Omunye umakhasimende ovela enkampanini eqalayo yezinto zikagesi watusa inqubo yethu yokwenza ngokwezifiso, ethi ithimba lethu lithathe izidingo zabo ezingacacile futhi lanikeza i-PMIC prototype ehloliwe ngokuphelele phakathi namaviki ayisithupha, isikhathi ababecabanga ukuthi asinakwenzeka. Umugqa oqondile kulezi zifakazelo ukuthi ukuzibophezela kwethu ekuqondeni ukusetshenziswa komakhasimende, hhayi nje ukuthengisa umkhiqizo osewukhona, yilokho okusenza sihluke. Ngokuhlaziya izinhlobo ezithile zamasekhethi kanye nama-topology amandla adingekayo kuphrojekthi ngayinye, sihlinzeka ngezixazululo ezenzelwe ukusetshenziswa kwangempela kunendlela evamile eyodwa efanele wonke umuntu. Amakhasimende ethu abuye akwazise ukucaca kwedatha yethu yokuhlola, ehlanganisa izilinganiso ezinemininingwane zamajika okusebenza kahle, impendulo yomthwalo wesikhashana, kanye nama-spectra omsindo athathwe kusetshenziswa izilungiselelo ze-lpf low pass filter ezilinganisiwe. Leli zinga lemibhalo linikeza amathimba omklamo ukuzethemba ukuze aqhubekele ngqo ekukhiqizeni ngaphandle kokuhlola okuningi ohlangothini lwawo. Ukwethembana esikwakhe ngokusebenzisana okungamakhulu ezinkulungwane okuphumelelayo kuyimpahla yethu ebaluleke kakhulu, futhi sisebenza kanzima nsuku zonke ukuze sikugcine futhi siqinise.

Ukukhetha i-Power Management IC efanele yisinqumo esithinta zonke izici zokusebenza komkhiqizo we-elekthronikhi, kusukela empilweni yebhethri nokuziphatha kokushisa kuya ekuthembekeni nasezindlekweni. Kulo lonke leli athikili, sihlole indlela ama-PMIC anamuhla asebenzisa ngayo izinhlobo ezahlukene zamasekhethi, okuhlanganisa i-parallel circuit ne-series circuit topologies, izigaba ze-full wave rectifier, kanye ne-lpf low pass filter networks ukuze kulethwe izixazululo zamandla ezihlanzekile, eziphumelelayo, nezincane. Iphothifoliyo yethu yomkhiqizo ibhekana nazo zonke izinhlobo zezinhlelo zokusebenza, kusukela kumagajethi abathengi kuya emishinini yezimboni, izinhlelo zezimoto, kanye namadivayisi e-IoT axhumene, anemininingwane engahlelwa ukuze ihambisane nezidingo zakho ngqo. Amazinga ethu okuqinisekisa ikhwalithi nokuhlola esiwasebenzisayo aqinisekisa ukuthi wonke umshini ophuma endaweni yethu uhlangabezana namazinga aphezulu kakhulu okuthembeka nokusebenza. Izinzuzo zethu zokuncintisana ezindlekweni, isivinini sokulethwa, kanye nokusekelwa kwezobuchwepheshe zisekelwa yithimba lonjiniyela abanolwazi abazimisele ngempela empumelelweni yakho. Njengomhlinzeki ogunyaziwe wezixazululo zokuvikela amasekhethi ze-Eaton Bussmann kanye nomlingani othembekile ekuphathweni kwamandla, i-深圳市华川高科电子有限公司 ihlanganisa ubuchwepheshe obujulile nendlela egxile kumakhasimende ebeka phambili ubudlelwano besikhathi eside kunokuhweba kwesikhashana. Siyakumema ukuthi uhloleIkhaya ikhasi ukuze uthole umbono wamakhono ethu, buyekeza i-Imikhiqizo ikhasi ukuze uthole idatha yobuchwepheshe enemininingwane, bese uxhumana nathi nge-Xhumana Nathi ikhasi lokuxoxa ngephrojekthi yakho elandelayo. Uma ubambisana nathi, uthola okungaphezu komhlinzeki wezingxenye: uthola umlingani ozinikele emzameni wokudala imikhiqizo ye-elekthronikhi engcono, esebenza kahle, futhi enokuncintisana. Sivumele sikusize ukuthi unike amandla ikusasa.
