Abstract:
      When the load of a rectifier circuit is the armature of a battery, its circuit operation and reactive power measurement will be different from those in the case of pure resistance load. In this paper, a graphical method for a single-phase phase-controlled rectifier circuit under back EMF load is proposed. A three-dimensional Lissajous diagram is drawn based on the waveforms of voltage and current on the grid side as well as the corresponding flux. In addition, the area of the projection triangle is used to analyze the reactive power flow. This method can be used to provide reference in measuring the reactive power and compensating the power of the single-phase phase-controlled rectifier circuit. The analysis results show that the proposed graphical method for reactive power under back EMF load is simple and intuitive, and has better real-time performance.
