摘要：
Recently, as a convenient charging method for small IoT sensors, a magnetic resonant wireless power transfer (WPT) system is attractive. In WPT systems, robustness of the efficiency due to the position gap of the receiver and transmitter is very important. In this paper, we propose a method that reduces the efficiency decrease even if a position is displaced by using a Helmholtz coil structure. Comparison with general single coil WPT system is discussed in the evaluation about the efficiency.
