Abstract
The paper develops a diode-bridge rectifier model based on dynamic phasors (DP) concept. The model is targeted at the functional modeling level according to the multi-layer modeling definition. The performance and efficiency of the developed model have been revealed by comparison against abc three-phase model and dq0 functional model under balanced and unbalanced conditions. The comparison shows the DP model is more accurate than dq0 model in the discontinuous dc-link current case and is the fastest model under unbalanced conditions. The interface between DP models and normal time-domain three-phase systems is also introduced, which allows combination of the DP model with other standard three-phase models and make the application of the DP model more convenient.
