REDUCING THE IMPACT OF AN INDUCTIVE ENERGY TRANSFER SYSTEM ON A TOUCH SENSING DEVICE

摘要

A transmitter device for an inductive energy transfer system can comprise: a DC-to-AC converter connected to a transmitter coil to be operated; a first capacitor connected between the transmitter coil and one output terminal of the DC-to-AC converter; and a second capacitor connected between the transmitter coil and another output terminal of the DC-to-AC converter. One or more capacitive shields can be positioned between the transmitter coil and an interface surface of the transmitter device. A receiver device can comprise: a touch sensing device; an AC-to-DC converter connected to a receiver coil to be operated; a first capacitor connected between the receiver coil and one output terminal of the AC-to-DC converter; and a second capacitor connected between the receiver coil and another output terminal of the AC-to-DC converter. One or more capacitive shields can be positioned between the receiver coil and the interface surface of the receiver device.
