Zusammenfassung:A juvenile product includes a power adapter comprising a first AC-to-DC converter to generate a DC transmission voltage from a line power source, and a power cable coupled to the power adapter and configured to carry the DC transmission voltage. A power transmitter coupled to the power cable includes a transmitter coil and a DC-to-AC converter coupled to the transmitter coil such that an AC current flows through the transmitter coil based on the DC transmission voltage. A power supply includes a receiver coil configured for generation of induced current in the receiver coil via inductive coupling with the transmitter coil, and further includes a second AC-to-DC converter coupled to the receiver coil to generate DC power based on the induced current. An electrical load coupled to the power supply is configured for operation via the DC power.
