Title: CONTACTLESS POWER RECEPTION DEVICE, CONTACTLESS POWER TRANSMISSION DEVICE, AND CONTACTLESS POWER TRANSMISSION/RECEPTION DEVICE
Abstract:
A contactless power reception device is provided with: a power reception coil which receives electric power from a contactless power transmission device; a rectification circuit which rectifies the electric power received by the power reception coil, and which forms a high potential-side rectified output and a low potential-side rectified output; a smoothing circuit to which the high potential-side rectified output and the low potential-side rectified output are supplied; and a switching power supply which converts a direct-current voltage from the smoothing circuit into a first voltage. The smoothing circuit is provided with: a first inductor which transmits the high potential-side rectified output; a second inductor which transmits the low potential-side rectified output; and a smoothing capacitance element to which the transmitted high potential-side rectified output and the transmitted low potential-side rectified output are supplied. The low potential-side rectified output is connected to ground potential.
