Modeling of a Three-Phase Diode Bridge Rectifier Connected to a Three-Phase AC Source via an Inductive Filter

This study introduces an intuitive method for modeling a three-phase diode bridge rectifier connected to a three-phase AC source via an inductive filter. The developed model is derived from the model of a three-phase PWM rectifier, and the impact of diode parasitic capacitance and resistance is represented by the inclusion of three first-order filters. The simulation results closely match the experimental data, validating the effectiveness of the developed model.
