Hey guys,
I need help in understanding the control loop of DC drives.I went through some articles on it but could fully comprehend reason behind controlling the current with a inner current loop, when ideally they should be controlling voltage.
The firing angle is varied to control the speed of motor , which is basically control of voltage not current.Does the drive convert current to voltage output ?
Can anyone direct me to a good technical write up .
