Enhanced Power Transmission for on-Road Agv Wireless Charging Systems Using a Current-Optimized Technique

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 multiplie… Show more

“…All the diameters and the turn numbers of TXs and RX are 31 cm and 25, respectively. We use a 1.2 mm diameter copper wire with electrical conductivity of 5.7×10 7 S/m to wind the power transmission coils, the selfinductance and parasitic resistance values of which are L T � L R � 40.55 μH and r T � r R � 1.96 Ω according to theoretic calculation [14,24]. e series capacitors of C T � C R � 625 pF are connected to coils to achieve the resonance frequency f 0 � 1 MHz (ω 0 � 6.28×10 6 rad/s).…”

“…e series capacitors of C T � C R � 625 pF are connected to coils to achieve the resonance frequency f 0 � 1 MHz (ω 0 � 6.28×10 6 rad/s). Figure 2 illustrates the model setup for a maximum of five TXs and a single-RX WPT system [14], which is also investigated in this paper. e parameters of D I , D M , and D T are the interval distance between TXs, the offset distance from RX to TX 3 , and the transmission distance between TXs and RX, respectively.…”

“…The dynamic performance and economic performance of AGV are important performance indexes. M. De Ryck put forward the energy management optimization scheme of AGV [3], and Jin Zhang proposed a wireless charging solution for AGV [4]. However, there are few researches on the dynamic performance and economic performance of AGV.…”
