摘　　要：实际工程中逆变器滤波电路具有电感特性,且系统负载具有非线性特征,从而引起不间断电源系统输出发生畸形。为了提高输出电压波形的动态响应,以单相全桥逆变器为对象,建立了逆变电路与滤波输出电路模型,将无差拍控制与重复控制同时引入对逆变器的控制过程,形成复合控制系统,通过仿真发现系统具有良好的动态跟踪性能。In practical engineering,the inverter filter circuit has inductance characteristics,and the system load has nonlinear characteristics,which causes the output of the uninterruptible power supply system to be deformed.In order to improve the dynamic response of the output voltage waveform,the single-phase full-bridge inverter was taken as the object,the inverter circuit and the filter output circuit model were established,the deadbeat control and repetitive control were introduced into the control process of the inverter at the same time,and a composite control system was formed.The simulation result shows that the system has good dynamic tracking performance.
