摘要

提出了一种用于摩擦电(TE)能量收集(EH)系统的双向高压(HV)双输入(DI)降压转换器和完全集成的最大功率点(MPP)跟踪器。所提出的MPP跟踪器采用分数开路电压(FOCV)方法，无需任何外部电阻进行降压转换。所提出的降压变换器调节来自摩擦纳米发电机(TENG)的两个高达70 V的高直流电压，具有单个共享电感。通过减小交换节点电容，提高了功率转换效率，最大端到端效率为70.72%，比前人提高了21.15%。

A Bidirectional High-Voltage Dual-Input Buck Converter for Triboelectric Energy-Harvesting Interface Achieving 70.72% End-to-End Efficiency

A bidirectional high-voltage (HV) dual-input (DI) buck converter and a fully integrated maximum power point (MPP) tracker for a triboelectric (TE) energy-harvesting (EH) system are proposed. The proposed MPP tracker carries out the fractional open-circuit voltage (FOCV) method without any external resistor for voltage down conversion. The proposed buck converter regulates two high DC voltages from a triboelectric nanogenerator (TENG) up to 70 V with a single shared inductor. By reducing the capacitance at the switching node, the power conversion efficiency is improved, and the maximum end-to-end efficiency is 70.72%, which is 21.15% higher than prior work.
