High capacitance segokanyipalo
Li-capacitor tsa lifilimi tsa MDPna le litšobotsi tsa high capacitance density, e leng ea bohlokoa bakeng sa PCS ho boloka matla a motlakase a tsitsitseng nakong ea phetoho ea matla. Mejalong e joalo ka li-motor, tse tobane le tlhokahalo ea matla, li-capacitor tsa lifilimi li fana ka matšeliso a matla a sebetsang, ho tsitsisa motlakase, le ho ntlafatsa ts'ebetso ea li-motor, ka hona, ho ntlafatsa ts'ebetso ea matla le botsitso ba lits'ebetso tsa polokelo ea matla.
2. Ho tšepahala ho phahameng le bophelo bo bolelele
Ha ho bapisoa le li-capacitor tse tloaelehileng tsa aluminium electrolytic capacitor, li-capacitor tsa filimi tsa YMIN li na le bophelo bo bolelele ba ts'ebeletso le ts'epahalo e phahameng. Ha ho bonolo ho tsofala, e na le khanyetso e ntle ea mocheso o phahameng, 'me e ka sebetsa ka mokhoa o tsitsitseng nako e telele tlas'a maemo a thata a tikoloho. Sena ke sa bohlokoa haholo bakeng sa ts'ebetso e tsitsitseng ea PCS maemong a fapaneng a rarahaneng.
3. Khanyetso ea hona joale ea Ripple
Li-capacitor tsa lifilimi tsa MDP li ka sebelisoa bakeng sa ho sefa, ho fokotsa mefuta ea maqhubu a matšoao kapa ho fokotsa lerata la matšoao. Ho PCS, e thusa ho fokotsa lerata la maqhubu a phahameng le ripple e hlahisoang nakong ea phetoho ea matla, ho ntlafatsa boleng ba matla, hape e ka sebelisoa e le sesebelisoa sa ho kopanya ho fetisetsa lipontšo tse fapaneng ho lipotoloho tse lumellanang, ka hona ho hlokomela tšebelisano ea data le phetiso ea matšoao. Ntle le moo, e ka sebetsa joalo ka potoloho ea buffer, e monya le ho hatella tšitiso ea nakoana le tšusumetso ea hona joale potolohong, ho sireletsa likarolo tse ling tsa elektroniki ho senya.
02 Khetho e khothaletsoang ea capacitor ea lifilimi
Lihlahisoa tse tloaelehileng tsa phini, ESR e tlase, lihlahisoa tsa 105 ℃ 100000H
03 Kakaretso
Li-capacitor tsa lifilimi tsa YMIN MDPna le melemo ea matla a mangata a mangata, ho hanyetsa hona joale, ho tšepahala ho phahameng, le bophelo bo bolelele. Li thusa li-converter tsa PCS ho fetolela AC le DC le ho phethela ts'ebetso ea phallo ea matla a mabeli. Ka nako e ts'oanang, ba ka fokotsa litlhōrō le ho tlatsa liphula ho ntlafatsa ts'ebeliso ea matla a matla, ho thibela ho imeloa le ho netefatsa tšireletso ea tsamaiso. Li bohlokoa haholo ho ntlafatsa polokeho, botsitso le katleho ea litsamaiso tsa polokelo ea matla. Ka tsoelo-pele e potlakileng ea mekhoa ea ho boloka matla tšimong ea matla a macha, litebello tsa kopo ea li-capacitor tsa lifilimi li tla ba tse pharaletseng.
