摘要

如果在绿色能源间歇性的情况下必须跟踪最大功率和效率，那么从不同来源收集能量是具有挑战性的。同时进行最大功率和效率点跟踪的研究是针对具有相当发电能力的单一电源。本文提出了一种低计算量算法，用于并行输入单输出升压型电子变换器在顺序触发、非对称输入和低功率源的DCM中同时进行最大功率和效率点跟踪。在数值模拟中，即使考虑噪声(有界但合理)和主要组件的寄生，也可以在很宽的工作条件下获得95%的稳定效率。

Simultaneous MPPT and MEPT for Asymmetric Parallel Boost-Type Converters

Energy harvesting from different sources is challenging if maximum power and efficiency must be tracked in green energy intermittency scenarios. Studies for simultaneous maximum power and efficiency points tracking are aimed at a single source of considerable power generation capability. This paper proposes a low computational burden algorithm for simultaneous maximum power and efficiency point tracking for a paralleled-input single-output boost-type electronic converter operating in DCM with sequential triggering, asymmetrical inputs, and low-power sources. In numerical simulations, a stable 95% of efficiency is gained over a wide range of operation conditions, even considering noise (bounded but reasonable) and parasitics of the main components.
