摘要：

The wired power supply method used in the coal mine safety monitoring system (CMSMS) sensor has potential safety hazards, and an alternative power supply method is required. In order to ensure the reliability of the power supply system, a new type of compact PCB resonator is proposed in this paper. The idea of this work is, First, the compensation inductor of the inductive power transfer (IPT) system using LCL-LCL topology is integrated with the power coil. The introduction of the DDQ coil structure to construct a double-coupled LCL topology improves the energy transfer density; Secondly, a four-layer PCB resonator that does not require additional compensation capacitors is constructed, which reduces the system volume and ensures reliability; Finally, the proposed work gives the design and optimization method of the coil parameters, and build the experimental prototype, which owns the 1.08 MHz working frequency. The charging current and voltage are 350 mA and 24.5 V, respectively. Simulation and experiments verify the feasibility of the proposed PCB resonator for sensor battery charging. © 2017 CPSS.
