Claim 0:
1. A combined inductive and capacitive system for producing a dynamic wireless power transfer with reduced fluctuation of an output power for charging of an electric vehicle in motion along a ground path, the system comprising:
an inductive power transfer (IPT) system comprising a multiplicity of transmitter coils spaced along the ground path, and at least one receiver coil installed on a chassis of the electric vehicle;
a capacitive power transfer (CPT) system comprising a multiplicity of capacitive coupler transmitters spaced along the ground path, each respective capacitive coupler transmitter alternatingly positioned between respective transmitter coils, and using a common earth ground along the ground path as the second plate to form a multiplicity of two plate transmitters, and a first receiver plate installed on the chassis of the electric vehicle, the chassis comprising a sufficient mass of aluminum to function as the second plate to form a two plate receiver;
an LCC compensation network connected to the IPT system;
an LCC compensation network connected to the CPT system; and
an inverter configured and adapted to produce a square wave input voltage, VIN, to supply the LCC compensation network and drive the IPT system, and to supply the LCLC compensation network and drive the CPT system,
the dynamic wireless power transfer comprising the summation of an IPT system power transfer and a CPT system power transfer, and
the CPT system power transfer configured and adapted to be at its maximum when the IPT system power transfer is at its minimum, such that the fluctuation of the output power is within ±6%.
