Part 2 - Three-phase Diode Bridge Rectifier - Inductive Load
Page Content
Exercise 3: Varying Inductive Load
In the panel, choose under Pre-Selected: Single Phase: Varying Inductive Load without smoothing capacitor.
Now, the resistance (R) is in series with an inductance (L).
Figure 18: Three-Phase Diode Bridge Rectifier Panel with an Inductive Load (R=25 ohms, L=40 mH)
Default Parameters
- AC Source Voltage : Ve= 120 V
- Frequency: 60 Hz
- R= 25 Ω, L=40 mH
Complete the following table with the many values of inductance (L).
L (H) | 40m | 100m | 1 |
|---|---|---|---|
The maximum peak value of the current (A) | |||
The minimum peak value of the current (A) | |||
THD of AC-source current (%) |
Table 14: Impact of Varying Inductive Load
Calculate the average current.
What is the effect of the inductance on the load current?
What is the effect of increasing the inductance on the THD of the AC-source current?
