Abstract :
Analogue multiplier has been widely used in the detection circuit of the reactive power. But an analogue multiplier is quite expensive so it is limited in some application case. And many analogue multipliers used in a circuit will reduce the detection accuracy. In this paper, a new method is proposed for detecting three-phase reactive current with analog multiplexer. The operation principle is presented. And an available circuit and it´s simulation results are illustrated. The simulation results show that it is feasible.
