【摘要】 随着设备性能的提高,电源输出纹波(PARD)对设备性能的影响也越来越显著。抑制开关电源纹波(PARD)的方法有很多,在开关电源输出后加低压差线性稳压器是最有效的方法。介绍了将低压差线性稳压器加入高压电源的方法,理论分析和实际测试证明了该方法的有效性和良好的工程应用前景。更多还原

【Abstract】 Along with the improvement of equipment performance,the influence of power source output periodic and random deviation(PARD)on equipment performance becomes more and more evidently.There are many ways to restrain the PARD of switching power source,the best effective way is to add low dropout regulator(LDO)after switching power source output.This paper introduces the method to add LDO to high-voltage power source.Theoretical analysis and actual test prove the validity of this method and favorable prospect of engineering application.更多还原
