A brushless exciter model incorporating multiple rectifier modes and Preisach´s hysteresis theory

A brushless excitation system model is set forth that includes an average-value rectifier representation that is valid for all three rectification modes. Furthermore, magnetic hysteresis is incorporated into the d-axis of the excitation using Preisach´s theory. The resulting model is very accurate and is ideal for situations where the exciter´s response is of particular interest. The model´s predictions are compared to experimental results.
