求助:电源测试方法

求助:电源测试方法
我们做了一个3.3V 25A 的电源(48V输入),想要进行测试,请高手指点一下都要进行哪些项目测试,测试方法?
谢谢

Test item
You should test the following item:
Efficiency, ripple/noise, regulation, thermal (important item), dynamic/transient response, hot swap etc. Did you design protecion circuit, if so, you need test OVP OCP UVP short, etc, as I know, for 48Vdcin power need to design input UVP, and need to limit input current, isn\'t it?

佩服!
让我来顶一下arthur,不介意吧!Overload好象也是要的.EMI,EMC,安规等等,烦死你!

also need include the input OVP at 48V dc in.

Over load is Over current i.e. OCP

噪声的测试?
电源的纹波的测试标准是什么? 具体怎么测试输出纹波及噪声,我的电源的输出纹波怎么那么大130mV左右,请回复测试输出纹波及噪声的标准测法.

好像还有hold-on-time
就是初级断电后输出保持时间,好像要求是48ms吧?不知道对不对

我专门发了贴字的
叫:开关电源的噪声测试

hold up time要求
一般为一个AC周期,16mS或20mS,48mS的要求要不是系统有特殊要求就是脑袋进水了.
