摘要

针对现有无源物联网能量采集方案存在单频段射频适配性差、多能量源整合效率低、阻抗匹配设计不精准，且单一供能模式受环境影响大、能量输出稳定性不足等问题，设计了一款集成最大功率点跟踪(Maximum Power Point Tracking

MPPT)的射频能-太阳能混合环境能量收集电路。针对传统结构普遍存在的电压低，高插入损耗的缺点，提出了改进传统倍压结构，采用单端接地级联输出方式，实现多支路射频电压高效直流叠加，实现接近14.8V的开路电压和0dBm输入时1.363mW的最佳输出功率，相对于传统结构开路电压提升近四倍，最佳输出功率提升约7.5%，带载能力也有显著提升。同时，以BQ25504为核心设计双输入能量管理电路，针对太阳能与射频能MPPT系数的差异，采用两路独立MPPT适配+二极管防倒灌结构，实现双能量源独立最大功率跟踪与协同供电，保障能量稳定输出。

Abstract

To solve the problems existing in conventional passive Internet of Things energy harvesting schemes

including poor adaptability of single-band RF energy harvesting

low efficiency of multi-source integration

inaccurate impedance matching

and unstable output under variable environments

a dual-channel RF–solar hybrid energy harvesting circuit with Maximum Power Point Tracking (MPPT) was proposed in this paper. An improved voltage multiplier with single-ended grounded cascaded output was designed to realize efficient DC stacking of RF voltages. An open-circuit voltage of nearly 14.8 V and a maximum output power of 1.363 mW were achieved at 0 dBm input power. Compared with traditional structures

the open-circuit voltage was increased nearly fourfold

and the output power was improved by approximately 7.5%. A dual-input energy management module based on BQ25504 was adopted

in which independent MPPT control was implemented for RF and solar inputs with diode reverse-current protection. Coordinated operation and stable energy output are realized in the whole system.
