Study on single-phase contactless power transfer system for AGVs

This paper studies on a single-phase contactless power transfer system for automatic guided vehicles (AGVs). This system consists of transmitter lines placed on a floor and a receiver coil installed in AGVs. The design of the cables and lines is described. The several arrangement of ferrite bars for the receiver coil are compared to obtain maximum mutual inductances between the transmitter lines and the receiver coil. The voltage supplied to the AGV is controlled at 24 V by the buck boost converter on the DC stage in the receiver. Numerical simulation results confirm the single-phase contactless power transfer system can perform effectively as a power supply system for AGVs.
