1. A contactless power transfer system comprising:
- a first power exchanging coil configured for contactless exchange of power;
a power mating coil operatively coupled to a switching unit; and
a controller operatively coupled to the switching unit, wherein the controller is configured to control switching operations of the switching unit to actively control a magnitude and a phase of current in the power mating coil to match an impedance of the first power exchanging coil and enable a contactless exchange of power.

Abstract
A contactless power transfer system is provided. The contactless power transfer system includes a first power exchanging coil configured to exchange power, a power mating coil operatively coupled to a switching unit, and a controller operatively coupled to the switching unit. The controller is configured to control switching operations of the switching unit to actively control a current in the power mating coil to match an impedance of the first power exchanging coil and enable the exchange of power.
