The concept of a limit cycling control in power supplies |
|
and speed control has advanced the application of these |
|
broad |
|
areas. ON-OFF switching of a thyristor provides a simple |
|
and |
|
economical method of control and regulation. This |
|
switching |
|
of the thyristor causes the system to limit cycle. |
|
Basic analysis and design of speed control was performed |
|
A describing function was developed to model the power- |
|
supply |
|
and rectifier bridge. Then it was used to predict the |
|
frequency |
|
and amplitude of the limit-cycle. |
|
A digital computer program was used to simulate the system |
|
response and to construct the describing function curves. |
|
To verify the describing function validity, the limit |
|
cycle |
|
predictions were compared with the simulated results. |
|
Fourier analyses were performed to determine the ripple |
|
instability and subharmonic effect of the system output. |
