This paper reports the design and its analysis of various filters used for signal separation for the induction machine drive system with high frequency voltage signal injection. The designed filters are notch filter in addition to 1st, 2nd, and 4th order low-pass filters. For the analysis method, the simulation is carried out by constructing an indirect type vector control system. Also, the stability analysis is carried out for the current controller with the filter. As the results, it is clarified that the fundamental component and the high frequency amplitude can be accurately extracted by using notch filter as compared with other low-pass filters.
