Abstract	The output voltage of synchronous generator regulated constantly by field current control in excitation system. High frequency PWM converter (current control mode buck converter) type excitation system for synchronous generator is able to control exciter current when the load change happened. This paper deals with the design and evaluation of the excitation system for a synchronous generator to improve the steady state and transient stability. The simulation and experimental results show that the proposed excitation system is able to improve the response time by the DVR(digital voltage regulator) of 50[㎾] synchronous generator.
