Abstract
This disclosure provides a wireless power transfer terminal that enables a power device to be used for both power transmission and power reception and allows space savings of circuits and a reduction in the cost of manufacturing. The wireless power transfer terminal includes first through fourth switching elements, a coil, and a control circuit. Each of two sets of switching elements forms a series circuit, and the two sets are connected in parallel to each other. The coil is connected between connection points of the switching elements of the series circuits. The control circuit performs switching control of the first to fourth switching elements in a power transmission mode and in a power reception mode.
