Harmonic Suppression of High-Power UPS in Power Network

Lv Changzhi, Geng Anran, and Pan Jiaxing
Abstract—Rectifier is a necessary part of high-power UPS. But due to its nonlinear characteristics, serious input current harmonic pollution will be produced to the power network. In this paper, by theoretical analysis, calculation and simulation, the necessity of input current harmonic suppression of high-power UPS rectifier is proved. Sseveral harmonic control methods of input current are proposed according to two aspects: adding harmonic compensation device and improving rectifier architecture. Finally, by on-line test and parameter comparison, the feasibility of the scheme is verified.

Index Terms—High-power UPS, rectifier, input current, harmonic.
