the efficiency and power factor are high as the operation is restricted b/w syn. Speed and max. Torque point at all frequencies.
4. Drop in speed from no lad to full load is small.
Fig. Shows the torque-developing characteristic of every motor: the Volts per Hertz ratio (V/F). We change this ratio to change motor torque. An induction motor connected to a 460V, 60 Hz source has a ratio of 7.67. As long as this ratio stays in proportion, the motor will develop rated torque. A drive provides many different frequency outputs. At any given frequency output of the drive, you get a new torque cur..................[:=> Show Contents <=:]

describe these advanced integration techniques we can use a typical power electronics system. A Distributed Power Supply (DPS) system can be used for this purpose
DPS SYSTEM
The complete circuit diagram of DPS system is shown in figure 1. In this DC-DC converter, the primary dc supply is split in with the help of capacitors and then inverted to high frequency ac by MOSFET by half bridge inverter. The resonant capacitor voltage is transformer coupled, diode rectified and then filtered to get the output dc voltage .

The active part of the DPS system contains a po..................[:=> Show Contents <=:]
