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 novel detection method for three-phase reactive current with analog multiplexer is proposed. The operation principle and simulation results are also presented. An available circuit is illustrated. The simulation result shows that it is feasible
