Critical Parameter Identification in Power Electronic Inverters Using Optimized Monte Carlo Analysis Under Parameter Uncertainties

There is a significant effort in understanding the cumulative impact of tolerance chains on the behavior of a power-electronic device. This step is particularly important to optimize design margins and ensure homologation of a serieslevel development. Nevertheless, the computational cost of a brute-force analysis can b...

An Experimental Assessment of Multi-Objective Pulse Pattern Optimization for Synchronous Machine Drives

This paper investigates the impact of optimized pulse patterns (OPPs) on the efficiency of two-level voltage-source inverters (VSIs) and permanent magnet synchronous machines (PMSMs) using a machine test bench. Due to the complex behavior of iron losses in electrical machines, proxy metrics such as current total harmon...
