Let’s start by setting up a simple circuit - HALF WAVE RECTIFIER
Click on components and place it in the work panel
Double click each element to change the values. Right-click to rotate an element.
Connect the elements by ‘wire’ tool.
Before starting simulation, select simulation control from simulate tab.
Place the clock at convenient portion in work panel
Specify the time step, total time and other requisite parameters.
Close simulation control window

Click “Run Simulation” or press F8
On running the simulation the SIMVIEW window will be opened automatically.
If it does not open automatically, click “Run Simview” from Simulation tab or press Alt+F8
Select parameter to be displayed (voltage in this case) to be displayed

CIRCUIT - 3
SIMULATION RESULTS
Note the difference in output. The wave is clipped at +3V. The minimum
of the wave is -6V which is due to the voltage divider action of two 1
ohm resistors

CIRCUIT – 6
Single phase half wave controller with R Load
Set Alpha (DC voltage) = 30V
Set alpha control (firing angle) to 30 degrees.
The firing angle block i.e. alpha controller is available from the elements
menu

SIMULATION RESULTS
Firing angle = 30 deg
The peak value of parameters are shown in the measure window
Firing angle = 90deg
Set Alpha (DC voltage) = 90V
Set alpha control (firing angle) to 90 degrees.

Firing angle = 120 deg
Set Alpha (DC voltage) = 120V
Set alpha control (firing angle) to 120 degrees.
