A theoretical and experimental analysis of the steady-state characteristics of a doubly fed synchronous machine (DFSM) is presented. The basic equations and the equivalent circuit that represent the steady state of the DFSM are derived. In the experiments, a three-phase symmetrical wound-rotor terminals were connected to the three-phase bus, and the rotor terminals were connected to the slip-frequency source. A DC generator was directly connected to the DFSM as a load. An AC generator driven directly by a DC motor was used as the slip-frequency source. The theoretical results were confirmed. The rotor iron loss remains an important factor, but its effect is shown to be small when slip is small.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
