Abstract

In this paper, a study of resonant snubbers with auxiliary switches is presented as applied to three-phase current stiff power converter (CSC) topologies targeted for electric drives applications. Several realizations of CSCs with resonant snubbers are identified and characterized from a generalized three-phase commutation cell. The modulation characteristics associated with the operation of the CSCs with resonant snubbers are analyzed using the space vector approach. Simulation results are presented to illustrate the key aspects in this discussion. Experimental results are included for selected cases
