Simulation Using C

A C-program called, ss_resp.cpp, can be downloaded by clicking on the image below. It can be compiled as a C program and executed.

The program was run with the following values:
Time constant of the Link inductor in radians: 1.00
Time constant of the Source Inductance in radians : 0.03
Firing Angle = 30o.

The results obtained are presented below.

Another C-program called, harm3ph.cpp, can be downloaded by clicking on the image below. It can be compiled as a C program and executed.

The results obtained for the same parameters are presented below.
