PD Charger

Gusharija byihuse bya GaN PD bituma ingufu nyinshi zisohoka binyuze mu muvuduko mwinshi w'amashanyarazi n'umuvuduko mwinshi w'amashanyarazi, bityo bigatuma habaho gusharija byihuse. Umuvuduko wayo ushobora kugera kuri 21V, kandi umuvuduko wayo ushobora kugera kuri 5A; bityo, capacitor ya filter isohoka izahitamo voltage ya 25V, ubushobozi bunini, na capacitor nto ya ESR nke. Ubushobozi buhagije bushobora kwemeza ko DC ishyigikiwe, kandi ESR nkeya bihagije ishobora kwemeza ko ikoreshwa. Ariko, capacitor zisanzwe za 25V solid aluminum electrolytic zifite ikibazo gikomeye: ubushobozi bwo kwihanganira impanuka zo guhindura ntabwo buhagije. Amakuru y'igerageza n'ibitekerezo by'isoko bigaragaza ko nyuma yo gusharija no gusohora switch kenshi (harimo ariko bitagarukira gusa ku gukuraho no gufunga kenshi charger yihuse), capacitor zisanzwe za 25V solid aluminum electrolytic electrolytic zizabona kwangirika kugaragara, biherekejwe na ESR yihuta. Ibi bizatuma ubushobozi bwa DC bwo gushyigikira capacitor zikomeye bugabanuka cyane, kandi charger yihuse ntizongera kuba charger yihuse! Kuzamuka kwihuse kwa ESR bizatuma umusaruro mwinshi wo charger yihuse usohoka, bizazana ingaruka mbi nyinshi! Mu gihe ukoresha amashanyarazi yihuta, akenshi uhura n'ikibazo cyo kubura umuriro iyo ukoresha amashanyarazi cyangwa ukayakuramo, bityo amashanyarazi yihuta agomba kuba ashobora kwihanganira gusharija no kuyasohora kenshi! Kubera iyo mpamvu, hano turagusaba capacitor ikomeye ya aluminium electrolytic yakozwe na YMIN irwanya gusharija no kuyasohora kenshi. Imiterere yayo ni iyi ikurikira.
