Research on AC Voltage Regulating System of Doubly Salient Electro-Magnetic Generator

An ac voltage regulating system of doubly Salient Electro-magnetic Generator has been performed in this paper. In order to maintain the high voltage 360VDC stable, the dual boost converter with fixed frequency PWM controlled is adopted. Three-phase dual buck inverter was adopted to output 115VAC/400Hz. the generating system configuration, control strategy of dual boost converter and three-phase dual buck inverter voltage regulating technology and work principle of the dual boost converter, Current commutation, load, and generator speed influence on the high voltage regulator has been analyzed. In the end, the prototype is implemented and the results of the experiment verified the theory analysis. The experimental results shows that the system efficiency is high than 91% at different condition.
