Abstract In this thesis, full analytical and experimental investigation of current and power components produced in single-and three-phase, fully-controlled rectifier bridges is carried out, for both the supply and load sides. Analytical expressions of current and power components of the supply and load sides are derived, for the single-and three-phase, fully- controlled rectifier bridges when fed from an ideal supply. The deivation is extended to include, in addition to the supply and load sides, the terminal input voltage of the bridge for the case of the single-phase, fully-controlled rectifier bridge fed from a nonideal supply. Also, in this thesis, methods for obtaining the supply power factor corresponding to the nonsinusoidal currents drawn from the supply of the bridges considered have been investigated. This has been accomplished for several loading conditions and design and analysis of the compensation circuits, which are required to give maximum power factor for certain operating conditions, are presented. Experimental results are obtained to validate some of the theoretical results of the thesis. |
