電源紋波的產生、測量和抑制

摘要：電源紋波是電源檢測的重要指標，紋波電壓對電子電路會產生影響，在設計電子產品時我們都要考慮紋波的影響。本文從實踐中歸納了電源紋波測量和抑制方法等內容。 敘詞：電源紋波 紋波產生 紋波測量 抑制方法 Abstract：Power ripple is one of the most important criteria for power supply measurement, and ripple voltage affects electronic circuit, thus ripple can be one factor to be considered when we design electronic products. This article summarizes from practice ways to measure and suppress power ripple. Keyword：Power Ripple, Emergence of Ripple, Ripple Measurement, Method of Suppression
