Optimized pulse patterns (a unique 'frequency-less' modulation scheme) combined with dead time compensation significantly reduce distortion and harmonics in the electromotor, bringing critical benefits in size, weight, cooling needs and NVH to the drivetrain. Implemented on a flexible and fully customizable silicon-carbide-based inverter platform, case studies are discussed to compare simulations with real-world results. Inverter solutions from the power electronics, over fully functional reference designs to control software, are presented.
