Study on Detection Method for Three-Phase Reactive Current Based on Analog Multiplexer |
|
| 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.In this paper,a novel detection method for three phase reactive current with analog multiplexer is studied.The operation principle of the three-phase reactive current detection is also presented and an available circuit is illustrated.The simulation study has been down for some typical power factor angle,the simulation result shows th... |
