Abstract

In this work, a comparative analysis of the performance and efficiency of the FCS-MPC and Modulation FBQ applied to an AFE active front rectifier is carried out. The above compares quality indicators of form in the input current of an AFE, THD, and WTHD rectifier. For efficiency, the conduction and commutation losses in the switches will be estimated to obtain a selection criterion between these two control methods, which will be based on the efficiency of the converter and the performance of the input current loop. The semiconductors losses are calculated by linear mathematical approximations, which depend on the operation point of the AFE rectifier and the switch parameters, which are obtained from the datasheet provided by the switch manufacturer, which for this work, IGBT IKW25T120 was selected. Finally, for the performance analysis, satisfactory simulation results were obtained.

有限控制集模型预测控制和反馈量化器的AFE整流器的性能和效率比较

本文对FCS-MPC和调制FBQ应用于AFE有源前整流器的性能和效率进行了比较分析。以上比较了AFE、THD和WTHD整流器输入电流的质量指标。对于效率，将估算开关的导通和换流损耗，从而在这两种控制方法之间获得一个选择准则，该准则将基于变换器的效率和输入电流环的性能。通过线性数学近似计算半导体损耗，这取决于AFE整流器的工作点和开关参数，这些参数从开关制造商提供的数据表中获得，为此工作选择了IGBT IKW25T120。最后进行了性能分析，得到了满意的仿真结果。
