Power feeding apparatus, transporter and transport system

Abstract

In a power feeding apparatus having pickup coils L1 and L2, a rectifier circuit 4 and output terminals U and V, the relays R1 and R2 are connected between the output side terminals of the rectifier circuit 4 and the output terminals U and V. Whereas a protective circuit (switching control circuit) 6, which is connected to the pickup coils L1 and L2 and the relay coils r1 and r2 to obtain the electric power from the output side terminals of the rectifier circuit 4 in order to carry out ON/OFF control of the relays R1 and R2 corresponding to the voltage at the both ends of the pickup coils L1 and L2, is provide. The power feeding apparatus enables to prevent an overcurrent from flowing through a load, to prevent the circuit elements from being destroyed or burnt out due to an overcurrent generated in the pickup coils or an overvoltage generated in a resonance capacitor, to indicate an occurrence of an abnormality and to control the electric power supply by means of a remote control.
