On The Energization and Steady-State Performance of 6-Pulse Diode Bridge Rectifiers Supplying Constant Voltage Loads

  1. Mohamed Mostafa Saied

Abstract

The paper addresses the analysis of 3-phase 6-pule diode bridge rectifier circuits supplying a special load category representable by constant voltage sources. The applied Mathematica-based solution technique can handle symmetrical and unsymmetrical 3-phase voltages. The presented results include the phase currents on the AC side as well as the magnitude and wave shape of the output current on the DC side.  Several case studies demonstrating the impact of the source’s operating frequency, its phase voltages’ degree of asymmetry as well as its internal reactance are presented.
