Abstract
It is an object of the present invention to provide a power supplying apparatus, a power receiving apparatus, an electrical vehicle, a charging system, and a charging method, the power feeding apparatus improving reliability by suppressing any decrease in charging efficiency and making charging control communication more resistant to high-frequency noise of a switching element. A power supplying apparatus for feeding power to an external apparatus, wherein the power supplying apparatus is characterized in having a power conversion unit, a power supplying unit, a control unit, and a communication unit. The power conversion unit includes a power conversion switching element capable of changing the a switching waveform of the switching element. The power supplying unit supplies power to the external apparatus, the power being generated in the power conversion unit. The communication unit communicates with the external apparatus. The control unit conducts a control so as to adjust the switching waveform of the switching element in the power conversion unit during a period in which the communication unit communicates with the external apparatus.
