滑模控制算法在在线式大功率UPS高频整流器中的应用
Application of Sliding-Mode Control Algorithm to the On-Line High-Power UPS High-Frequency Rectifier
摘要
Abstract
In view of the deficiencies of the traditional un-interruptible power supply charging , in this study the PWM rectifier was substituted forthe three circuit modules of rectification, charging and PFC in the traditional UPS, and by controlling the PWM rectifier, the three-stage charging mode was achieved. Meanwhile, in order to realize smooth switching in each charging stage, the current closed-loop sliding-mode control strategy was adopted, which was based on the synchronous rotating coordinate.Simulation results showed that this control strategy has a better DC charging voltage tracking capability with smooth response and strong robustness.关键词
