RC Snubber Design for SMPS Protection

By InCompianceMag Posted On 1.2.2019

Source: InComplianceMag article

by Bogdan Adamczyk and Bill Spence.

Fundamentals of Inductive Switching and RC Snubber Impact
This is the first of the two articles devoted to the topic of an RC snubber design. In Part I we discuss the fundamentals of the inductive switching and the need for circuit protection. The impact of an RC snubber on the circuit performance is demonstrated through a series of simulations. Part II (to appear in the March 2019 issue of In Compliance) will address the systematic process of the snubber circuit design, together with the simulation and verification through the laboratory measurements.

An introduction to insertion loss and filter capacitor performance

By Capacitor Faks Posted On 2.1.2019

Source: Capacitor Faks blog

by Anthony Kenny. Capacitors are used in both analog and digital circuits to remove unwanted signals. The filtering performance of a capacitor or filtering circuit is commonly described in terms of insertion loss. Some of the factors that significantly affect the insertion loss performance of a filtering circuit include configuration of the filtering elements, impedance, and load current. (more…)
