Kunyura Kwakadzika Kwehunyanzvi | DC-Link Film Capacitors Inogona Sei Kugadzirisa Matambudziko Ekuwedzera Kwemagetsi uye Kuvimbika Mumapuratifomu Emagetsi e800V?

Nhanganyaya

Sezvo mapuratifomu e800V ane voltage yepamusoro achinyanya kushandiswa mumotokari itsva dzemagetsi, ma inverter emagetsi ari kuwedzera kudiwa kwemagetsi ane DC-Link capacitors. Ma capacitor emagetsi ealuminium echinyakare, anoganhurirwa neESR yavo yakakwira uye mhinduro yefrequency, anowanzo sangana ne voltage surges, zvichideredza kushanda zvakanaka kwesystem uye zvichikanganisa kushanda kwese kweSiC devices.

Mhinduro dzeYMIN Film Capacitor

- Kuongororwa Kwehunyanzvi hweRoot Cause – Nekuda kwezvinhu zvavo uye hunhu hwemaumbirwo avo, macapacitor ealuminium electrolytic anowanzova neESR yakakwira uye frequency yakaderera yekuzvitenderedza (kazhinji inosvika 4kHz chete). Pasi pekushanda kwekushandura kwefrequency yakakwira, kugona kwavo kupinza frequency ripple current hakukwani, zvichikonzera kushanduka kwevoltage yebhazi, izvo zvinokanganisa kugadzikana kwesystem uye hupenyu hwechishandiso chemagetsi. – YMIN Solutions uye Mabhenefiti eMaitiro –Nhevedzano yeMDP yeYMINMa capacitor efirimu anoshandisa simbi yakagadzirwa ne polypropylene firimu uye nzira itsva yekumonera kuti awane zvinotevera zvinovandudza mashandiro: ESR inoderedzwa kusvika pachiyero che milliohm, zvichideredza zvakanyanya kurasikirwa kwe switching; frequency ye resonant inowedzerwa kusvika kumakumi e kHz, zvichienderana zvizere nezvinodiwa zve high-frequency application zveSiC/MOSFETs; uye zvakanakira zvavo zvinosanganisira high-standing voltage, low leakage current, uye hupenyu hurefu, zvichiita kuti zvive zvakakodzera munzvimbo dzekushanda dzine high-voltage, high-frequency.

Maitiro Ekushandisa uye Mamodheru Anokurudzirwa -

Nyaya Yakajairika Yekushandisa: Chikuva chikuru chemotokari che800V chinoshandisa ma capacitor masere eMDP-800V-15μF muDC-Link circuit ye ​​main drive inverter, zvichibudirira kutsiva ma capacitor e22 450V aruminiyamu electrolytic emhinduro yekutanga. Izvi zvinoderedza nzvimbo yePCB neanopfuura 50%, zvinoderedza peak yevoltage yebhazi ne40%, uye zvinovandudza kushanda zvakanaka kwesystem neinenge 1.5%. - MaModheru Anokurudzirwa -

Mhedziso
YMIN MDP series haisi capacitor inoshanda zvakanyanya chete asiwo inodzora voltage mumagetsi ane voltage yakawanda uye mafrequency akawanda. Inogona kubatsira mainjiniya kugadzirisa matambudziko ekugadzira uye kuvandudza mashandiro ehurongwa nekuvimbika kwahwo.
