  • Power transmission system
    Patent number: 10065510
    Abstract: The power transmission system includes a power transmitting device that transmits AC power and a power receiving device that receives the AC power. The power receiving device includes a rectifier that converts the received AC power into DC power, a DC converter that performs DC conversion on the DC power output from the rectifier, and a power-receiving side controller that calculates, based on an input voltage of the DC converter, a current command value making input impedance of the DC converter equal to a preset value and controls the DC converter so that an input current of the DC converter equals the current command value.
    Type: Grant
