摘　　要：提出了一种逆变器双环控制技术,该方案内环为单周期控制,外环采用K系数法设计的补偿器。仿真结果证明了该控制策略最显著的优点是:对输入电压的大扰动具有很好抑制性、负载变化时具有鲁棒性以及带非线性负载时高品质的输出波形。This paper presents a double-loop control of inverters. The inner-loop of this scheme is One-cycle Control and the outer-loop is the compensator designed by the K factor. Simulation results prove that the prominent performances of the control strategy are effective suppression of large line disturbances, robustness against load variations and good quality of the output voltage when supplying nonlinear loads.
