Study on Ripple Characteristics of Uncontrolled Rectifier Circuit

Abstract

The ripple in DC charging is a basic indicator of the voltage quality, which is related to the filter capacitor and external load. In this paper, the single-phase bridge rectifier circuit is used as the research object. It analyzes the generation process of ripple voltage and derives the expression of ripple voltage. And the effects of filter capacitor C, voltage U and external load R on the ripple coefficient are simulated and analyzed, as well as the spectrum distribution characteristics of the ripple.
