Abstract
(EN)
This wireless electrical power supply device 100 is characterized by being provided with: a first electrical power supply device 101; a second electrical power supply device 104; voltage control circuits 113, 123 that control a first voltage difference between a first input voltage E1 and a first output voltage E2 during normal-direction electrical power transmission and control a second voltage difference between a second input voltage E2 and a second output voltage E1 during reverse-direction electrical power transmission; second switching control circuits 121, 122 that, during normal-direction electrical power transmission, turn a second transistor Q2 off to allow rectification to be performed by a second diode D2; and first switching control circuits 111, 112 that, during reverse-direction electrical power transmission, turn a first transistor Q1 off to allow rectification to be performed by a first diode D1.
