Intshayelelo
Njengoko amaqonga e-800V aphezulu e-voltage eqala ukusetyenziswa kwizithuthi ezintsha zamandla, ii-inverters zombane zibeka iimfuno eziphezulu kwiimpawu eziphezulu ze-DC-Link capacitors. Ii-capacitors ze-aluminium electrolytic zemveli, ezithintelwe yi-ESR yazo ephezulu kunye nempendulo ye-frequency, zinomngcipheko wokunyuka kwamandla e-voltage, okunciphisa ukusebenza kakuhle kwenkqubo kwaye kuthintele ukusebenza ngokupheleleyo kwezixhobo ze-SiC.

Izisombululo ze-YMIN Film Capacitor
- Uhlalutyo loBugcisa lweNtsonamba – Ngenxa yezinto ezisetyenziswayo kunye neempawu zesakhiwo, ii-capacitor ze-aluminium electrolytic zihlala zine-ESR ephezulu kunye ne-frequency ephantsi yokuziphendulela (ngesiqhelo malunga ne-4kHz kuphela). Phantsi kwemisebenzi yokutshintsha i-frequency ephezulu, amandla azo okufunxa i-ripple current ephezulu awanelanga, nto leyo ebangela ukuguquguquka kwe-voltage yebhasi, nto leyo echaphazela uzinzo lwenkqubo kunye nobomi besixhobo samandla. – Izisombululo ze-YMIN kunye neeNzuzo zeNkqubo –Uthotho lwe-MDP lwe-YMINIi-capacitor zefilimu zisebenzisa izixhobo zefilimu ze-polypropylene ezenziwe ngesinyithi kunye nenkqubo entsha yokujika ukuze kufezekiswe uphuculo lokusebenza olulandelayo: I-ESR incitshisiwe ukuya kwinqanaba le-milliohm, nto leyo enciphisa kakhulu ilahleko zokutshintsha; i-frequency ye-resonant inyuswa ukuya kwi-tens ye-kHz, ivumelana ngokupheleleyo neemfuno zesicelo se-high-frequency ze-SiC/MOSFETs; kwaye izibonelelo zazo ziquka i-voltage ephezulu yokumelana, i-low leakage current, kunye nobomi obude, nto leyo eyenza ukuba zifaneleke ngakumbi kwiindawo zokusebenza ze-high-voltage, high-frequency.

Imeko eqhelekileyo yokusetyenziswa: Iqonga lombane le-800V lomenzi wemoto omkhulu lisebenzisa ii-capacitor ezisibhozo ze-MDP-800V-15μF kwisekethe ye-DC-Link ye-inverter ephambili ye-drive, itshintsha ngempumelelo ii-capacitor ze-aluminium electrolytic ezingama-22 450V zesisombululo sokuqala. Oku kunciphisa indawo ye-PCB ngaphezulu kwe-50%, kunciphisa i-voltage yebhasi nge-40%, kwaye kuphucula ukusebenza kakuhle kwenkqubo malunga ne-1.5%. - Iimodeli ezicetyiswayo -
Isiphelo
Uthotho lwe-YMIN MDP alupheleli nje ekubeni yi-capacitor esebenza kakhulu kodwa lukwangumlawuli we-voltage ophambili kwiinkqubo ze-voltage ephezulu ne-frequency ephezulu. Lunokunceda iinjineli ukuba zijongane nemingeni yoyilo kwaye ziphucule ngokupheleleyo ukusebenza kwenkqubo kunye nokuthembeka kwayo.
