Enhanced Power Transmission for On-road Agv Wireless Charging Systems Using a Current-optimized Technique

Year: 2019

Type: article

Abstract: This paper provides a sound wireless power transfer (WPT) recharging solution for onroad automated guided vehicle (AGV) system.In this solution, multiple transmitting coils serve as power transmitters (TXs), and a receiving coil in AGV serves as a power receiver (RX).The multiple TXs are along a straight track for dynamic charging to AGV.The circuit model of multiple-TX and single-RX WPT system is first constructed based on circuit theory (CT), and then current-optimized scheme based on Lagrangian multiplier method is proposed to tune the currents in multiple TXs to maximize the power delivered to the load (PDL).The equal current (EC Case) flowing through each TX is compared with the optimal current (OC Case).Through contrastive analysis, the OC Case shows its advantages in PDL.Finally, the theoretical analysis results are confirmed by the results of full-wave electromagnetic simulation.
