Feasible Operating Boundary Extraction for MW‐Class SiC Inverters in High‐Speed Drives

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper develops a unified electrothermal framework to extract feasible operating boundaries for megawatt‐class silicon carbide inverters used in high‐speed drives. Two‐level, T‐type neutral‐point‐clamped, and active neutral‐point‐clamped topologies are compared at 800 and 1500 volts under simultaneous efficiency, junction‐temperature, and current ...

Three-Phase inverter Controlled by ISCPWM and DPWM-S1

Elektronika ir Elektrotechnika, 2012
This paper presents the implementation of the ISCPWM-DPWM-S1 control technique on a microcontroller. This technique was developed due to the modulation of a discontinuous signal DPWM-S1 with an inverted sinusoidal signal ISCPWM. Good results were obtained for the switching losses on the power transistors, which are lower, and for the amplitudes of the ...
