“…The variations of v err4 an with respect to the values taken by the phase current i a are then represented in green in Figure 5 (curve in 1 |i a | for |i a | ≥ I th ). The voltage drop caused by other imperfections, V err1,2,3 an (dead times, switching times, and voltage drop in components), is also depicted in red on this figure, along with the resulting voltage drop shown in blue.…”

“…In pursuit of reducing reliance on fossil fuels and transitioning to renewable energy sources, the electrification of numerous industrial systems stands as a primary objective for many countries. Moreover, in efforts to mitigate greenhouse gas emissions and air pollution, electrifying transportation systems can play a crucial role [1]. Consequently, the utilization of various types of electrical machines, such as synchronous machines, has witnessed significant growth in recent years [2,3].…”

This study investigates the nonlinearities in three-phase inverters for SiC-based systems and compares their performance to IGBT-based systems. An analytical model of inverter voltage distortion is developed, which accounts not only for dead time (td), switching delay time, switching frequency (fs), and voltage drops of power devices, but also for output parasitic capacitance (Cout). Experimental tests validate the model, which provides a more accurate estimate of the inverter’s output phase voltage distortion. The power device characteristics are obtained from datasheets, while Cout is determined through experimentation. Three-phase inverters with varying switching frequencies, fundamental frequencies, and dead-time values are used in simulations and experiments to determine the influence of nonlinearity on phase voltage deviation and current distortion. The results show that, due to SiC devices’ faster switching time, the phase voltage deviation and phase current distortion are lower in SiC-based inverters than in IGBT-based ones for high-frequency applications, as the dead time can be reduced.
