FIELD: electricity.
SUBSTANCE: electrical power transmitting device transmits electrical power to the electrical power receiving device in a non-contact manner. The electrical power transmitting device includes an inverter, a power transmitting unit and an electronic control unit. The electronic control unit is configured to determine whether the phase of the output current flowing from the inverter to the power transmitting unit is outrunning the output voltage, and of such adjustment of the AC power frequency in the direction of decreasing the advance angle of the current phase that the current phase is delayed relative to the output voltage when the current phase is advancing the output voltage.
EFFECT: preventing the regenerating current flow and reducing the probability of abnormal heating or malfunction in the electrical power transmitting device.
