New standards for power losses measurements 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 or Silicon/Silicon Carbide (SiC) as well as full SiC systems in Two-Level topology are shown to increase the inverter efficiency.
