Research And Design Of Rotating Converter Based On Synchronous Generator Brushless Excitation System

This paper introduces a new design of rotating converter which gets an application in the brushless excitation of synchronous generator. And this research will break through the traditional concept of static converter. Compared to the traditional converter, the new one can transform electric power from a static part to a rotary part without an electrocircuit connection, which makes the contactless power transform come true. One application of this converter is to supply a steady and regulable excitation circuit for synchronous generator by integrated its second winding with the motor while its primary winding is static.The thesis gives two methods of the rotating converter design paticullarly: flyback and fullbridge, and explains how the circuits are designed. It also gives the results of simulation and experiment. The comparision of the two transformers shows that the flyback rotating converter can just transform signal or low power while the fullbridge one conducts the larger. In condusion, the research of rotating converter will promote the progress of the synchronous generator brushless excitation system and illuminate a new direction of the power electric converter.This paper design and analysis of rotating-transformer, prove this transformer is not as good as traditional transformer. So using a new plane winding.For realizing the function of rotating converter, this paper make a experimental table.
