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.

与三电平H桥逆变器相比，五电平有源中性点钳位（5L-ANPC）H桥逆变器具有较高的输出电压电平，较高的输出功率和较低的电流谐波含量。因此，它有潜力应用于船舶集成动力系统。本文提出了一种用于5L-ANPC H桥逆变器的空间矢量脉冲宽度调制（SVPWM）方法。首先，基于对开关约束，开关时间和共模电压的分析来选择可用的开关矢量。然后，根据逆变器的中性点电位和浮动电容器电压的控制要求，计算出每个开关矢量的动作时间。基于减少切换时间的原理来确定不同间隔中的切换向量的顺序。最后，建立了硬件在环实时仿真实验平台，以验证该方法的有效性。
