Abstract: PURPOSE:To detect a phase of digitally from a three-phase sine wave which varies in waveform and crest value by providing two multipliers which perform multiplication by specific constants at each momentary point of the three-phase alternating current. CONSTITUTION:Respective pieces of phase information on three-phase alternating currents U, V, and W are inputted to the 1st and the 2nd processing circuits 100 and 101, and multiplied by constants k1-k3, and k4-k6 respectively. Those multiplication results are summed up by adders 7 and 8 respectively. The adders 7 and 8 perform specific calculations and their outputs are divided by a computing element 102 as specified and supplied to an A/D converter 103. A multiplier 104 find a phase from the digital conversion value from the A/D converter 103. Thus, the phase is detected digitally from the three-phase sine wave which varies in waveform and crest value.
