摘要：

For automatic guided vehicles with dynamic wireless power transfer (DWPT), the gap of the receiver is inevitable due to the variation of load. It can cause the system coils’ parameters (self-inductances and mutual inductance) to change, further affecting the stability of the system output. In order to realize a stable output of the DWPT system when the gap of the receiver is variable, a parameter design method based on a series-series (SS) topology is proposed in this paper. An equivalent circuit model of the SS topology considering the change of coil parameters is established to analyze the influence of the compensation parameters on system output. Thus, the constraints and solution space of compensation topology parameters are determined. A parameter design method for SS topology is proposed based on particle swarm optimization algorithm to maintain stable output current and high efficiency. Finally, a 1kW prototype was built to verify the effectiveness of the proposed approach. Experimental results indicate that within the gap range (20mm～80mm), the maximum fluctuation of the designed system output current is only 3.55% when the self-inductances increase by 19.1μH and 45.22μH, respectively, and the mutual inductance increase to 2.4 times. Furthermore, the highest efficiency of the system reaches 96.52%. © 2022 Chinese Machine Press. All rights reserved.
