| Summary: | This dissertation focuses on the design and analysis of load-independent Class EF
inverters for high-frequency wireless power transfer (WPT) applications. Three
distinct inverter topologies are examined: the basic Class EF inverter, the Class EF
inverter with Series-Series (SS) compensation, and a simplified Class EF inverter with
SS compensation. The goal is to evaluate the performance of these circuits under
varying load conditions and to determine the effectiveness of SS compensation in
minimizing harmonic distortion and maintaining output voltage stability. Simulations
were conducted using LTspice, and the results are analyzed in terms of output voltage
amplitude and Total Harmonic Distortion (THD). The study demonstrates that the SS
compensated Class EF inverter exhibits superior stability and lower THD, making it a
more reliable solution for wireless power transfer systems. The simplified circuit,
though slightly less efficient, offers a more streamlined design with reduced
component count. |
