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.
