Neutral point clamped (NPC) topology is a common three-level topology, and it is widely used in medium and high-power photovoltaic inverters. In this three-level NPC inverter, the voltage stress on each power device is only half of the bus voltage. Its output voltage harmonic content is lower compared with the two-level inverters. However, the NPC inverter has the problem of uneven power loss distribution over the power devices [1]. Uneven loss distribution will increase the design requirements for the heat sink, resulting in larger volume of the heat sink, which is not conducive to improving the power density of the inverter. To solve this problem, T. Bruckner from the Dresden University of Technology and S. Bemet from the ABB Corporate Research first proposed the active neutral point clamped (ANPC) three-level topology at the IEEE-PESC conference in 2001 [2]. The ANPC topology replaces the clamp diodes in the NPC topology with active switches. Thus, the PWM (pulse width modulation) control of the ANPC topology is more flexible. When the ANPC inverter outputs zero state, there are multiple redundant loops to choose from. By rationally selecting the zero-state loop, the loss balance of each devices can be achieved. In addition, the flexible commutation mode of the ANPC topology also provides the possibility for hybrid configuration of power devices. According to the different switching and on-state characteristics of power devices, they are assigned to different positions in the ANPC topology. When combined with specific commutation modes, it is possible for the inverters to achieve higher efficiency and power density
