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…
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…
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…
Field Oriented Control of Induction Motor: In the slip controlled drives using VSI or CSI discussed in the foregoing secÂtions, the stator voltage or stator current is controlled using slip…
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…
PWM Inverter Fed Induction Motor Drive: Voltage control in the square wave inverter has been external to the inverter, by means of a phase controlled rectifier on the line side.…
Square Wave Voltage Source Inverter Fed Induction Motor Drive: Square Wave Voltage Source Inverter Fed Induction Motor Drive is a kind of dc link converter, which is a two stage…
Speed Control of Variable Frequency Induction Motor: Speed Control of Variable Frequency Induction Motor of a squirrel cage induction motor can be controlled very effectively by varying the stator frequency.…
