Ibidukikije byimodoka nimwe mubidukikije bikabije bya elegitoroniki. Uyu munsiAmashanyaraziibishushanyo byiyongera hamwe na elegitoroniki yoroheje, harimo kugenzura ibikoresho bya elegitoronike, infotainment, sensing, paki ya batiri, gucunga bateri,aho amashanyarazi, hamwe na charger. Usibye ubushyuhe, ihererekanyabubasha rya voltage, hamwe n’ubuvanganzo bwa electronique (EMI) mu bidukikije by’imodoka, charger yo mu ndege igomba guhuza na gride ya AC, bisaba gukingirwa n’imivurungano ya AC kugirango ikore neza.
Abakora ibice byumunsi batanga ibikoresho byinshi byo kurinda imiyoboro ya elegitoroniki. Bitewe no guhuza gride, kurinda-charger kurinda kurinda voltage ukoresheje ibice byihariye ni ngombwa.
Igisubizo kidasanzwe gihuza SIDACtor na Varistor (SMD cyangwa THT), igera kuri voltage ntoya ya clamping munsi yumuvuduko mwinshi. SIDACtor + MOV ikomatanya ituma abajenjeri batwara ibinyabiziga bahitamo neza guhitamo, bityo rero, ikiguzi cyingufu za semiconductor mugushushanya. Ibi bice birakenewe kugirango uhindure voltage ya AC mumashanyarazi ya DC kugirango yishyure ikinyabizigakwishyuza bateri.
Igicapo 1. Igishushanyo mbonera cyo Kwishyuza
Ku NamaAmashanyarazi(OBC) ifite ibyago mugiheKwishyuzakubera guhura nibintu birenze urugero bishobora kugaragara kuri gride ya power. Igishushanyo kigomba kurinda ingufu za semiconductor zitwara amashanyarazi arenze urugero kuko voltage iri hejuru yimipaka ntarengwa ishobora kubangiza. Kugirango wongere ubwizerwe bwa EV hamwe nubuzima bwe bwose, injeniyeri agomba gukemura ibibazo byiyongera byubu kandi bigabanya ingufu za clamping nini mubishushanyo byabo.
Urugero rwamasoko ya voltage yinzibacyuho irimo ibi bikurikira:
Guhindura imitwaro ya capacitive
Guhindura sisitemu ya voltage ntoya hamwe na sisitemu ya resonant
Imirongo migufi ituruka kubwubatsi, impanuka zo mumuhanda, cyangwa umuyaga
Gukurura fus no kurinda birenze urugero.
Igicapo 2. Basabwe kuzenguruka kubitandukanye kandi Bisanzwe Mode Yinzibacyuho Yumuzunguruko Wumuzingi Ukoresheje MOV na GDT.
MOV ya 20mm ikunzwe kugirango irusheho kwizerwa no kurindwa. 20mm MOV ikora pulses 45 za 6kV / 3kA zikoresha amashanyarazi, zikaba zikomeye cyane kuruta 14mm MOV. Disiki ya 14mm irashobora gukora gusa 14 hejuru yubuzima bwayo.
Igicapo 3. Gufata imikorere ya lnfuse Ntoya V14P385AUTO MOV Munsi ya 2kV na 4kV. Umuvuduko wa Clamping urenga 1000V.
Urugero rwo guhitamo
Urwego rwa 1—120VAC, umuzunguruko w'icyiciro kimwe: Ubushyuhe bwibidukikije buteganijwe ni 100 ° C.
Kumenya byinshi kubyerekeye gukoresha SIDACt cyangwa Kurinda Thyristors muriibinyabiziga by'amashanyarazi.
