Summary
This chapter addresses techniques for extending the charging range of PT-symmetric WPT systems. It begins with an introduction to range extension methods and then explores the use of S/SLDC high-order topologies for improved performance. The chapter includes system analysis, modelling, and comparison with other topologies, focusing on negative resistance design to enhance range. Additionally, it presents flexible charging range extension methods, such as autonomous on-off keying modulation schemes, and discusses their system output characteristics and control algorithm implementation. Experimental verification supports the proposed methods, showcasing advancements in expanding the operational range of PT-symmetric WPT systems.
