Abstract
To address the problems of poor power supply stability and high dependence on the traditional power grid for low-power terminals in rail transit, this paper proposes a piezoelectric-triboelectric hybrid power generation and low-power power management system. A 3×3 array structure is adopted to synchronously collect mechanical energy, and energy regulation is realized by a rectifier boost circuit with ADP5091 as the main controller and a variable-step MPPT control strategy. Verified by multi-physics simulation, circuit simulation and field measurement, the output performance of the hybrid generator is significantly better than that of a single structure, and the system can achieve a self-powered ratio of 86.2% for low-power equipment. The proposed system realizes the collaborative innovation of structural integration, low power consumption and high efficiency, with strong engineering practicability and scene promotion value. The scheme features compact structure and low power consumption, which can provide a reliable reference for the design of passive intelligent equipment in transportation.
