TL;DR: This paper covers the high-power voltage-source inverter and the most used multilevel-inverter topologies, including the neutral-point-clamped, cascaded H-bridge, and flying-capacitor converters.

TL;DR: The basic operation and the most used modulation and control techniques developed to date of neutral-point-clamped inverters are presented and some technological problems such as capacitor balance and losses are presented.

TL;DR: A review of the latest achievements of modular multilevel converters regarding the mentioned research topics, new applications, and future trends is presented in this article, where the authors present several attractive features such as a modular structure, the capability of transformer-less operation, easy scalability in terms of voltage and current, low expense for redundancy and fault tolerant operation, high availability, utilization of standard components, and excellent quality of the output waveforms.

TL;DR: The operation of modular multilevel converter is described, an emerging and highly attractive topology for medium- and high-voltage applications and a new pulsewidth-modulation scheme for an arbitrary number of voltage levels is introduced and evaluated.

TL;DR: This paper introduces a new iterative design procedure of L and LCL filters for low-voltage active-front-end PWM two-level voltage source converters using the analytical expression of the converter harmonic voltages by Bessel functions.
