Abstract

When compared with the three-level H-bridge inverter, the five-level active-neutral-point-clamped (5L-ANPC) H-bridge inverter has high output voltage level, high output power, and lower current harmonic content. Thus, it has the potential to be applied to the vessel integrated power systems. This paper proposes a method of space vector pulse width modulation (SVPWM) for the 5L-ANPC H-bridge inverter. First, the selection of the available switching vectors is based on an analysis of the switching constraints, switching times, and common-mode voltage. Then, according to the control requirements of the neutral-point potential and the floating capacitor voltage of the inverter, the action time of each switching vector is calculated. The sequence of the switching vectors in different intervals is determined based on the principle of reducing the switching times. Finally, a hardware-in-loop (HIL) real-time simulation experimental platform is established to verify the proposed method.
