要約(英語): This paper presents that the phase characteristics in the current waveform at using home electric appliances were found. A current waveform consisting of a right triangle pulse waveform over a particular voltage phase range was focused. Then, the phase characteristics of the harmonic current of this waveform were investigated. θS(p) = θp + 360・Np for the phase valueθp at each harmonic order p (p = 1, 3, 5, ..., 39) of the measured waveform were calculated. Np is the smallest integer greater than or equal to 0 that satisfies θS(1) < θS(3) < θS(5) < ... < θS(39). The relationship between θS(p) and the harmonic order p is almost linear. An approximate equation of the harmonic order could be obtained using values of θS(p)/p. The phase values for simulation were derived from the values obtained by this approximate equation. Consequently, analyzed current waveforms using these phase values reproduced the measuredcurrent waveforms.
