7Introduction to Current-Fed Converters

7.1 Introduction

Majority of the converter power stages developed by far are devoted to the voltage-fed applications due to the dominance of voltage as the main property of the energy sources [1,2]. There are, however, also energy sources having current as their main property such as photovoltaic generators [3–5] and superconductive magnetic energy storage (SMES) devices [6,7]. As a consequence, there also have to be power electronic converters, which can accept a current source as their main input source [2]. Even the concept of duality in circuit theory would imply their existence due to the dual nature of voltage and current [8].

The current-fed converters can be implemented from the corresponding ...
