Abstract: This paper investigates the fault-tolerance control of a multilevel cascaded NPC/H-bridge (CNHB) inverter. The fault-tolerance control method has been widely used for multilevel inverters, such as the neutral-point voltage-shifting control, which can operate for a certain period of time by compensating for the phase voltage of a faulty stack even if one stack is broken. Even though the three-phase equilibrium is maintained in the case of failure by using the conventional neutral-point voltage-shifting control,… Show more

“…A total of 12 Si-IGBT and 6 SiC-MOSFET switches. It is worth mentioning that the total number of the switches in HANPC is the same when compared to the conventional ANPC but the HANPC is considered as a new topology that can reduce the switching losses and enhancing the system performance by reducing the total harmonic distortion (THD) and work on higher switching frequencies with its unique switching sequences [30]. It also replaces the inner two IGBTs (S a1 /D a1 -S a4 /D a4 ) with two MOSFETs (Q a1 /D Qa1 and Q a2 /D Qa2 ) switches.…”

“…Similarly, in [29] and [30], the fault-tolerant capability for different topologies converters was investigated; where the proposed fault-tolerant method in [29] focused on the equivalent substitution of voltage space vector for cascaded H-bridge multilevel inverter. While, in [30], the proposed method applied for NPC/H-bridge (CNHB) inverters. It mainly works on maintaining the three-phase equilibrium and minimizing the imbalance between the stacks.…”

“…The benefits of the multilevel power inverter topologies are as follows: improved output waveforms, low electromagnetic interference (EMI), and small filter size [1][2][3]. Neutral point clamped (NPC), flying capacitors, and cascaded H-bridge (CHB) inverters [4][5][6][7][8][9][10][11][12][13][14] are three basic multilevel inverter structures. Among these structures, the CHB structures [9][10][11][12][13][14] have unique merits: higher output voltage, flexibility, and power levels.…”
