The program focuses on the development of miniature energy harvesting accumulators used in automotive wireless tire pressure detection systems (TPMS). Working principle for the energy acquisition, conversion process power control technology. Will be based on the micro-hunting device energy generation range and output changes to do a specific discussion, due to the acquisition of energy is very small situation, the boost converter or regulator power loss should be minimized, so the power conversion Circuit research, we will first use the input energy storage circuit analysis and design to build low-loss conversion circuit, followed by this small hunting device energy conversion characteristics of the development of dynamic adaptive control strategy for the above do circuit matching research, and put forward Efficient switching circuit architecture and a wide range of voltage range control strategies in a variety of operating modes, while the circuit management in the system energy transfer to reduce the application of circuit power loss, to achieve the maximum efficiency of energy collection as the goal. Expect the next plan to design the IC chip with the relevant concepts to miniaturize the circuit and reduce energy consumption.”
