摘要
提出并分析了一种用于UPS中单相电压源逆变器的新的控制策略———引入电压微分反馈代替传统的输出滤波电容电流反馈。该控制方法除了具有闭环反馈控制方法的特点外 ,还具有输出波形质量好、动态响应速度快的优点。这些优点在 5kVAUPS实验样机中得到了很好的验证 。
This paper introduces and analyzes a new control strategy with capacitor voltage differential feedback for the single phase voltage source UPS inverter .In this control scheme,only the capacitor voltage needs to be sensed as a control variable.Except for the basic features of feedback control strategy,the scheme offers many features that are attractive to the UPS applications such as lower harmonics component and fast dynamic response.A 5kVA UPS system under the proposed control scheme is provided to verify all of these features.
