The recent introduction of high current-capacity |
|
thyristors has |
|
advanced the status of solid-state power supplies. ON-OFF |
|
switching of |
|
an entire rectifier bridge, rather than individual |
|
thyristors, provides |
|
a simple and economical method of control and regulation. |
|
This control |
|
philosophy causes the system to limit cycle. A describing |
|
function is developed to model the power-supply input |
|
transformer and rectifier bridge. The describing function |
|
is then used |
|
to predict the frequency and amplitude of the limit cycle. |
|
A digital computer program is used to construct the |
|
describing |
|
function curves, and to simulate the dynamic response of |
|
the system. |
|
Limit cycle predictions are compared with the simulated |
|
response to |
|
verify the describing function validity. |
