REVIEW OF IMPEDANCE SOURCE POWER CONVERTER FOR ELECTRICAL APPLICATIONS

Power electronic converters have been intensely researched and developed over the last decades. New solutions and topologies have still been in high demand in order to increase the conversion system reliability and efficiency with decreased cost, volume, and weight. Impedance source converter is one of the most important power electronic converters that can be used for ac–dc, ac–ac, dc–dc, and dc–dc conversion which can be used for various applications like photovoltaic systems, wind energy systems, electric vehicles and fuel cell applications. This paper presents a review of Z-source converters and their implementation with new structures having improved features, incorporating emerging control strategies and detailed analysis of applications.
