N2 - Some applications of wireless power transfer include transmitter located on a dynamic platform and static and mounted receiver. In such a case, transmitter compensation may be eliminated to minimize it. If receiver compensation should also be as simple as possible, none-series (NS) compensation topology is formed. This paper establishes a model of NS compensation topology and derives analytical expressions of primary and secondary currents based on both first harmonic approximation (FHA) based approach and differential equations (DE) based solution. It is shown that outcomes of FHA and DE methods are very close, justifying the use of simplified FHA-based approach. Coil-to-coil efficiency expressions are derived and optimal load matching factor of the topology is revealed. Simulations and experiments based on 400V, 1kW SN-compensated wireless power transfer link (WPTL) demonstrate excellent matching, validating the presented analysis.
