摘　　要：介绍了基于现代电力电子技术的可连续运行的动态电压恢复器串联侧及并联侧工作原理、运行模式、硬件电路。通过仿真及实验证明,它可以有效地抑制电网中各种电压的干扰对负荷的影响,是解决电能质量问题的有效手段之一。As being plenty of nonlinear and impact toad, asymmetrical distribution network voltage caused by power network faults, as well as the flicker, fluctuation, harmonic, a tot of electric energy quality sensitive equipments can not be in the normal operation, which causes huge pecuniary toss. This paper introduces the working principle, operation pattern and hardware circuit of UDVR based on modern power electronic technology. The simulation and experiment of UDVR device show that it can be effective to restrain the influences of various voltage disturbance in power network on toad, and is the one of effective means of solving the quality problem of electric energy, to satisfy the power toad demand on quality of power supply. Along with the reduction of hardware cost, UDVR has extensive application prospect in power network.
