| 152 | <p>The rectifier example shows a B6 diode bridge fed by a three phase sinusoidal voltage, loaded by a DC current.
|
|---|
| 153 | DC capacitors start at ideal no-load voltage, thus making easier initial transient.</p>
|
|---|
| 154 | <p>Simulate until T=0.1 s. Plot in separate windows:
|
|---|
| 155 | <br>uDC ... DC-voltage
|
|---|
| 156 | <br>iAC ... AC-currents 1..3
|
|---|
| 157 | <br>uAC ... AC-voltages 1..3 (distorted)
|
|---|
| 158 | <br>Try different load currents iDC = 0..approximately 500 A. You may watch losses (of the whole diode bridge) trying different diode parameters.</p>
