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…
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…
Cycloconverter Feeding Three Phase Induction Motor Drive: Variable frequency supply to an induction motor may be obtained by using a cycloconverter. As has already been discussed, a cycloconverter is a…
Static Scherbius Drive: The main limitation of the Kraemer drive discussed is the operation at sub-synchronous range due to diode rectifier. Super synchronous speeds can be achieved if the power…
Speed Control Using Slip Energy Recovery Schemes: The foregoing discussion makes it very clear that the methods of voltage control and rotor resistance control have poor efficiency, particularly at low…
