水下自主航行器非接触式充电系统补偿电路设计

水下自主航行器非接触式充电系统采用分离式结构，其耦合系数低，功率因数小，系统的传输能力弱，因此需采用补偿电路使系统的功率因数达到最大，实现电能的高效传输。在深海环境下，系统初、次级磁芯在受到水流冲击后会产生偏心和间隙，引起耦合系数发生变化，系统的功率因数降低，传输能力同样受到影响。因此研究了水流冲击对各种补偿电路性能的影响，提出了AUV非接触式充电系统补偿电路的一般设计方法。

Circuit Design of Compensation for Contactless Power System of AUV

Owing to the separate structure, low coupling coefficient and limited power factor of the contactless power system of AUV, it is necessary to apply compensation circuits for maximizing power factor and increasing the efficiency of power transmission. In deep sea, the magnetic core of this system would deviate with the impact of water flow, on which condition the coupling coefficient may change, power factor of system decreases and power transmission is affected. This paper discusses the i MPacts of water flow to various compensation circuits, and proposes the common method of designing the compensation circuit for contactless underwater power system of AUV.
