摘　　要：详细阐述了基于交-直-交拓扑的大功率电能质量信号发生装置设计方法,主要包括整流侧滤波电感、逆变侧输出滤波器和直流侧电容设计等;采用瞬时功率平衡原理,在含有谐波的情况下建立直流电压的精确数学模型,用于指导直流电容设计;研制了试验样机并进行实验研究。实验结果验证了设计参数和结论的正确性及有效性,所研制的样机能够实现单位功率因数整流,并能产生各种包括电压跌落、闪变、骤升、中断、凹陷、谐波等电能质量信号。A design method of AC-DC-AC based high-power power quality signal generator is presented and analyzed, mainly including the design of DC side capacitor, input and output filter. Mathematic module of DC voltage is established under the principle of simultaneous power balance and harmonics to guide the design of DC capacitor. A prototype has been realized and some experiments are carried out. The experiment results validate the circuit parameters and conclusion The implemented prototype can realize unit power factor rectifier function and can generate all kinds of power quality signals such as sag, flicker, swell, interruption, notch and harmonic.
