摘要
Delta逆变器是对交流电源全面进行补偿的新型逆变器，是串联、并联、串并联结构补偿电路的基础。串并联补偿式UPS是采用Delta逆变器的UPS，可以完善和提高系统供电的性能。通过对串并联补偿式UPS中Delta逆变器工作原理和功能分析，对于改进UPS设计有重要意义。
Delta inverter is a new inverter with full AC-power compensation function, and is the basis of series, parallel, and series-parallel compensation circuits. Series-parallel compensated online UPS improves the power supply system＇s performance based on Delta inverter. The analysis of working principle and function of Delta inverter in such a UPS, is significant for improving UPS design.
