Methods to Leading Power Factor: We have seen that a phase controlled converter requires reactive power for control and commutation. The harmonics do not contribute to the active power loading…
Three Phase Drives: Single phase drives discussed in the previous section are employed for low and medium powers. When the power of the drive is very large the three-phase converter…
Starting Methods of Synchronous Motor for LCI: It has been pointed out that a Starting Methods of Synchronous Motor for LCI, even though complicated in its construction, has an advantage…
Current Source Inverter Fed Synchronous Motor Drive: A synchronous motor draws a stator current which is independent of stator frequency when V/f and E/f are maintained constant and armature resistance…
Voltage Source Inverter Fed Synchronous Motor Drive: An inverter fed synchronous motor has been very popular as a converter motor in which the synchronous motor is fed from a CSI…
Synchronous Speed on Variable Frequency Supply: As has already been discussed, the speed of a synchronous motor can be varied by supply frequency variation similar to an induction motor. The…
Synchronous Motor Drives: Variable frequency drives employing synchronous motor are receiving considÂerable interest, and are even becoming competitors to both induction motors and dc motors. These are popular as drives…
Current Source Inverter Fed Induction Motor Drive: Current Source Inverter Fed Induction Motor Drive - In a voltage source inverter fed induction motor the applied voltage to the stator is…
