Kd. Wu et Hl. Jou, A NEW PEAK DETECTION METHOD FOR THE 3-PHASE SINUSOIDAL SIGNALS, IEEE transactions on industrial electronics, 45(4), 1998, pp. 579-584
An instantaneous amplitude detection method for the three-phase sinuso
idal signals is proposed. The proposed method can measure the amplitud
e of the three-phase signals without any delay by using only two of th
e three-phase signals. The performance of this method under the ideal
and nonideal conditions is analyzed. To demonstrate the performance of
the proposed method, an electronic circuit for implementing this meth
od is developed and tested.
