提出了一种新的PWM逆变器实时数字反馈控制方法，实现了电压波动补偿的瞬时值控制。在该方案中，逆变器的采样频率变为载频的一半，适用于较高载频的实现。本文对不同LC滤波元件的逆变器输出特性进行了评价。验证了电容电流反馈信号对输出特性的影响。从UPS应用的角度出发，通过仿真和实验讨论了其优缺点，验证了所提出的控制律的优越性。
A new approach for real time digital feedback control of PWM inverter is proposed, in which an instantaneous value control with voltage variation compensation is achieved. In this scheme, the sampling frequency of the inverter becomes half of the carrier frequency, and it is suitable to implement for higher carrier frequency. In this paper, the output characteristics of the inverter for various LC filter components are evaluated. Also the influence of the capacitor current feedback signal for the output characteristics are verified. From the view point of UPS applications, the advantages and disadvantages are discussed though simulations and experiments, the superiority of the proposed control law is verified.
