Abstract
A wireless electrical power supply apparatusincludes a first electrical power supply unit, a second electrical power supply unit, voltage control circuitsandconfigured to control a first voltage difference between a first input voltage Eand a first output voltage Eduring forward power transmission and a second voltage difference between a second input voltage Eand a second output voltage Eduring reverse power transmission, a second switching control circuitconfigured to turn off a second transistor Qduring the forward power transmission and thereby cause a second diode Dto perform rectification, and a first switching control circuitconfigured to turn off a first transistor Qduring the reverse power transmission and thereby cause a first diode Dto perform rectification.
