Abstract
Magnetic Resonance Coupling (MRC) based Wireless Power Transfer (WPT) system is gaining popularity due to its increased power transfer capacity. However, this method is very dependent on the alignment and resonant frequency of the transmitter and receiver coils. A little misalignment might cause the loss of the resonant point and a significant decrease in output power. This research examines the effect of misalignment of coils via coupling coefficient and the effect of operating frequency fluctuation on the output power of MRC-based WPT system for four fundamental compensation topologies. The investigation demonstrates that series-series (SS) topology is the most tolerant of misalignment of coils, whilst parallel-parallel (PP) topology is the most stable against operating frequency variation from resonant point. Parallel-series (PS) topology is the least tolerant to coil misalignment and operating frequency variations among all basic topologies.
