Abstract
An inductive power transmitter comprises a first primary inductor configured to inductively couple a first secondary inductor and configured to hold a first variable electrical potential. The transmitter also comprises a second primary inductor configured to inductively couple a second secondary inductor that is configured to hold a second variable electrical potential. The primary inductors are arranged in an overlapping fashion on a substrate forming a charging surface. The first primary inductor is connected to a first driver capable of providing the first variable electrical potential, and the second primary inductor is connected to a second driver capable of providing the second variable electrical potential in a first embodiment while a second possibility is that the first primary inductor is connected to a first driver capable of providing the first variable electrical potential, and the second primary inductor comprises capacitor and is not connected to a driver.
