摘要
通过分析SPWM逆变器的谐波成分和来源,建立了一种更接近实际的逆变器控制模型,提出了运用有源高通滤波器进行局部反馈控制,消除输出平均值反馈型正弦波逆变器谐波的逆变电源设计方法,并运用乃奎斯特稳定判据分析了系统的稳定性,得出设计参数,利用该方法可以有效地解决输出平均值反馈型正弦波逆变器在非线性负载条件下输出电压波形的失真问题,从而在发挥输出平均值反馈型正弦波逆变器的优势的同时,扩大了其应用范围。之后,利用MATLAB进行了仿真,制作了实验电路,仿真和实验结果进一步证明了该理论的正确性以及该方法的合理性。
This paper given an actual inverter control model by analyzing the harmonic of the SPWM inverters, and a novel design method that reduced harmonic of average output voltage feedback SPWM inverters was given by high-passed filter part-feedback loop ,the stability was analyzed by Nyquist stable criterion, the design parameter was obtained, used this method could resolve the waveform distortion problems of average output voltage feedback SPWM inverters in the non-linear load conditions, and extended it＇s applying scale. The simulation and experiment result prove that the method is available.
