Abstract :
New standards for power losses measurement for variable speed drives are presented. The power losses of typical variable speed drives are analyzed and future alternatives to increase their efficiency investigated. Solutions with Silicon (Si) technology in Three-Level topology or Silicon Carbide (SiC) switches in Two-Level circuit are possibilities to increase the inverter efficiency.
