| Abstract |
This paper presents a modulation technique, which combines the known space-vector-pulse-widthmodulation (SVPWM) and the discontinuous-pulse-width-modulation (DPWM). This enables thepossibility to set the switching losses freely within a certain border band. A possible area ofapplication is the reliability of IGBT-inverters modules, where junction temperature swings can bereduced by influencing the power losses. The functionality is underlined by the analytical derivation ofthe switching and conduction mean power loss equations which are verified by measurements incertain operation points. |
