摘要

本研究结合光伏阵列和直流-交流逆变器的设计，对3kW输出功率的光伏逆变器进行了完整的分析;本设计包括一个PV模块配置一个与逆变器功率输出相匹配的大阵列，DC-DC升压(boost)变换器，然后全桥利用MOSFET开关控制PWM (Pulse Width modulation)，利用LCL滤波器产生三电平信号并进行输出设计，最后给负载。研究了影响逆变器损耗和效率的逆变器参数。通过Matlab-Simulink仿真验证了设计的正确性，采用了真实的光伏组件、开关和无源元件的参数，使设计更接近实际工作。仿真结果证明了设计输出的一致性。

Design and Simulation of single-phase 3 kW PV inverter

This research provides a complete analysis of photovoltaic (PV) inverter of 3kW output power by merging the design of PV array and DC-AC inverter; The design includes a PV module to configure a large array that agrees with the inverter power output, the DC-DC step-up (boost) converter, next the full-bridge using MOSFET switches controlled by PWM (Pulse Width modulation) is used to generate three levels signal and the output LCL filter design, then to the load. Also studying the inverter parameters that affect the losses and inverter efficiency. The design is verified using Matlab-Simulink simulation using parameters of a real PV module, switches and passive elements to be close to practical work. The simulation results prove the design output consistency.
