Comparative Analysis Topologies with Coupling Capacitor Double Resonance Circuit for ECPT System

The different topologies of coupling capacitor double resonance circuit are widely used in electric-field coupled power transfer system. But the different topologies have different application conditions and application fields. The characteristic impedances of 2-port networks with different topologies are analyzed, and the optimization parameters with different topologies are derived by impedance matching. The frequency characteristic of load power with different coupling capacitor and load are plot by comparative analysis.
