Abstract
A control apparatus includes a driver that outputs power based on a first control signal; a wireless power transmission system that is connected downstream of the driver, that receives first power, and that supplies second power to a motor through wireless power transmission; and a compensator that compensates a difference between a phase of the first control signal and a phase of current output from the wireless power transmission system.
Claims15
A control apparatus comprising:
- a driver configured to output power based on a first control signal;
- a wireless power transmission system configured to be connected downstream of the driver, to receive first power, and to output second power to a motor through wireless power transmission;
- and
- a compensator configured to reduce a difference between a phase of the first control signal and a phase of current output from the wireless power transmission system,
- wherein the compensator reduces the difference between the phase of the first control signal and the phase of the current output from the wireless power transmission system and a difference between an amplitude of the first control signal and an amplitude of the current output from the wireless power transmission system.

A method of controlling a control apparatus, the method comprising:
- outputting power based on a first control signal by a driver;
- receiving first power by a wireless power transmission system connected downstream of the driver and outputting second power to a motor through wireless power transmission;
- and
- reducing a difference between a phase of the first control signal and a phase of current output from the wireless power transmission system by a compensator,
- wherein the compensator reduces the difference between the phase of the first control signal and the phase of the current output from the wireless power transmission system and a difference between an amplitude of the first control signal and an amplitude of the current output from the wireless power transmission system.
