Q: Yiziphi izidingo zesilinganiso se-voltage esiyinhloko sama-capacitor kusekethe ye-DC-Link yesikhulumi esingu-800V?
A: Ukuqinisekisa isidingo sesilinganiso se-voltage kuyisinyathelo sokuqala ekukhetheni, kodwa kuyadingeka ukucacisa uhlobo oluthile lwe-test waveform kanye nenani lemiphumela yokukhuphuka. Ekuhlolweni kwe-DV, kunconywa ukubhekisela ku-ISO 16750-2 noma amazinga alinganayo, kusetshenziswa ama-pulse omthwalo ohambayo ajikelezayo (njenge-load dumps) ukuqinisekisa isilinganiso se-voltage se-capacitor kanye nokuqina kwe-capacitance ngemuva kwamakhulu ama-pulse anjalo, okuqinisekisa ukusebenza kahle kwe-margin yayo yokuklama.
Uhlobo Lombuzo: Amandla Okugobhoza
Q: Ezindaweni zokushintshashintsha imvamisa ephezulu, ama-capacitor kudingeka amelane nemisinga ye-ripple ephezulu kakhulu. Yibuphi ubuchwepheshe obusetshenziswa uchungechunge lwe-CW3H ukuthuthukisa ukubekezelelana kwamanje kwe-ripple? Lusebenza kanjani ngokusebenza?
A: Kufezwe ngokusungula izinto ezintsha—kusetshenziswa i-electrolyte entsha ephansi yokulahlekelwa, kunciphisa ngempumelelo ukumelana kochungechunge olulinganayo (ESR), ngaleyo ndlela kwandisa ukubekezelelana kwamanje kwe-ripple kube izikhathi ezingu-1.3 kunenani elilinganiselwe. Ukuqinisekiswa kwedatha yelabhorethri kukhombisa ukuthi ngezikhathi ezingu-1.3 kwamanje we-ripple olinganiselwe, ukukhuphuka kwezinga lokushisa eliyinhloko kwalolu chungechunge lwama-capacitor kuzinzile ngaphandle kokuwohloka kokusebenza. Ngokwezincazelo ezijwayelekile, imodeli engu-450V 330μF ifinyelela ugesi we-ripple ongu-1.94mA ku-120kHz, kanti imodeli engu-450V 560μF ifinyelela ku-2.1mA, ihlangabezana nezidingo zokubekezelelana kwe-ripple zezimo zokushintsha kwe-high-frequency. Amandla e-ripple ayisisekelo sokuklama kwe-high-frequency futhi adinga idatha yobunjiniyela eqinisekisiwe. Kubalulekile ukuthola isilinganiso samanje we-ripple (I rms ) kanye ne-derating current yemodeli eqondiwe kumhlinzeki ekushiseni okuphezulu kakhulu kokusebenza (isb., 105°C) kanye nemvamisa yokushintsha yangempela (isb., 100kHz). Ngesikhathi sokuklama, i-ripple yokusebenza yangempela kufanele ibe ngaphansi ngo-70%-80% kunalesi silinganiso ukulawula ukwenyuka kwezinga lokushisa nokwandisa isikhathi sokuphila.
Uhlobo Lombuzo: Ibhalansi Yosayizi Nomthamo
U: Uchungechunge lwe-CW3H lufinyelela kanjani ibhalansi phakathi "kosayizi omncane kanye nomthamo ophezulu" lapho isikhala semodyuli silinganiselwe? Yiziphi izinsizakalo zenqubo ekukhiqizeni?
A: Ukwehla kwevolumu kusho ukwanda kokushisa okungenzeka kube khona ngevolumu ngayinye. Ngesikhathi sokuhlelwa, ukulingisa ukushisa kuyadingeka ukuze kwenziwe ngcono ukuhamba komoya noma izindlela zokusabalalisa ukushisa ezizungeze i-capacitor. Ngesikhathi esifanayo, ukwakheka kwendawo yokulungisa ama-capacitor amancane kudinga ukunemba okukhulu ukuvimbela ukucindezeleka okwengeziwe ngesikhathi sokudlidliza. Lokhu kufezwa ngokusungula inqubo ohlangothini lokuklama—kusetshenziswa izinqubo ezikhethekile zokubopha nokubopha ukuze kuthuthukiswe isakhiwo sangaphakathi, kufezwe “umthamo ophezulu ngevolumu efanayo” noma “cishe ukwehla kwevolumu okungu-20% kumininingwane efanayo.” Ngasohlangothini lokukhiqiza, le nqubo eyenziwe ngokwezifiso iphakathi; isibonelo, imininingwane engu-450V 330μF idinga u-25*50mm kuphela, kanti imininingwane engu-450V 560μF ingu-30*50mm, okunciphisa kakhulu ivolumu uma kuqhathaniswa nemikhiqizo yendabuko yemininingwane efanayo, okuvumelana nendawo yokufaka elinganiselwe yemodyuli.
Uhlobo Lombuzo: Izinkomba Zesikhathi Sokuphila
Q: Ingabe isikhathi sokuphila samahora angu-3000 ku-105℃ sanele ukusetshenziswa kwezimoto zangempela?
