Ukucwila Okujulile Kobuchwepheshe | Ama-DC-Link Film Capacitors Angabhekana Kanjani Nezinselele Zokwanda Kwe-Voltage Nokuthembeka Kumapulatifomu E-Electric Drive angu-800V?

Isingeniso

Njengoba amapulatifomu aphezulu e-voltage angu-800V eba yinto evamile ezimotweni ezintsha zamandla, ama-inverter kagesi abeka izidingo eziphakeme ezicini zemvamisa ephezulu yama-capacitor e-DC-Link. Ama-capacitor e-aluminium electrolytic endabuko, anqunyelwe yi-ESR yawo ephezulu kanye nokuphendula kwemvamisa, athambekele ekukhuphukeni kwamandla kagesi, anciphise ukusebenza kahle kwesistimu futhi avimbele ukusebenza okugcwele kwamadivayisi e-SiC.

Izixazululo ze-YMIN Film Capacitor

- Ukuhlaziywa Kobuchwepheshe Bezimbangela Eziyinhloko – Ngenxa yezinto ezibonakalayo kanye nezici zesakhiwo sazo, ama-capacitor e-aluminium electrolytic ngokuvamile ane-ESR ephezulu kanye nemvamisa ephansi yokuziphendulela (ngokuvamile cishe i-4kHz kuphela). Ngaphansi kwemisebenzi yokushintsha imvamisa ephezulu, ikhono lawo lokumunca ugesi we-ripple ovame kakhulu alanele, okubangela ukushintshashintsha kwamandla kagesi ebhasi kalula, okuthinta ukuzinza kwesistimu kanye nokuphila kwedivayisi yamandla. – Izixazululo ze-YMIN kanye Nezinzuzo Zenqubo –Uchungechunge lwe-MDP lwe-YMINAma-capacitor efilimu asebenzisa izinto zefilimu ye-polypropylene ezenziwe ngensimbi kanye nenqubo entsha yokugoqa ukuze kufezwe ukuthuthukiswa kokusebenza okulandelayo: I-ESR yehliswa ibe yizinga le-milliohm, okunciphisa kakhulu ukulahlekelwa kokushintsha; imvamisa ye-resonant ikhushulwa ibe amashumi e-kHz, okuvumelana ngokugcwele nezidingo zohlelo lokusebenza lwemvamisa ephezulu yama-SiC/MOSFET; futhi izinzuzo zawo zifaka phakathi i-voltage ephezulu yokumelana, ugesi ophansi wokuvuza, kanye nokuphila isikhathi eside, okwenza zifaneleke kakhulu ezindaweni zokusebenza ze-voltage ephezulu, nemvamisa ephezulu.

Izimo Zokusebenza Namamodeli Anconyiwe -

Icala Lokusebenza Elijwayelekile: Ipulatifomu yokushayela kagesi engu-800V yomenzi wezimoto omkhulu isebenzisa ama-capacitor ayisishiyagalombili e-MDP-800V-15μF kusekethe ye-DC-Link ye-inverter eyinhloko yokushayela, ishintsha ngempumelelo ama-capacitor e-aluminium angu-22 450V e-aluminium electrolytic esixazululo sokuqala. Lokhu kunciphisa indawo ye-PCB ngaphezu kuka-50%, kunciphisa i-voltage yebhasi ngo-40%, futhi kuthuthukisa ukusebenza kahle kwesistimu cishe ngo-1.5%. - Amamodeli Anconyiwe -

Isiphetho
Uchungechunge lwe-YMIN MDP aluyona nje i-capacitor esebenza kahle kakhulu kodwa futhi luyisilawuli se-voltage esibalulekile ezinhlelweni ze-voltage ephezulu nemvamisa ephezulu. Lungasiza onjiniyela ukuthi babhekane nezinselele zokuklama ngokuyisisekelo futhi bathuthukise ngokuphelele ukusebenza kwesistimu nokuthembeka kwayo.
