Abstract

PURPOSE:To remove commutation harmonic waves by obtaining the moved average of detected signal inputs having harmonic waves due to commutation in a power converter at every frequencies of pulsating fundamental frequencies sequentially. CONSTITUTION:A waveform W1 indicates an original waveform, a wave form W2 indicates fundamental component, a waveform W3 indicates harmonic wave component of the difference of the waveform W2 of the fundamental component from the original waveform W1, and a waveform W4 indicates the output waveform of the moved average at every 60 deg. of the waveform W3 of the harmonic wave component. Thus, the smoothing operation can be performed by the moved average, the average values of the harmonic wave component between arbitrary waveforms of 60 deg. difference can be canceled between the upper half-waveform part and the lower half-waveform part, and the harmonic wave component can be thus removed.
