The paper presents a straightforward modelling approach to compute the power loss distribution in GaN HEMT-based three-phase and three-level (3L) active neutral point clamped (ANPC) inverters, for different pulse width modulated techniques. Conduction and switching losses averaged over each PWM switching period are analytically computed by starting from the operating conditions of the AC load and data of GaN power devices. The accuracy of the proposed analytical approach is evaluated through a circuit-based power electronics simulation tool, applied to different carrier-based PWM strategies.

Abstract
The paper presents a straightforward modelling approach to compute the power loss distribution in GaN HEMT-based three-phase and three-level (3L) active neutral point clamped (ANPC) inverters, for different pulse width modulated techniques. Conduction and switching losses averaged over each PWM switching period are analytically computed by starting from the operating conditions of the AC load and data of GaN power devices. The accuracy of the proposed analytical approach is evaluated through a circuit-based power electronics simulation tool, applied to different carrier-based PWM strategies.File in questo prodotto:
