Title:
Contactless power transmission equipment and power transmission system
Document Type and Number:
Japanese Patent JP6350399
Kind Code:
B2
Abstract:
A non-contact electric power transmitting device (10) includes an electronic control unit (250) that is configured to perform; i) first control for controlling an electric power to be transmitted to a target electric power by adjusting a duty of an output voltage of an inverter (220), ii) second control for controlling a turn-on current representing an output current of the inverter (220) by adjusting the drive frequency, the output current being an output current at a time when the output voltage rises, , and iii) adjusting the duty and the drive frequency such that a current supplied from the inverter (220) to an electric power transmitting unit (240)decreases within the range in which the turn-on current is equal to or smaller than a limit value, while performing the first control.
