Kuzama Kwambiri pa Ukadaulo | Kodi Ma DC-Link Film Capacitors Angathetse Bwanji Mavuto a Kuwonjezeka kwa Voltage ndi Kudalirika mu Mapulatifomu a Magetsi a 800V?

Chiyambi

Pamene nsanja za 800V zamagetsi amphamvu zikukhala zodziwika bwino m'magalimoto atsopano amphamvu, ma inverter amagetsi akuyika zofunikira kwambiri pa makhalidwe apamwamba a ma capacitor a DC-Link. Ma capacitor a aluminiyamu achikhalidwe, omwe amachepetsedwa ndi ESR yawo yayikulu komanso mayankho awo afupipafupi, amatha kukwera kwambiri kwa magetsi, zomwe zimalepheretsa magwiridwe antchito a makina ndikulepheretsa magwiridwe antchito onse a zida za SiC.

- Kusanthula Kwaukadaulo kwa Root Cause – Chifukwa cha zinthu zawo ndi kapangidwe kake, ma capacitor a aluminiyamu nthawi zambiri amakhala ndi ESR yapamwamba komanso ma frequency otsika odziyimira pawokha (nthawi zambiri pafupifupi 4kHz yokha). Pansi pa ntchito zosinthira ma frequency apamwamba, kuthekera kwawo kuyamwa mphamvu ya ripple yamagetsi apamwamba sikukwanira, zomwe zimapangitsa kusinthasintha kwa magetsi a basi mosavuta, zomwe zimakhudza kukhazikika kwa makina ndi moyo wa chipangizo chamagetsi. – YMIN Solutions and Process Advantages –Mndandanda wa MDP wa YMINMa capacitor a filimu amagwiritsa ntchito zinthu zopangidwa ndi polypropylene komanso njira yatsopano yozungulira kuti akwaniritse kusintha kwa magwiridwe antchito awa: ESR imachepetsedwa kufika pamlingo wa milliohm, zomwe zimachepetsa kwambiri kutayika kwa switching; ma frequency a resonant amawonjezeka kufika pa makumi a kHz, zomwe zimagwirizana mokwanira ndi zofunikira pakugwiritsa ntchito ma SiC/MOSFET; ndipo zabwino zake zimaphatikizapo magetsi amphamvu, mphamvu yotsika yotuluka, komanso moyo wautali, zomwe zimapangitsa kuti zikhale zoyenera kwambiri malo ogwirira ntchito amphamvu komanso amphamvu.

Zochitika Zogwiritsira Ntchito ndi Ma Model Ovomerezeka -

Chitsanzo Chofala Chogwiritsira Ntchito: Pulatifomu yayikulu yamagetsi ya 800V ya wopanga magalimoto imagwiritsa ntchito ma capacitor asanu ndi atatu a MDP-800V-15μF mu DC-Link circuit ya main drive inverter, ndikulowa m'malo mwa ma capacitor 22 a aluminiyamu a 450V a aluminium electrolytic a yankho loyambirira. Izi zimachepetsa dera la PCB ndi kupitirira 50%, zimachepetsa kuchuluka kwa magetsi a basi ndi 40%, ndikukweza magwiridwe antchito a dongosolo ndi pafupifupi 1.5%. - Ma Model Ovomerezeka -

Mapeto
Mndandanda wa YMIN MDP si capacitor yogwira ntchito kwambiri yokha komanso ndi wowongolera mphamvu zamagetsi m'makina amphamvu kwambiri komanso okhala ndi ma frequency ambiri. Ungathandize mainjiniya kuthana ndi mavuto a kapangidwe kake ndikukweza magwiridwe antchito ndi kudalirika kwa makina.
