FIELD: electrical engineering.
SUBSTANCE: according to the invention, non-contact power transmission device includes an electric power transmission unit, a first temperature sensor, a second temperature sensor, and an electronic control unit. First temperature sensor is configured to determine the temperature of the inverter. Second temperature sensor is configured to determine the temperature of the resonant circuit. Electronic control unit is configured to adjust the frequency by controlling the operation of the inverter. Electronic control unit is configured to perform the first control when the temperature of the inverter is higher than the temperature of the resonant circuit and also the second control when the temperature of the resonant circuit is higher than the temperature of the inverter. First control includes control for such frequency adjustment to reduce the inverter output current. Second control includes control for such frequency adjustment to reduce the current flowing through the resonant circuit.
EFFECT: technical result is an increase in the reliability of a non-contact power transmission device.
