Technical Article: Electronic Tap Switching Voltage Regulator

From Utility Systems Technologies, Inc.
 

 
The typical electronic tap switching voltage regulator works very much like the mechanical tap switching regulator - except that it replaces mechanical servo drives and brushes with solid-state semiconductor switches. Rather than using a motor to move brushes connected to the regulator output, the electronic voltage regulator will have taps on the secondary side of the transformer controlled (on or off) by semiconductor switches (like the silicon controlled rectifier - SCR).

Within the classification of electronic tap switching voltage regulator there are two distinct types: the full power semiconductor type, and the series transformer type. The full power semiconductor (FPS) type of electronic tap switching voltage regulator is most analogous to the servo tap switcher and is the most common type of electronic voltage regulator.
