Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
The rectifier example shows a B6 diode bridge fed by a three-phase sinusoidal voltage, loaded by a DC current. DC capacitors start at ideal no-load voltage, thus making easier initial transient.
Simulate until T=0.1 s. Plot in separate windows:
uDC ... DC-voltage
iAC ... AC-currents 1..3
uAC ... AC-voltages 1..3 (distorted)
Try different load currents iDC = 0..approximately 500 A. You may watch losses (of the whole diode bridge) trying different diode parameters.
