Title:
Contactless power transmission equipment and power transmission system
Document Type and Number:
Japanese Patent JP6304152
Kind Code:
B2
Abstract:
A power supply ECU executes transmission power control for controlling transmission power to target power by adjusting the duty of an output voltage of an inverter and turn-on current control for controlling a turn-on current to a target value by adjusting the drive frequency of the inverter. When a current supplied from the inverter to a power transmission unit exceeds a predetermined limit value during adjustment of the drive frequency of the inverter by the turn-on current control, the power supply ECU decreases target power in the transmission power control.
