Wireless power supply apparatus, filter unit and power supply apparatus for robot using the filter unit
First Claim
1. A wireless power supply apparatus comprising:
- a power transmission coil to which electric power is supplied from a power supply unit;
a power reception coil that functions as a repeater configured to (i) receive electric power in a non-contact manner by magnetic resonance with the power transmission coil and (ii) relay transfer of the electric power from the power transmission coil;
an actual load connected to the power reception coil and powered by the electric power received by the power reception coil; and
an auxiliary load inserted parallel to the power reception coil and the actual load and configured to form a closed circuit with the power reception coil when supply of the electric power to the actual load is interrupted to be in an open state, so as to ensure the repeater function of the power reception coil irrespective of activation conditions of the actual load.

Abstract
A wireless power supply apparatus includes a power reception coil, an actual load and an auxiliary load. The power reception coil functions as a repeater for receiving electric power in a non-contact manner by magnetic resonance with a power transmission coil to which electric power is supplied from a power supply unit and relaying transfer of the electric power from the power transmission coil. The actual load is connected to the power reception coil and is powered by the electric power received by the power reception coil. The auxiliary load is inserted parallel to the power reception coil and the actual load and forms a closed circuit with the power reception coil when supply of the electric power to the actual load is interrupted to be in an open state.
