Abstract
The analysis of a two-coil wireless power transfer (WPT) system can be done in different forms including using two-port network representations. Here, we opt to use a transmission matrix-based model and revert to symbolic math analysis CAD tools to derive closed form expressions (without any simplifying assumptions) for the complex power supplied by the system with and without an input compensation capacitor. The important role played by this capacitor in minimizing the re-active power loss is demonstrated and numerical simulations using typical values from two WPT systems are provided.
