Summary:鉴于传统不间断电源充电环节存在的不足，本研究采用PWM整流器取代传统UPS中的整流、充电以及PFC三个电路模块，并通过对PWM整流器的控制来实现三段式充电的充电方式，同时为了实现各充电阶段的平滑切换，采用基于同步旋转坐标系下的电流闭环滑模控制策略。仿真结果表明，该控制策略具有较好的直流侧充电电压跟踪能力，且响应平滑，鲁棒性强。

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.
