Juvenile Product Inductive Power Transfer
First Claim
1. A juvenile product comprising:
- a power adapter comprising a first AC-to-DC converter to generate a DC transmission voltage from a line power source;
a power cable coupled to the power adapter and configured to carry the DC transmission voltage;
a power transmitter coupled to the power cable and comprising 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 comprising a receiver coil configured for generation of induced current in the receiver coil via inductive coupling with the transmitter coil, and further comprising a second AC-to-DC converter coupled to the receiver coil to generate DC power based on the induced current; and
an electrical load coupled to the power supply and configured for operation via the DC power.

Abstract
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.

14. A method of powering a juvenile product, the method comprising the steps of:
-
converting a power line voltage to generate a DC transmission voltage; delivering the DC transmission voltage via a power cable to a transmitter; developing an AC current based on the DC transmission voltage for a transmitter coil of the transmitter; positioning the transmitter coil relative to a receiver coil to induce current in the receiver coil based on the AC current in the transmitter coil via inductive coupling between the transmitter and receiver coils; and generating DC power for an electrical load of the juvenile product based on the current induced in the receiver coil.
