“…Since the averaged circuit still fulfils the Kirchhoff's Laws, once the switches have been replaced by the corresponding sources, the model of the converter can be developed directly by circuit analysis techniques. In [121] this averaging method is applied to a fivelevel CHB. Modeling methods have also been developed for the α-β-γ plane [119], [122] .…”

Multilevel converters are considered today as the state of the art power conversion systems for high power and power quality demanding applications. This paper presents a tutorial on this technology, covering the operating principles, the different power circuit topologies, modulation methods, technical issues and industry applications. Special attention is given to established technology already found in industry with more in depth and self-contained information, while recent advances and state of the art contributions are addressed with useful references. This paper serves as an introduction to the subject for the not familiarized reader, as well as an update or reference for academics and practicing engineers working in the field of industrial and power electronics.

“…Once the multilevel inverter transfer function in s ‐domain is given by (12), neglecting the resistance losses and considering the PCC voltage as a disturbance

I_{comp} false(s false) = \frac{V_{H} + V_{M} + V_{L}}{s L} s_{stc} (s)

The functions s stc ( t ) may be assumed as unit [36, 37]. Therefore the closed‐loop transfer function considering the PI controller is given by the following equation

\begin{matrix} right leftthickmathspace.5em \\ \frac{I_{comp} (s)}{I_{comp}^{*} (s)} \\ = \frac{(V_{normalH} + V_{normalM} + V_{normalL}) k_{normalp} (s T + 1)}{s^{2} L T + s k_{normalp} (V_{normalH} + V_{normalM} + V_{normalL}) T + k_{normalp} (V_{normalH} + V_{normalM} + V_{normalL})} \end{matrix}

where k p and T are the proportional gain and time constant, respectively.…”

“…Different applications have been developed using the multilevel cascade converter: Synchronous rectifiers [5], renewable energy integration systems [6], inverters [7], Statcoms [8] and active filters [9]. For each application, specific control strategies have been designed, being the DCLink voltages control the most important challenge in this power converter topology.…”
