一种双初级线圈并绕的感应电能传输系统及其功率分配方法
Dual Parallel Wound Primary Coils Based IPT Systems and Its Power Allocation Technique
摘要
Abstract
The power capacity of the single-phase H-bridge inverter and single primary coil used in the traditional inductive power transfer (IPT) systems is limited by the constraint of the power electronic devices,so that it may not be able to meet the high-power requirement of rail transit applications. A novel IPT system with dual parallel wound primary coils is proposed in this paper to enhance the system’s power capacity, and each primary coil is equipped with a high-frequency inverter. After analyzing the circuit topology of this proposed structure by coupling model in detailed, it is released that this structure not only needs capacitors to compensate the coil’s self-induction, but also needs additional capacitors to compensate the equivalent reactance caused by another primary coil. By choosing appropriate additional compensation capacitances, effective output power allocation of two inverters is achieved. Finally, an experimental setup of total power output of 1.4 kW is employed to verify the output power ratio of 1:1 and 1:2. The result shows that the proposed system is validated.The IPT system based on dual parallel wound primary coil is prospected to be applied in the rail transit contactless power supply system.关键词
