PD Charger

Kuthamangitsa kwachangu kwa GaN PD kumapangitsa kuti magetsi azitulutsa kwambiri kudzera mumagetsi okwera komanso apano, kuti azitha kuyitanitsa mwachangu. Mphamvu yake yotulutsa imatha kufika ku 21V, ndipo zotsatira zake zamakono zimatha kufika 5A; Chifukwa chake, capacitor yotulutsa imasankha voteji ya 25V, mphamvu yayikulu, ma capacitor otsika a ESR. Kuchuluka kokwanira kumatha kutsimikizira thandizo la DC, ndipo ESR yotsika mokwanira imatha kutsimikizira kusefa. Komabe, ma 25V olimba a aluminiyamu electrolytic capacitors ali ndi vuto lotere: kutha kupirira kugwedezeka kwakusintha sikukwanira. Deta yoyesera ndi ndemanga zamsika zikuwonetsa kuti mutatha kulipiritsa mobwerezabwereza ndi kutulutsa masiwichi (kuphatikiza koma osalekeza kutulutsa pafupipafupi komanso kuthamangitsa mwachangu), ma 25V olimba a aluminium electrolytic capacitors adzawona kuwonongeka kwamphamvu, limodzi ndi ESR yofulumira. kuwonongeka kwa mphamvu yothandizira DC ya ma capacitor olimba, kuthamanga kwachangu kudzachepetsedwa kwambiri, ndipo kuyitanitsa mwachangu sikudzakhalanso kuthamanga! Kukwera kofulumira kwa ESR kudzetsa kutulutsa kokulirapo kwa kulipiritsa mwachangu, komwe kumabweretsa zovuta zambiri! Ndi kuyitanitsa mwachangu, nthawi zambiri mumakumana ndi kuzimitsidwa kwamagetsi mukamadula ndikutsitsa, ndiye kuti kulipiritsa mwachangu kuyenera kupirira kuyitanitsa ndi kutulutsa pafupipafupi! Poganizira izi, apa timalimbikitsa cholimba cholimba cha aluminiyamu electrolytic capacitor yopangidwa ndi YMIN yomwe imalimbana ndi kusinthasintha pafupipafupi komanso kutulutsa. Makhalidwe ake amachitidwe ndi awa.
