A transmitter device (202) for an inductive energy transfer system can include a DC-to-AC converter (502) operably connected to a transmitter coil (504), a first capacitor (C P1 ) connected between the transmitter coil (504) and one output terminal (506) of the DC-to-AC converter (502), and a second capacitor (C P2 ) connected between the transmitter coil (504) and another output terminal (508) of the DC-to-AC converter (502). One or more capacitive shields can be positioned between the transmitter coil (504) and an interface surface (214) of the transmitter device (202). A receiver device (204) can include a touch sensing device (516), an AC-to-DC converter (512) operably connected to a receiver coil (510), a first capacitor (C S1 ) connected between the receiver coil (510) and one output terminal of the AC-to-DC converter (512), and a second capacitor (C S2 ) connected between the receiver coil (510) and another output terminal of the AC-to-DC converter (512). One or more capacitive shields can be positioned between the receiver coil (510) and an interface surface (212) of the receiver device (204). |
