The previous video introduced the principle of armature voltage control for a DC motor.  This video shows, using a SimPowerSystems file, how the armature voltage can be generated by the use of a 3 phase six pulse fully controlled rectifier.  By varying the firing angle (alpha) the average output dc voltage can be varied and this results in a speed change of the DC motor.
