Single-phase H-bridge cascaded neutral point clamped (CHB-NPC) inverter is a popular choice for photovoltaic power generation, high power motor drive, and static reactive power compensators due to its high voltage withstand capability, low cascaded unit DC power requirement, and high efficiency and reliability [4, 5, 6].
An experimental platform is established to verify the correctness and superiority of the method. With the continuous progress of power electronics technology, single-phase multilevel inverters have been widely used in a variety of applications, and have significant advantages over two-level inverters .
Firstly, the topology of single-phase CHB-NPC inverter is analyzed, and the subset of effective voltage vectors is simplified and the redundant states of the switches are optimized for the problem of more switching vectors in the traditional FCS-MPC, which reduces the amount of computation and improves the computational efficiency.
Based on the prediction models for the DC-side capacitor voltage and current tracking of the single-phase CHB-NPC inverter, derived in the previous section, it can be assumed that the inverter output current will track the given reference current at moment k + 1. Therefore, we can conclude that
More appropriate solution is clamping the CM voltage to half of the dc-link voltage during zero voltage level production. To do so, bus capacitors can be categorized into two similar series capacitors and a clamping cell ought to be located between the midpoint of the series bus capacitors as well as full-bridge module.
