摘要：通过介绍Delta逆变技术的主电路结构和控制方法等相关内容，提出了一种基于Delta逆变技术的不间断动态电压恢复器(UDVR)的系统结构，并详细分析了其控制策略和补偿原理。仿真结果表明，Delta系统可以有效地对电网电压进行动态补偿，使负载获得纯净的正弦输入电压，能满足电力负荷对供电质量日益提高的要求。

Abstract: The main circuit, control methods and related technologies of Delta inverter were introduced. Based on the research of Delta inverter, the system configuration of uninterruptible dynamic voltage restorer (UDVR) was presented, and its control strategy was analyzed in detail. Simulation results show that the UDVR could provide the loads a pure and standard sine voltage wave and satisfy the improved demand of loads to power quality.
Key words: Delta conversion technology; uninterrupted dynamic voltage restorer (UDVR); power quality compensation
