s similar to that of the personal computer. More features, better performance, and lower cost with successive generations. Unlike computers, however, drives have dramatically improved in their reliability and ease of use. And also unlike computers, the typical drive of today doesn't spew gratuitous harmonics into your distribution system-nor does it affect your power factor. Drives are increasingly becoming plug and play. As electronic power components improve in reliability and decrease in size, the cost and size of VVVFDs will continue to decrease. While all that is going on, their perform..................[:=> Show Contents <=:]

m. 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 .

Fig 1: DPS System

The active part of the DPS system contains a power switching stage with two MOSFETs and their drive circuit. The drive circuit contains hig..................[:=> Show Contents <=:]
