QUESTION
A three-phase rectifier is required to supply a rms voltage of Vrms = 550 V at a ripple-free current of Irms = 2000 A. The rectifier is connected to the medium voltage supply via a Y-Y transformer
A three-phase rectifier is required to supply a rms voltage of Vrms = 550 V at a ripple-free current of Irms = 2000 A. The rectifier is connected to the medium voltage supply via a Y-Y transformer (a12 = 5:1).
3.2.1 Determine secondary line-to-line voltage (VLL) necessary to produce the required rms output voltage.
