Aldabergenov, M.; Familiant, Y. L.; Ruderman, A.
(Nazarbayev University, 2014)
The authors address the problem of optimal current quality for a single-phase
multilevel inverter with a staircase modulation (Fig.1). The current quality is characterized by current
ripple Normalized Mean Square (NMSc). ...

The multilevel inverter optimal voltage quality problem is formulated in time domain in
order to account for all switching harmonics.
The numerical solutions establish theoretical
voltage quality lower bounds for a ...

Stack Multicell Converters (SMC) is a class of converters derived from a classic Flying
Capacitor Converter (FCC). The paper presents simple closed-form analysis of average capacitor natural
voltage balancing dynamics ...

While most of the past research addressed the analysis of natural voltage balancing
in Flying Capacitor Converters (FCC) (Fig.1, 2) using frequency domain Fourier based methods, the
authors attack the problem in time ...
