Zener Diode Voltage Regulator Circuit: Regulator Circuit With No Load - The most important application of Zener Diode Voltage Regulator Circuit is dc voltage regulator circuits. These can be the…
Power Factor Improvement Methods: There are many drives which operate at a low power factor. Some of Power Factor Improvement Methods are: An induction motor direct on line. ac-dc diode…
Series DC Voltage Regulator: The output voltage of a d.c. source, whether it is a rectifier or any other machine, changes with the load current as well as with the…
Induction Regulators: An induction regulators is essentially a constant voltage transformer, one winding of which can be moved w.r.t. the other, thereby obtaining a variable secondary voltage. The primary winding is…
Brown Boveri Regulator: In this type of Brown Boveri Regulator, exciter field rheostat is varied continuously or in small steps instead of being first completely cut in and then completely…
Tirril Voltage Regulator: In this type of Tirril Voltage Regulator, a fixed resistance is cut in and cut out of the exciter field circuit of the alternator. This is achieved…
Low Power Factor: The Low Power Factor plays an importance role in ac. circuits since power consumed depends upon this factor. It is clear from above that for fixed power…
Types of Facts Controllers in Power System: The development of FACTS controllers has followed two different approaches. The first approach employs reactive impedances or a tap changing transformer with thyristor…
