15.1 Introduction

Power electronic converters are currently employed in numerous industrial and household applications such as motor drives and power system operation and control (FACTS (flexible AC transmission systems), HVDC (high-voltage DC), static var compensation, power quality improvement, active filtering, the linking of two different frequency power systems such as 50 Hz and 60 Hz, etc.). The main function of a power electronic converter is to convert uncontrolled power to controlled power. Broadly classified power electronic converters are AC/DC, DC/AC, DC/DC, and AC/AC. The classical approach to AC/AC conversion is the use of thyristor devices called cycloconverters. The major shortcoming of such topology is its limited range of output frequency (only one-fourth of the input frequency value). Another topology is based on bidirectional power switches that are arranged in the form of array or matrix called matrix converters [1–3]. Matrix converters transform uncontrolled AC (fixed voltage amplitude, fixed frequency) into ...
