摘要
针对逆变电源向各种负载提供高质量电能的需要,抑制谐波对各种用电设备的危害,通过分析单相桥式逆变电路结构特点,提出了将重复控制和模糊自整定PI控制相结合的新型单相SPWM逆变电源控制方案。并通过仿真实验对比可知采用新型复合控制器的系统具有很强的带不平衡负载能力,完全满足工业领域中频电源的要求,有广阔的应用前景。
A new single-phase SPWM inverter power supply control scheme combining repetitive control and fuzzy self-tuning PI control is proposed. The simulation experiment shows that the system with new composite controller has a strong unbalanced load capacity. See the text for details.
