Supercapacitors for surge absorption

Abstract

Supercapacitor-based circuits have long time constants. This property can be usefully utilized in surge-absorbing circuits, despite the fact that they are very low voltage devices. Technique called supercapacitor-assisted surge absorber (SCASA) is discussed, comparing its performance with a traditional commercial surge absorber.

7.1 Introduction

Supercapacitors can be used in applications where they are not typically used as energy storage devices or in hybridized form with batteries. In Chapter 6, we used it as a theoretically lossless voltage dropper in a DC-DC converter, and in this chapter supercapacitor’s ability ...
