Power Electronic Converters

1Introduction

1.1 Introduction

For a long time, voltage-type sources such as storage battery, AC grid, and output-voltage-regulated converters have dominated as an input source for power electronic converters [1,2]. These sources are usually referred to as rigid sources, since the load has limited influence on their operating voltage. Both awareness on the depletion of fossil fuel reserves and their impact on the observed climate changes have accelerated the utilization of renewable energy sources, for example, wind and solar [3]. Effective large-scale utilization of these energy sources requires the use of grid-interfaced power electronic converters [4,5]. It has been recently concluded [6,7] that the power electronic converters used in ...
