But through the calculation formula provided by TIDA-020031
ΔILOUT=60A at 3.6KW
ICOUT_RMS =ΔILOUT/√3=34.64A
B41896C7397M provides ripple current 1.82A
ICOUT_RMS =1.82A*4=7.28A<34.64A
Is the ripple current of the output capacitor suitable for the design?
can you tell me? thanks for your help
TIDA-020031 3.6KW 提供的電路圖中,
1.(390uF)B41896C7397M提供的最大允許紋波電流在1.82A,四顆並聯有7.28A,請問這樣是能滿足3.6KW(34.64A)的嗎?
2.390uF*4已經有12個10uF/35V的陶瓷電容並聯,這樣是否足夠呢?
請幫忙協助我
謝謝
HI:
我了解390uF*4並聯12個10uF/35V的陶瓷電容會降低ESR值。
但關於紋波電流問題,電解電容390uF*4(7.82A)並聯MLCC 10uF*12是會增加紋波電流能力嗎?
能符合3.6KW(34.64A)嗎?或是我應該在并聯更多的390uF來增加紋波電流能力嗎?來防止電解電容溫升問題
請幫忙協助我
謝謝
