Performance characteristics and average-value modeling of auxiliary resonant commutated pole converter based induction motor drives

The auxiliary resonant commutated pole (ARCP) converter is currently of int ense interest for use in a variety of power electronic converters, land is one of the cornerstones of the Navy's Power Electronic Building Block (PEBB ) effort. In this paper a detailed discussion of the required switching tim es needed to achieve completely soft switching operation with only one curr ent sensor per phase is set forth. Based on this analysis, an average-value model of the ARCP converter is derived and used to explore the output char acteristics of the ARCP converter. It is shown that large loads at high pow er factors can cause the ARCP output voltage to drop substantially, Compute r simulations and laboratory data are used to validate this analysis.
