The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Active-neutral-point-clamped (ANPC) multilevel converter technology (2005, background): “The disadvantage of multiple clamping points is a limitation on the maximum modulation index that is allowed with active power to assure voltage sharing across all the dc link capacitors [7].”
Multilevel Converters: An Enabling Technology for High-Power Applications (2009, background): “addition, sometimes the dc voltage balance in multilevel converters cannot be achieved depending on the modulation index and the power factor of the load [95].”
High-power wind energy conversion systems: State-of-the-art and emerging technologies (2015, background): “As mentioned earlier, the balancing of the dc-link capacitor voltages with the 4L-DCC is very complicated compared to the NPC converter [181], [182].”
Voltage-sharing converter to supply single-phase asymmetrical four-level diode-clamped inverter with high power factor loads (2010, background): “In addition, there is a substantial dependency between modulation index, power factor, and possibility of dc-link capacitor voltage balancing [13], [17], [18].”
