NCP1654(PFC)+UCC25600(LLC),45V/1000W 输出,老化时 烧Q10/Q11管子。

Other Parts Discussed in Thread: UCC25600

Hi 您好:

        在设计一个45V/1000W输出的开关电源,PFC用NCP1654,LLC用UCC25600,老化时发生烧Q10/Q11管子。附件为原理图,变压器,谐振电感设计等,尝试过把Q10/Q11由28N50换成 46N60,还是会烧Q10/Q11。1000w-1原理图.pdf1000w-2原理图.pdf变压器YT-ER4220(150uH)B285-48-12V.pdf谐振电感 YL-RM10(30UH)A531.pdf
