Excellent performance of the BaSIC topology has been demonstrated in previous chapters by employing silicon depletion mode MOSFETs (DMMs) and silicon enhancement mode MOSFETs (EMMs) as the non-linear resistances placed in series with the SiC power MOSFET. These two approaches are contrasted in this chapter. Trade-off curves between the improvement in short-circuit time and the increase in the on-resistance or the switching losses are developed for the same SiC power MOSFET with the two approaches.

摘要

Excellent performance of the BaSIC topology has been demonstrated in previous chapters by employing silicon depletion mode MOSFETs (DMMs) and silicon enhancement mode MOSFETs (EMMs) as the non-linear resistances placed in series with the SiC power MOSFET. These two approaches are contrasted in this chapter. Trade-off curves between the improvement in short-circuit time and the increase in the on-resistance or the switching losses are developed for the same SiC power MOSFET with the two approaches.
