请叫一个电容与电阻并联时的问题请看图:
总电压应该是直流与交流的叠加,叠加后的电压应该也是一个交流,
因为C1与R1是并联的,那么C1和R1两端的电压也都是总的电压,也
就是两个电源的叠加交流电压,那么C1和R1的 LLC等效变换,电感极性看了一篇关于LLC的文章,关于等效后电感的极性,电路上电感是左正,右负。等效后变成左负右正,是什么原因呢
最好把原文贴出来,猜不出来的

对于一个初次搞电源的人来说,对于0欧姆电阻大概都不懂的,觉得没啥用的巨多吧,但是还真有一些地方会用到哦,这也算是一个冷知识了。
可能 IR 3584 4相 BUCK 电源中遇到 的问题在一定的负载频率和LOAD STEP 条件下 测试瞬态响应transient的时候 ,输出电压的上冲和下冲都很大,几乎快超过SPEC 了。由于PK -PK 很大,没办法通过调电压OFFSET
