电源往往是我们在电路设计过程中最容易忽略的环节。其实,作为一款优秀的设计,电源设计应当是很重要的,它很大程度影响了整个系统的性能和成本。这里,只介绍一下电路板电源设计中的电容使用情况。这往往又是电源设计中最容易被忽略的地方。很多人搞ARM,搞DSP,搞FPGA,乍一看似乎搞的很高深,但未必有能力为自己的系统提供一套廉价可靠的电源方案。这也是我们国产电子产品功能丰富而性能差的一个主要原因,根源是研发风气吧,大多研发工程师毛燥、不踏实;而公司为求短期效益也只求功能丰富,只管今天杀鸡饱餐一顿,不管明天还有没有蛋,“路有饿死骨”也不值得可惜。言归正转,先跟大家介绍一下电容。大家对电容的概念大多还停留在理想的电容阶段,一般认为电容就是一个C。却不知道电容还有很多重要的参数,也不知道一个1uF的瓷片电容和一个1uF的铝电解电容有什么不同。实际的电容可以等效成下面的电路形式: C:电容容值。一般是指在1kHz,1V 等效AC电压,直流偏压为0V情况下测到的,不过也可有很多电容测量的环境不同。但有一点需注意,电容值C本身是会随环境发生改变的。ESL:电容等效串联电感。电容的管脚是存在电感的。在低
