Improved Dynamic Average Modeling of Synchronous Machine with Diode-Rectified Output

This paper presents an improved dynamic average model for synchronous machine-rectifier system. The dc load current is modeled using its first-order Taylor series expansion throughout the complete averaging period The behavior of the machine-converter in different rectification modes is expressed by mathematical equations makes it suitable for analysis of variable frequency systems. The paper expresses an in-depth description of the modeling approach roach, together with a transient validation of the proposed model, The model is validated through comparison of average model in MATLAB and the experimental results.
