Comparative Study of Average Model of Diode Rectifier with the Model Developed by Modified Nodal Analysis Method

Abstract

This paper presents two methods for modeling three phase diode rectifier. The average model of the three phase diode rectifier is compared with the rectifier model developed by Modified Nodal Analysis method. The simulation is done in C environment and the waveforms of output voltage for both the methods are obtained. The average model gives appreciable results with simple equations, but model ling the rectifier using modified nodal analysis method is quite time consuming and a tedious task. The paper discusses the advantages of using average model over the other model.
