Abstract
A wireless power transmission system includes a power transmission apparatus, a power reception apparatus, a load driving apparatus, and a power control apparatus. The power control apparatus includes a direct current power supply, a main control circuit, and a communicator. Each time an operation load to be achieved by the load driving apparatus changes, the main control circuit updates a load instruction value for the load driving apparatus and a control parameter for adjusting a voltage of first alternating current power, the control parameter being used by the power transmission apparatus to convert first direct current power into the first alternating current power. The power transmission apparatus includes an inverter circuit and a power transmission control circuit that determines the voltage of the first alternating current power on the basis of the control parameter updated by the power control apparatus and that controls the inverter circuit.
