Advancement in Electric Machines using Power Electronic Converters

Abstract
This paper represents automatic synchronization of alternators. This unit is developed for the parallel connection of alternators. This unit is developed to overcome on the disadvantages of conventional methods of synchronization. In this unit the voltage, frequency of the incoming alternator is compared with the reference alternator with the help of Peripheral Interface Controller (PIC). So now a days the demand of electricity is increasing, we can meet such a huge load demand by using this unit. The chopper is used to vary the field excitation of the alternator. The microcontroller will produce PWM [Pulse Width Modulation] signal, which acts as gate drive circuit to power electronic converter [chopper].
