Mune nyowani simba photovoltaic masisitimu, inoshandura magetsi ekuchengetedza (PCS) ndiyo musimboti hubhu yekushandurwa kwakanaka kweiyo photovoltaic DC simba kuita grid AC simba. YMIN film capacitors, ine high voltage resistance, kurasikirwa kwakaderera, uye hupenyu hurefu, zvinhu zvakakosha zvekusimudzira kushanda kwe photovoltaic PCS inverters, zvichibatsira photovoltaic magetsi emagetsi kuwana simba rinoshandura simba uye kubuda kwakagadzikana. Mabasa avo epakati uye mabhenefiti ehunyanzvi ndeaya anotevera:
1. "Voltage Stabilization Shield" yeDC-Link
Munguva ye AC-DC yekushandura maitiro mu photovoltaic PCS inverters, iyo DC bhazi (DC-Link) inozviisa pasi pepamusoro pulse currents uye voltage spikes. YMIN mafirimu capacitors anopa aya mabhenefiti ne:
• High-Voltage Surge Absorption: Kutarisana nepamusoro-soro ye500V kusvika ku1500V (customizable), inotora nguva pfupi yemagetsi spikes inogadzirwa neIGBT / SiC switches, kuchengetedza zvigadzirwa zvemagetsi kubva pakuparara kwenjodzi.
• Low ESR Current Smoothing: Low ESR (1/10 iyo yechinyakare aluminium electrolytic capacitors) inonyatsotora high-frequency ripple current paDC-Link, kuderedza kurasikirwa kwesimba nekuvandudza simba rekushandura simba.
• High-Capacity Energy Storage Buffer: Kuwanda kwehuwandu hwehuwandu hunobvumira kukurumidza kuchaja uye kuburitsa panguva yekushanduka kwemagetsi egridi, kuchengetedza DC bhazi voltage kugadzikana uye kuve nechokwadi chekushanda kwePCS inoenderera.
2. Dual Kudzivirirwa kweHigh Voltage Kutsungirira uye Temperature Kugadzikana
PV zviteshi zvemagetsi zvinowanzotarisana nenzvimbo dzakaoma senge tembiricha yepamusoro uye hunyoro hwepamusoro. YMIN mafirimu capacitors anosangana nematambudziko aya kuburikidza nemagadzirirwo matsva:
• Stable Operation pamusoro Wide Temperature Range: Kushanda tembiricha inovhara -40 ° C kusvika 105 ° C, ine capacitance degradation mwero weisingasviki 5% munzvimbo dzepamusoro-tembiricha, kudzivirira system downtime nekuda kwekushanduka kwekushisa.
• Ripple Current Capacity: Ripple current handling capability inopfuura ka10 iyo yechinyakare electrolytic capacitors, inonyatso kusefa harmonic ruzha pakubuda kwePV nekuona kuti grid-yakabatana simba remagetsi rinosangana nemitemo yenyika.
• Upenyu Hwakareba uye Kuchengetedza-Kusununguka: Nehupenyu hunosvika maawa 100,000, inopfuura kudarika maawa 30,000-50,000 ealuminium electrolytic capacitors, izvi zvinoderedza kushanda uye kuchengetedza mari yemagetsi e photovoltaic.
3. Synergy neSiC / IGBT Devices
Sezvo mafotovoltaic masisitimu anoshanduka akananga kune akakwira voltages (1500V zvivakwa zvichive zvakanyanya), YMIN yakaonda-firimu capacitors inopindirana zvakanyanya neinotevera-chizvarwa simba semiconductors:
• High-Frequency Switching Support: Iyo yakaderera-inductance dhizaini inoenderana nepamusoro-frequency maitiro eSiC MOSFETs (kuchinja frequency> 20kHz), kuderedza nhamba yezvikamu zvepasi uye kubatsira kune miniaturization yePCS masisitimu (a 40kW system inoda chete 8 capacitors, ichienzaniswa ne22 yesilicon-based solutions).
• Yakanatsiridza dv/dt Kumira: Kuwedzeredzwa kuchinjika kune kushanduka kwemagetsi, kudzivirira voltage oscillations kunokonzerwa nekunyanyisa kushandura kumhanya muSiC zvishandiso.
4. System-Level Value: Improvement Energy Efficiency uye Cost Optimization
• Kubudirira Kwakavandudzwa: Iyo yakaderera ESR dhizaini inoderedza kupisa kurasikirwa, inosimudzira yakazara PCS kunyatsoshanda uye zvakanyanya kuwedzera gore negore kugadzirwa kwesimba.
• Space Saving: High power density design (40% madiki pane echinyakare capacitor) inotsigira compact PCS michina marongerwo uye inoderedza kuisa mari.
Mhedziso
YMIN firimu capacitor, ine mabhenefiti ayo epamusoro ekushivirira kwemagetsi, kukwira kwakadzika tembiricha, uye zero kugadzirisa, zvakabatanidzwa zvakanyanya muzvinhu zvakakosha zve photovoltaic PCS inverters, kusanganisira DC-Link buffering, IGBT dziviriro, uye grid harmonic kusefa. Vanoshanda se "muchengeti asingaoneki" wekushanda uye kugadzikana kwekushanda mumagetsi e photovoltaic. Tekinoroji yavo haingofambisi photovoltaic simba rekuchengetedza masisitimu kune "yemahara-yemahara mukati mehupenyu hwavo hwose," asi zvakare inobatsira iyo itsva indasitiri yesimba kumhanyisa kubudirira kwegridi parity uye zero-kabhoni shanduko.
