Abstract

This paper presents the development, analysis and testing of a dynamic model for a boost converter powered by a photovoltaic panel. The mathematical model of the panel is presented and a strategy is proposed to integrate its nonlinear dynamics into the dynamic model of the boost converter. Emphasis is placed on the dynamic behavior, leaving the modeling of the effects of parasitic losses inherent to electronic devices for a future study. A discrete model that is feasible to implement in an FPGA to achieve HIL simulation in real time is shown. An optimized strategy of implementation of nonlinear functions implemented in lookup tables is presented. That strategy allows optimizing the resolution without affecting the calculation latency. A latency analysis of the calculation of the model states is also included where a time of 100ns is established for each simulation step. This latency time is sufficient for real-time simulations. Finally, comparisons of results with a software-based simulator to validates the proposed model are shown.

低成本、优化的 FPGA-HIL 实时仿真光伏电池板供电的升压转换器

本文介绍了由光伏电池板供电的升压转换器动态模型的开发、分析和测试。文中介绍了光伏板的数学模型，并提出了将其非线性动态特性纳入升压转换器动态模型的策略。重点放在动态行为上，对电子设备固有寄生损耗影响的建模留待今后研究。图中展示了一个离散模型，该模型可以在 FPGA 中实现实时 HIL 仿真。介绍了在查找表中实现非线性函数的优化实施策略。该策略可在不影响计算延迟的情况下优化分辨率。此外，还对模型状态计算的延迟时间进行了分析，确定每个模拟步骤的延迟时间为 100ns。这一延迟时间足以满足实时模拟的要求。最后，还展示了与软件模拟器的结果比较，以验证所提出的模型。
