POWER RECEPTION DEVICE AND NON-CONTACT POWER TRANSMISSION SYSTEM
DRIVE
March 28, 2024
A power reception device includes: a power reception coil that receives power transmitted from a power transmission coil in a non-contact manner; and a control device that executes a short-circuit mode in which a plurality of switching elements provided between the power reception coil and a load are caused to perform switching operations to short-circuit between output terminals of the power reception coil. Further, when a phase of a current and a phase of a voltage in the power reception device are deviated from each other, the control device sets switching timings of the switching elements to the short-circuit mode in a manner that the phase of the voltage is shifted in a direction in which a power factor of power supplied to the load is deteriorated.
