Abstract: PROBLEM TO BE SOLVED: To solve the problem of an unbalanced voltage unable to be be removed completely, because of not synchronizing the variation period of the unbalanced voltage with the integration period of an integrator circuit, resulting in the electrical energy involving the unbalanced power as error component being measured. SOLUTION: A zero-cross detector circuit 27 generates a zero-cross signal from a measured voltage V, a frequency divider circuit 28 divide the frequency of this signal, and a control signal generator circuit 29 generates control signals S1, S2 from the frequency-divided signal; the signals S1, S2 being for control current switches 25a, 25b for reversing the direction of a Hall current Ic, flowing in a Hall element 22 and an amplifier output switch 26 for reversing the polarity of a signal amplified by a differential amplifier circuit 23. An integrator circuit 24 integrates a signal output from the switch 26 in the period-units of the control signal S1 to output an integrated electrical energy. Thus the integration period of the integrator circuit 24 coincides with the variation period of an unbalanced voltage, and the unbalanced voltage is completely removed, to accurately measure the electrical energy.
