基于恒压输出区间追踪的WPT系统抗偏移方法
Anti-offset Method for WPT System Based on Constant-voltage Output Interval Tracking
摘要
Abstract
An anti-offset method for a wireless power transmission(WPT)system based on constant-voltage output interval tracking is proposed to deal with the problem of output voltage fluctuation when the coupling mechanism in the WPT system is shifted.First,a model of a CLC-S WPT system is established,and the relationship between the mutual inductance and output voltage gain in resonant and non-resonant states of the system is analyzed.Based on the analysis,it is found that the system has a stronger anti-offset capability in the constant-voltage output interval when it works in the non-resonant state.Second,an inductance compensation sequence is designed,and a constant-voltage output interval tracking control strategy is proposed to realize the constant output voltage control of the WPT system and improve its anti-offset capability.Finally,a simulation model and a test platform were built,and simulation and experimental results show that the constant-voltage output interval tracking control strategy can effectively reduce the output voltage fluctuation,thus verifying the robustness of the system under strong mutual inductance interference.Compared with the WPT system without constant-voltage output interval tracking,the CLC-S WPT system has a better dynamic regulation capability of output voltage.关键词
