PROBLEM TO BE SOLVED: To provide a power supply device, charger, and power supply system, capable of taking interruption measures during non-contact charging.SOLUTION: The power supply device 3 receives a pilot signal superposed over a charging AC power continuously transmitted from a charger 7 during charging using a primary coil 401 for transmission used for non-contact charging. Furthermore, the power supply device, when a reception level of the pilot signal received during charging is lower than a predetermined reference level, determines it to have no received pilot signal to stop an output of charging AC power. |
