Paunenge uchigadzira kana kuwedzera masisitimu anofambiswa nebhatiri, mubvunzo wakajairika unomuka: Mabhatiri maviri mapaketi ane voltage yakafanana angabatanidzwa munhevedzano here? Mhinduro pfupi ndeyekutiEhe, asi nechinodiwa chakakosha:iyo voltage inomira kugona kwedunhu rekudzivirirainofanira kunyatsoongororwa. Pazasi, isu tinotsanangura iyo tekinoroji ruzivo uye matanho ekuona kuti ive yakachengeteka uye yakavimbika kushanda.
Kunzwisisa Miganhu: Dziviriro Circuit Voltage Tolerance
Lithium bhatiri mapaketi anowanzo kuve akashongedzerwa neProtection Circuit Board (PCB) kudzivirira kuwandisa, kuburitsa zvakanyanya, uye mapfupi maseketi. Iyo yakakosha parameter yePCB iyi ndeyevoltage inomira chiyero cheMOSFETs yayo(magetsi emagetsi anodzora kuyerera kwezvino).
Muenzaniso Scenario:
Tora maviri 4-sero LiFePO4 bhatiri mapaketi semuenzaniso. Paki yega yega ine yakazara charge voltage ye14.6V (3.65V pasero). Kana yakabatana munhevedzano, yavo yakasanganiswa voltage inova29.2V. Iyo yakajairwa 12V bhatiri yekudzivirira PCB inowanzogadzirwa neMOSFETs akatemerwa35–40V. Mune ino kesi, iyo yakazara voltage (29.2V) inowira mukati meyakachengeteka renji, ichibvumira mabhatiri kuti ashande nemazvo munhevedzano.
Ngozi Yekupfuura Miganho:
Nekudaro, kana ukabatanidza mapaketi mana akadaro munhevedzano, iyo yakazara voltage inodarika 58.4V-kure kupfuura iyo 35-40V kushivirira kweyakajairwa PCBs. Izvi zvinogadzira njodzi yakavanzika:
Sayenzi Inokonzera Ngozi
Kana mabhatiri akabatanidzwa munhevedzano, iwo ma voltages anowedzera, asi maseketi ekudzivirira anoshanda akazvimirira. Mumamiriro ezvinhu akajairwa, iyo yakasanganiswa voltage inopa simba mutoro (semuenzaniso, 48V mudziyo) pasina nyaya. Zvisinei, kanarimwe bhatiri pack rinokonzera dziviriro(semuenzaniso, nekuda kwekuwandisa-kuburitsa kana kuwandisa), maMOSFET ayo anobvisa iyo paki kubva kudunhu.
Panguva ino, iyo yakazara voltage yemabhatiri asara munhevedzano inoiswa kune yakabviswa MOSFETs. Semuenzaniso, mune mana-pack setup, PCB yakabviswa yaizotarisana nepedyo58.4V-kupfuura chiyero chayo che35-40V. Iwo maMOSFET anogona kuzokundikana nekuda kwekuparara kwemagetsi, kudzima zvachose dunhu redziviriro uye kusiya bhatiri panjodzi yenjodzi dzinouya.
Mhinduro dzeSafe Series Connections
Kuti udzivise njodzi idzi, tevera mazano aya:
1.Tarisa Manufacturer Specifications:
Gara uchiona kana PCB yebhatiri yekudzivirira yakayerwa pamaapplications akatevedzana. Mamwe maPCB akagadzirwa zvakajeka kuti abate mavheti epamusoro mune akawanda-pack masisitimu.
2.Custom High-Voltage PCBs:
Kune mapurojekiti anoda mabhatiri akawanda munhevedzano (semuenzaniso, chengetedzo yezuva kana EV masisitimu), sarudza maseketi ekudzivirira ane akagadziridzwa akakwira-voltage MOSFET. Izvi zvinogona kugadzirwa kuti zvimire nemagetsi ese ekuseta kwako.
3.Balanced Design:
Ita shuwa kuti ese mabhatiri mapaketi munhevedzano anofananidzwa muhukuru, zera, uye hutano kuderedza njodzi yekusaenzana kukonzeresa kwekudzivirira nzira.
Pfungwa dzekupedzisira
Nepo kubatanidza mabhatiri e-voltage munhevedzano zvinogoneka nehunyanzvi, dambudziko rechokwadi riri mukuona kutidziviriro circuitry inogona kubata iyo cumulative voltage kusagadzikana. Nekuisa pamberi pezvikamu zvakatemwa uye proactive dhizaini, unogona kuyera zvakachengeteka mabhatiri masisitimu ako epamusoro-voltage application.
PaDALY, tinopacustomizable PCB mhinduroine high-voltage MOSFETs kusangana nepamusoro-soro-yekubatanidza zvinodiwa. Bata timu yedu kugadzira yakachengeteka, yakavimbika simba system yemapurojekiti ako!
