“…The only difference is the usage of retention capacitors instead of retention diodes. The final topology, a cascade full bridge inverter connected in series, was suggested by Marchesoni et al To obtain the desired voltage on the inverter output, independent multiple full phase bridge inverters are required [26]. The advantage of multi-level inverters [27]- [29] is that they can be used in applications requiring high power and high voltage.…”

“…Among numerous multilevel converter topologies that have been proposed over the past decades, three classic or traditional topologies exist. These topologies are the neutral point clamped (NPC) [10], [11], the flying capacitors (FCs) [12], and the cascade H-bridge (CHB) [13]. In CHB converters, several isolated DC sources are necessary to produce active power.…”

This study proposes a novel five-level three-phase hybrid-clamped converter composed of only six switches and one flying capacitor (FC) per phase. The capacitor-voltage-drift phenomenon of the converter under the classical sinusoidal pulse width modulation (SPWM) strategy is comprehensively analyzed. The average current, which flows into the FC, is a function of power factor and modulation index and does not remain at zero. Thus, a specific modulation strategy based on space vector modulation (SVM) is developed to balance the voltage of DC-link and FCs by injecting a common-mode voltage. This strategy applies the five-segment method to synthesize the voltage vector, such that switching losses are reduced while optional vector sequences are increased. The best vector sequence is then selected on the basis of the minimized cost function to suppress the divergence of the capacitor voltage. This study further proposes a startup method that charges the DC-link and FCs without any additional circuits. Simulation and experimental results verify the validity of the proposed converter, modulation strategy, and precharge method.

“…Multilevel cascade converters, also named cascaded Hbridge converters, were first presented in 1988 [1]. Since then they have been a focus of researchers because they present several advantages compared with other multilevel converter topologies in terms of modularity, simplicity and number of levels with minimum number of power semiconductors [2]- [4].…”
