Abstract:

Impedance-source networks have gained attention as promising power conversion stages owing to their flexible step-up/down conversion ratios and high reliability with shoot-through protection. However, there are still limitations that hinder their further applications in renewable energy systems. This chapter provides an overview of Z-source converters, a type of impedance-source converter, and their classifications. It discusses the limitations of traditional voltage source inverters and current source inverters, leading to the emergence of Z-source converters. The features, operation principle, and classification of various topologies are then discussed, including DC/DC converters, DC/AC inverters, two-level H-bridge topologies, multilevel/neutral point clamped AC/AC converters, and AC/DC converter topologies. The chapter highlights the need to design and optimize impedance source networks and presents an example of a quasi-Z-source inverter design. Finally, the chapter discusses possible future directions and applications of Z-source converters.
