Space vector modulation and carrier-based pulse width modulation strategies are widely employed in voltage source inverters used in electric vehicles. However, high-power and high-speed applications such as electrified aircraft and locomotives demand higher efficiency, leading to innovative modulation methods that can reduce the switching losses. In this paper, the applicability and advantages of the optimized pulse pattern (OPP) modulation strategy for three-level active neutral point clamped inverter (3L-ANPC) for electrified aircraft propulsion has been investigated through Simulink/PLECS simulations. The preliminary results suggest that the OPP can reduce the switching losses while offering low current THD.

Abstract
Space vector modulation and carrier-based pulse width modulation strategies are widely employed in voltage source inverters used in electric vehicles. However, high-power and high-speed applications such as electrified aircraft and locomotives demand higher efficiency, leading to innovative modulation methods that can reduce the switching losses. In this paper, the applicability and advantages of the optimized pulse pattern (OPP) modulation strategy for three-level active neutral point clamped inverter (3L-ANPC) for electrified aircraft propulsion has been investigated through Simulink/PLECS simulations. The preliminary results suggest that the OPP can reduce the switching losses while offering low current THD.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
