摘　　要：在工程应用中,电源质量的高低往往影响着用电设备的使用状态。目前,在国内外部分地区,电网质量较差,因此寻求一种能够将谐波含量高的交流电能转变为谐波含量较低的交流电能的装置迫在眉睫。本文通过对AC/AC直接变换技术的研究,借助MATLAB/Simulink平台,对目前正在研究的3种控制策略正弦脉宽脉位调制、以正弦波的绝对值作为调制波的调制方式以及基于d-q变换进行的双闭环控制进行了仿真。分别展示了输入电压不稳时,3种控制策略下输出的电压、电流波形。此外通过对比,论述了在不同控制策略下,其呈现的效果差异与优缺点。In engineering application,the quality of power supply often affects the normal use of electrical equipment.At present,in some parts of foreign countries,the quality of power grid is poor,so it is very important to find a device that can transform the AC energy of voltage with High harmonic content into AC energy of constant frequency and constant voltage.In this paper,through the research of AC/AC direct conversion technology,with the help of MATLAB/Simulink platform,three kinds of control strategies are studied:sinusoidal pulse width modulation,the absolute value of the sine wave as the modulation mode and the double closed-loop control based on d-q transformation are simulated.When the input voltage is unstable,the output voltage and current waveforms are shown respectively.Through comparison,the paper discusses the effect differences,advantages and disadvantages under different control strategies.
