Daim Ntawv Thov Scenario 2: Lub Zog Cia Hloov (PCS) - Bidirectional EMI Lim rau Them thiab Tshem Tawm
Lub zog cia converters tso cai rau lub zog hloov dua siab tshiab ntawm lub roj teeb thiab daim phiaj. Nyob rau hauv ob qho tib si them thiab tso tawm hom, tiam mechanisms thiab propagation paths ntawm hom-hom suab nrov sib txawv, imposing bidirectional filtering yuav tsum tau rau lub hom-hom choke.
Cov Kev Sib Tw Core
- Raws li kev ua haujlwm bidirectional, hom suab nrov nrov zaus bands thiab amplitudes txawv
- Nyob rau hauv high-tam sim no tus nqi / tso tawm tej yam kev mob, lub choke yuav tsum tsis txhob poob qis thiab tsis kub nce
- Lub zog cia tshuab muaj cov kev xav tau siab heev rau kev ntseeg tau ntev
Kev tsim nyog ntawm SQ3324 Series
- Tsawg DCR (15mΩ) txo lub zog poob thaum them thiab tawm
- Tsawg kub nce tsim (<55°C) ensures long-term stable operation
- Ib-theem winding yuav txo tau txoj kev tsis txaus ntseeg, txhim kho kev ua haujlwm siab-hom kev txwv
- Flat hlau winding txhim kho qhov chaw siv, yoog raws li kev cog lus ntawm lub zog cia PCS
Daim Ntawv Thov Scenario 3: EV Charging Chaw - EMI Ua Raws Cai rau Kev Them Nyiaj Tam Sim No
Lub hwj chim theem ntawm DC ceev them chaw nres tsheb rau lub tsheb fais fab yog li ntawm 60kW mus rau ntau tshaj 350kW, nrog cov zis tam sim no mus txog pua pua amperes. AC-DC thiab DC-DC hloov pauv theem hauv qhov chaw them nqi tsim cov suab nrov nrov, uas yuav tsum tau ua kom zoo los ntawm kev sib koom ua ke kom ntseeg tau tias cov cuab yeej dhau EMI daim ntawv pov thawj.
Cov Kev Sib Tw Core
