This paper shows a very simple method of determining the range of field voltages to be applied to an isolated synchronous generator from no-load to full load while maintaining the rated terminal voltage on the stator terminals. The d-q rotor reference frame equations were used for the calculations and it is shown that values of the field voltages determined follow a simple quadratic relationship that offer a very simple control scheme, dependent on only the stator current.
