A method of power loss calculation for RB-IGBT matrix converter

The calculation and distribution of power losses for RB-IGBT based matrix converter are discussed in this paper. The on-state performance and switching transients of RB-IGBTs are analyzed in detail. According to this analysis, the calculation models of switching losses and conduction loss are established and a power loss calculation method based on the mathematical fit of experimental test data is proposed. Calculation results are presented to validate the proposed method. In addition, this method can also be used for other power converters using RB-IGBT.
