This paper proposes a contactless power supply system for automated guided vehicles (AGVs) with a topology of two receiving coils. The study features balanced dual output capability for charging motors of the front and the back wheel of AGVs simultaneously, and they can be charged while moving along the rail. The equivalent resonance circuit configuration is established and characteristics of mutual inductances are analyzed as well in order to determine the system parameters with a higher efficiency. The output voltages can be easily adjusted based on the resonance analysis of the proposed system, where the coupling effect as well as output voltages are stabilized during moving operations. Experimental results reveal that the voltages at dual outputs are suitable for charging motor batteries, confirming the practicality of the proposed method for the application that is considered.
