Abstrakt EN: This paper deals with a Sub-Hexagonal Centre PWM (SHCPWM) with variable switching sequence for a topology based on cascaded connection of two converters, so called dual inverter. The SHCPWM is enhanced to consider the last IGBT switching state representing the previous space vector and to balance and reduce power losses among the transistors. The proposed method is compared with the known SHCPWM with the ?xed switching sequence by series of simulations and experimentsonalaboratorydriveaccordingtoevaluationoftotal power losses, maximal IGBT power losses and output voltage total harmonic distortion (THDu).
