传统的电能来源是污染的重要原因，并且正在迅速被可再生能源（RES）所取代。太阳能光伏发电系统是可再生能源的主要来源。在本章中，单相两级无变压器SPV逆变器系统已经建模和分析，使用MATLAB软件。第一级是一个闭环DC-DC升压转换器，用于调节太阳能电池阵列的DC输出电压。一个全桥逆变器，将直流电源转换成正弦交流电源形成第二级。该系统已在不同的负载和气候条件下进行了测试，可以将太阳能电池阵列的直流电压水平从（90-140 V）恢复到245 Vrms，50 Hz交流输出电压。建议的拓扑结构的设计，以满足一个典型的家庭具有2千瓦的额定效率提高，谐波减少，并优化使用选定的组件的要求。本章所做的整体工作的图形摘要已在图中描述。
The conventional sources of electrical energy are a significant cause of pollution and are being replaced by renewable energy sources (RESs) rapidly. Solar photovoltaic (SPV) system is the primary source among RESs. In this chapter, a single-phase two-stage transformerless SPV inverter system has been modeled and analyzed using MATLAB software. The first stage is a closed-loop DC-DC boost converter that regulates the solar arrays’ DC output voltage. A full-bridge inverter that converts the DC power to sinusoidal AC power forms the second stage. The system has been tested at varying load and climatic conditions and can restore the DC voltage level from (90–140 V) the solar arrays to the 245 Vrms, 50 Hz AC output voltage. The proposed topology has been designed to meet the requirements of a typical household having a 2-kW rating with improved efficiency, reduced harmonics, and optimal use of selected components. The graphical abstract for the holistic work done in the chapter has been depicted in Fig. .
