POWER TRANSMISSION CONTROL DEVICE, POWER TRANSMITTING DEVICE, POWER-TRANSMITTING-SIDE DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM
First Claim
1. A power transmission control device that controls power transmission of a power transmitting device of a non-contact power transmission system, the non-contact power transmission system transmitting power from the power transmitting device to a power receiving device via non-contact power transmission through a primary coil and a secondary coil that are electromagnetically coupled, the power transmission control device comprising:
- a power-transmitting-side control circuit that controls power transmission to the power receiving device;
an actuator control circuit that controls the operation of an actuator, the actuator moving the position of the primary coil in an XY plane;
a relative position detection signal generation circuit that generates a relative position detection signal relating to the primary coil and the secondary coil based on a coil end voltage or a coil current of the primary coil; and
a primary coil position control circuit that causes the actuator control circuit to move the position of the primary coil in the XY plane so that the relative positional relationship between the primary coil and the secondary coil indicated by the relative position detection signal is within an allowable range.

Abstract
A power transmission control device provided in a non-contact power transmission system includes a power-transmitting-side control circuit that controls power transmission to a power receiving device, an actuator control circuit that controls the operation of an actuator that moves the position of a primary coil in an XY plane, a relative position detection signal generation circuit that generates a relative position detection signal relating to the primary coil and a secondary coil based on a coil end voltage or a coil current of the primary coil, and a primary coil position control circuit that causes the actuator control circuit to move the position of the primary coil in the XY plane so that the relative positional relationship between the primary coil and the secondary coil indicated by the relative position detection signal is within an allowable range.
