Source sentences:
text: The effective voltage can be varied by inserting a series resistor or by an electronically controlled switching device made of thyristors, transistors, or, formerly, mercury arc rectifiers.
text: A phase shift of the gates pulses allows the effective voltage, seen by the motor to be varied.
text: By varying the delay (the phase angle) before the current is turned on, the average current, and thus the average voltage seen by the load, can be varied as shown below.
