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 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…
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.…
3 Phase Induction Motor Construction: A converter fed 3 Phase Induction Motor Construction has the following advantages over a line fed motor: 1.Smooth start up is guaranteed by variable frequency…
Cycloconverter: A variable frequency supply for feeding a three phase motor can be obtained from a cycloconverter which operates on a 50 Hz supply and provides a variable frequency supply…
Features of Variable Voltage Inverters: The inverter has an impressed dc voltage. The output voltage of the inverter is decided by the firing and duration of the thyristors. The conduction…
Two Quadrant Chopper: Sometimes a chopper may be required to provide a two quadrant operation by retaining the current direction in both motoring and braking modes. Such a Two Quadrant…
Three pulse converter with freewheeling diode: A Three pulse converter with freewheeling diode across the load terminals is depicted in Fig. 3.56. The diode is meant to provide an alternative…
