Ishaja ye-PD

Ngokuthandwa kwamadivayisi eselula kanye nesidingo sabantu sokushaja okusheshayo, ubuchwepheshe bokushaja okusheshayo be-Power Delivery (PD) buye kancane kancane baba yinto eyinhloko yezixazululo zokushaja kwamadivayisi eselula. Njengengxenye ebalulekile ye-elekthronikhi, ama-capacitor anezinhlelo zokusebenza eziningi kanye nezindima ezibalulekile emkhakheni wokushaja okusheshayo kwe-PD.

Okokufaka: I-capacitor ye-electrolytic ye-aluminium ewuketshezi ephezulu

Izinzuzo ze-YMIN

Umthamo ophezulu

Ukwenziwa kube kuncane

Ukuvuza okuphansi kwamanje

I-ripple ephezulu

Impedance ephansi

Ukulwa nombani

Imakethe yokushaja okusheshayo kwe-gallium nitride iyachuma. Ngokusebenza kwamandla aphezulu kwamashaja okushaja okusheshayo kwe-gallium nitride, uchungechunge lwe-KCX oluyi-liquid olunamandla aphezulu, olunamandla amakhulu noluncane oluthuthukiswe futhi lwakhiqizwa yi-YMIN lusebenzisa ubuchwepheshe benqubo obuvuthiwe obunelungelo lobunikazi, lwamukela izinto ezintsha, futhi ludlula ubuchwepheshe be-capacitor. Izithiyo, izinga lokuhluleka komshini wonke lilawulwa ku-15PPM, ukuze kufezwe ukuvumelana okuhle kakhulu kanye nokuthembeka okuzinzile kakhulu.

Umphumela: I-capacitor ye-electrolytic ye-aluminium eqinile enamandla aphansi

Izinzuzo ze-YMIN

Umthamo ophezulu

Ukushaja okusheshayo kwe-GaN PD kufinyelela ekukhishweni kwamandla aphezulu nge-voltage ephezulu kanye nogesi ophezulu, ukuze kufezwe ukushaja okusheshayo. I-voltage yayo yokukhipha ingafinyelela ku-21V, kanti ugesi wayo wokukhipha ungafinyelela ku-5A; ngakho-ke, i-capacitor yokuhlunga yokukhipha izokhetha i-voltage engu-25V, umthamo omkhulu, ama-capacitor aqinile e-ESR aphansi. Umthamo omkhulu ngokwanele ungaqinisekisa ukwesekwa kwe-DC, kanti i-ESR ephansi ngokwanele ingaqinisekisa umphumela wokuhlunga. Kodwa-ke, ama-capacitor e-electrolytic e-aluminium eqinile angu-25V avamile anenkinga enkulu: ikhono lokubekezelela ukushaqeka kokushintsha alanele. Idatha yokuhlola kanye nempendulo yemakethe ikhombisa ukuthi ngemva kokushaja nokukhipha amaswishi okuphindaphindiwe (kufaka phakathi kodwa kungagcini ekukhipheni i-plug njalo kanye nokuxhuma ukushaja okusheshayo), ama-capacitor e-electrolytic e-aluminium eqinile angu-25V avamile azobhekana nokubola komthamo okusobala, okuhambisana ne-ESR esheshayo. Lokhu kuzoholela ekuwohlokeni kwamandla okusekela e-DC ama-capacitor aqinile, isivinini sokushaja okusheshayo sizoncishiswa kakhulu, futhi ukushaja okusheshayo ngeke kusakwazi ukushaja okusheshayo! Ukunyuka okusheshayo kwe-ESR kuzoholela ekuqhumeni okukhulu kokukhipha ukushaja okusheshayo, okuzoletha imiphumela eminingi emibi! Ngokushaja okusheshayo, uzovame ukubhekana nokuphazamiseka kukagesi lapho uxhuma futhi ukhipha i-plug, ngakho-ke ukushaja okusheshayo kumele kukwazi ukumelana nokushaja nokukhipha i-charge njalo! Ngenxa yalokhu, lapha sincoma i-capacitor eqinile ye-aluminium electrolytic eyenziwe yi-YMIN emelana nokushaja nokukhipha i-charge njalo. Izici zayo zokusebenza yilezi ezilandelayo.
