开关电源进行调试该怎么做

Source: Time:2019-06-17 15:40:28 views:

 开关电源正常的工作是保护好电器的必要条件,但是如何来正确的调整好开关电源的输出,这就涉及到怎么进行电源电路怎么进行调试的问题。


 (1)电源电路的输出通过低阻值大功率电阻接到板内,这样在不焊电阻的情况下可以先做到电源电路的先调试,避开后面电路的影响。


  (2)一般来说开关控制器是闭环系统,如果输出恶化的情况超过了闭环可以控制的范围,开关电源就会工作不正常,所以这种情况就需要认真检查反馈和采样电路。特别是如果采用了大ESR值的输出电容,会产生很多的电源纹波,这也会影响开关电源的工作的。
