Abstract

An AC-excited rotary electric machine system includes an AC-excited rotary machine having a primary winding connected to an AC power line and a secondary winding connected to a frequency converter. A primary current detector detects a current flowing through a primary winding of an AC-excited rotary machine. In response to a detection value detected by the primary current detector, a secondary current controller changes the range of a command value for the current flowing through the secondary winding of the AC-excited rotary machine to a predetermined range.
