摘要和关键词

摘要: 感应耦合式无线电能传输(inductively coupled power transfer, ICPT)是利用中低频(10～1 000 kHz)电磁场的近场耦合实现电能的无线传输技术, 在线圈耦合机构中添加金属屏蔽层可以有效减少磁场泄露, 但对电场的屏蔽效果有限, 导致线圈周围存在漏电场, 当人体接触到耦合机构周围的导体时可能存在触电危险。文章首先建立用于分析漏电场感应电压问题的磁耦合机构等效电容模型, 并计算出人体接触磁耦合机构金属屏蔽层时的感应电压; 进而提出一种新型ICPT系统结构及其优化策略, 有效地将耦合机构附近金属导体的感应电压降低到安全标准以内; 最后通过ICPT系统样机实验, 验证了所建立模型的准确性与优化方法的有效性。

Abstract and Keywords

Abstract: Inductively coupled power transfer (ICPT) is a wireless transmission technology that utilizes near-field coupling of medium to low frequency (10-1 000 kHz) electromagnetic fields. Adding a metal shielding layer to the coil coupling mechanism can effectively reduce magnetic field leakage, but it cannot effectively shield the electric field, resulting in a leakage field around the coil. Therefore, there may be a risk of electric shock when the human body comes into contact with the conductors around the coupling mechanism. In this paper, an equivalent capacitance model of the magnetic coupling mechanism is first established to analyze the leakage field induced voltage, thereby calculating the induced voltage when the human body contacts the metal shielding layer of the magnetic coupling mechanism. Then, a new ICPT system structure and its optimization strategy are proposed, effectively lowering the induced voltage of the metal conductor near the coupling mechanism to comply with the safety standards. Finally, experiments were conducted on the ICPT system prototype to verify the accuracy of the established model and the effectiveness of the optimization method.

Keywords: inductively coupled power transfer (ICPT); equivalent capacitance model; induced voltage; safety issue
