The detailed switch-level models of front-end diode recti fi er loads can be readily implemented using a number of transient simulation programs, such as PSCAD/EMTDC, and the toolboxes in Matlab/Simulink. To improve the simulation ef fi ciency for the system-level studies, the so-called dynamic ave rage models have been widely used by researchers and en- gineers. Recently, several aver age-value modeling methodologies for the conventional three-phase (six-pulse) front-end recti fi er loads have been discussed, and the dynamic performance of sev- eral developed models has been demonstrated in discontinuous and continuous modes. In this paper, the effects of topological variations of the ac-side fi lters on the system performance are investigated. Also, the steady-st ate and dynamic impedances pre- dicted by the average models under balanced and unbalanced operation are compared. The studies and analyses presented here extend and complement those set forth in the preceding companion publication.
