| 摘 要： | 该文介绍了一种宽度自适应的三电平电流滞环控制方法。在既保持电流滞环控制简单、电流响应快等特点的情况下,通过简单的算法,实现在三电平二极管中点箝位主回路拓扑结构上的准固定开关频率的电流滞环控制。降低了电流的总谐波畸变率,减小了转矩的脉动。并通过仿真验证分析结果。

| Abstract: | As for a width self adapting current hysteresis loop control of three-level PWM diode-clamped inverter, this paper presents a novel approach to achieve a quasi fixed switching frequency control, having the advantages of easy control and high current response of current hysteresis loop control, by using a simplified algorithm. Simulation results demonstrate this method could reduce current total distortion and torque fluctuation. |
