Induction Motor Speed Control Methods: The only way to control the speed of a synchronous motor is to control the input frequency and voltage such as to keep V/f constant.…
Types of Converters in Power Electronics: The different types of converters in power electronics are AC/DC Converters AC/AC Converters The Matrix Converter DC/DC Converters DC/AC Converters Control VSI Current Source…
Motor Control by Static Power Converters: Motor Control by Static Power Converters - Power electronics is a multidisciplinary technology that encompasses power semiconductor devices, converter circuits, electric machines, signal electronics,…
AC Series Motor: A series motor can be run from either dc or ac (single-phase) supply provided that both stator and rotor cores are laminated to limit the iron-loss. Figure…
Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by…
Speed Control of Induction Motor: Stepless control of speed of induction motors cannot be carried out as efficiently and inexpensively as for dc motors. Various methods of Speed Control of…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be…
Synchronous Machine Operation: The Synchronous Machine Operation are examined here under conditions of variable load and variable excitation. One of these quantities will be assumed to be held constant at…
