Coursera 课程总结：单相无变压器逆变器使用 MATLAB 本课程深入探讨了电力电子领域，重点关注无变压器单相逆变器在可再生能源并网中的应用。随着电力电子技术的不断发展，高效的电力转换器已成为满足各种应用需求以及整合可再生能源进入电网的关键技术。 课程将重点介绍近年来涌现的多种单相无变压器逆变器拓扑结构，这些拓扑结构旨在有效降低漏电流。主要根据漏电流的抑制方法进行分类：带共模电压（CMV）钳位和不带CMV钳位的技术。具体而言，课程将讲解如何通过在全桥（H4）逆变器拓扑的交流侧或直流侧增加额外的开关，实现交流或直流解耦，从而获得电气隔离。 您将有机会学习和模拟10种不同的无变压器逆变器拓扑，包括H5、HERIC、H6以及改进型H6拓扑。所有这些拓扑设计都实现了单级功率转换。此外，课程还将教授正弦脉冲宽度调制（SPWM）策略，以实现高效的逆变器控制。
The power electronics field has matured over the last sixty years. Today, static converters can efficiently transform electric energy to meet the requirements of many applications. And are the enabling technology for the integration of renewable generation into the electric grid. So power electronics will play a key role in the renovation of the existing electric network.Many single phase transformerless inverter topologies with reduced leakage current have been introduced for grid tied photovoltaic (PV) applications in the past few years. These topologies are mainly classified on the basis of leakage current reduction methods: galvanic isolation with common mode voltage(CMV) clamping and without CMV clamping. The galvanic isolation can be achieved by incorporation of extra switches either on ac side or dc side of full bridge (H4) inverter topology for ac or dc decoupling respectively.So you all are going to learn simulation of 10 different transformerless inverter topologies such as H5, HERIC , H6 and improved H6 topologies. All the topologies are designed for single stage conversion apart from that you will learn sinusoidal pulse width modulation strategies (SPWM)
