摘要

单相并网光伏逆变器通常用于将电力反馈给公用事业。本研究旨在探讨一种可替代的光伏逆变器拓扑方法，该方法在光伏并网应用的直流链路上使用电池。光伏组件的输出连接到DC/DC同步升压变换器，以提高系统电压，并从光伏阵列获得最大可用功率。采用PWM调制的单相半桥逆变器，在低通LC滤波器后产生正弦输出并网。讨论了其工作原理、性能和设计限制。仿真结果表明了该方法对光伏并网系统的适用性。

Implementation of a Single-Phase Half-Bridge Grid-Connected PV Inverter

Single-phase grid-connected photovoltaic inverters are commonly used to feed power back to the utility. This study aims to investigate an alternative photovoltaic inverter topology approach with a battery at the DC link for grid-connected photovoltaic applications. The output of the PV modules is connected to the DC/DC synchronous boost converter to increase the system voltage and obtain the maximum available power from the PV arrays. A PWM modulated single-phase half-bridge inverter is used to create a sinusoidal output for grid connection after a low-pass LC filter. Principles of operation, performance and design limitations are discussed. The simulation results show the suitability of the proposed solution for a grid-connected photovoltaic system.
