Abstract

Leakage current is one of the main issues for transformerless grid-connected photovoltaic inverters, and its reduction is a primary focus of various studies reported in the literature. This article proposes and validates a finite control set model predictive controller with a novel cost function to mitigate leakage current in a single-phase full-bridge (FB) grid-connected inverter with an LCL filter, making no modifications to the traditional FB topology and without adding any extra components. Furthermore, mathematical modeling is based on the fully actuated system model, allowing a reduction in the number of variables sensed during implementation, resulting in only grid current and voltage being measured.
基于预测控制代价函数的单相并网逆变器漏电流抑制及FAS模型
漏电流是无变压器并网光伏逆变器的主要问题之一,其降低是文献报道的各种研究的主要焦点。本文提出并验证了一种具有新颖成本函数的有限控制集模型预测控制器,以减轻带LCL滤波器的单相全桥(FB)并网逆变器中的漏电流,不修改传统的FB拓扑结构,也不增加任何额外的组件。此外,数学建模是基于完全驱动的系统模型,允许减少在实施过程中感知的变量数量,从而只测量电网电流和电压。
