小型移動ロボットへのATAC方式を用いた非接触給電におけるLCの設計

　Wireless power transfer is applied to small mobile robots. Since the fluctuation of the received voltage is a problem in wireless power transfer to the small mobile robots, the suppression of the fluctuation is focused. In the magnetic resonant coupling method, it is necessary to match the resonant frequency of the primary side with that of the secondary side. The high Q value in the resonator causes voltage fluctuation due to the changes in load and/or distance. To solve this problem, the automatic tuning assist circuit (ATAC) is adopted to automatically adjust the resonance frequency, and the ATAC suppress the voltage fluctuation. In this paper, we focus on the inductance and capacitance of the ATAC system for wireless power transfer to small mobile robots and design the wireless power transfer system.
