摘要

逆变器是一种将直流电压转换为交流电压或反之亦然的电力电子设备。在微网系统中采用同步逆变器连接相位误差最小的可再生能源。在高效输配电系统中，采用三相逆变器。逆变器的电子开关由控制器电路控制，控制器电路可以是两电平脉宽调制(PWM)、锁相环(PLL)控制器等。一个固定的参考直流电压和电流发生器用于稳定的输入输出电压和电流，以减少高谐波畸变。设计了一个LC低通滤波器，并利用MATLAB2014a对系统的输入输出进行了仿真。输入滤波器用于降低直流输入电源中的交流纹波分量，输出滤波器用于降低逆变器输出电源的高频谐波畸变，以保持IEEE标准的THD

Low Noise Inverter for Poly Phase Microgrid System

The inverter is a power electronics device which changes DC voltage to AC voltage or vice versa. The synchronous phase inverter is used in the microgrid system to connect the renewable energy sources of minimum phase error. For a high-efficiency power transmission and distribution system, a three-phase inverter is used. The electronic switches of the inverter are controlled by a controller circuit which can be a two-level pulse width modulation (PWM), phase lock loop (PLL) controller, etc. A fixed reference DC voltage and current generators are used for a stable input-output voltage and current to reduce the higher harmonic distortions. An LC lowpass filter has been designed and simulated for the input and output of the system by using MATLAB2014a. The input filter is utilized to reduce the AC ripple component in the DC input supply, and the output filter is used to reduce the higher frequency harmonic distortion from the inverter output supply to maintain the IEEE standard THD
