A thermal management system for an electromagnetic induction-power transfer system. The system may include a charging apparatus including a housing that defines an interface surface. An accessory or induction-power consuming apparatus may be positioned proximate to the interface surface. The housing of the charging apparatus may include a power source and a power-transferring coil coupled to the power source and positioned below the interface surface. A thermal mass may be positioned within the housing and spaced apart from the interface surface. The housing may include a thermal path that is configured to conduct heat from the interface surface to the thermal mass.

Temperature management for inductive charging systems

A transmitter device for an inductive energy transfer system can include a DC-to-AC converter operably connected to a transmitter coil, 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 include a touch sensing device, an AC-to-DC converter operably connected to a receiver coil, 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 an interface surface of the receiver device.
