近年来，多级逆变器被广泛应用于并网系统中，以减小滤波元件的体积，降低输出电压和电流的谐波畸变。在这些系统中，逆变器控制普遍采用传统的PI控制，在FRT条件下需要考虑其动态性能。本文提出了一种基于PWM保持技术的多级逆变器无差拍控制方法。研究了三电平逆变器在FRT条件下的快速瞬态响应。采用1MHz多采样方法提高动态响应。仿真结果验证了该方法的优越性。
Recently, multi-level inverters were widely applied to grid connect system to downsize the filter component and reduce the harmonic distortions of the output voltage and the current. In these systems, the conventional PI control is widely used for the inverter control, and the dynamic performance should be considered in the case of FRT conditions. In this paper, a new deadbeat control method for multi-level inverters is proposed based on PWM hold technique. Three level inverters are investigated to achieve the fast transient response in the FRT conditions. 1MHz multisampling method was also applied to improve the dynamic response. The advantages of the proposed method was verified through simulations.
