Operation, Control, and Applications of the Modular Multilevel Converter: A Review
TL;DR: A general overview of the basics of operation of the MMC along with its control challenges are discussed, and a review of state-of-the-art control strategies and trends is presented as mentioned in this paper.
Proceedings ArticleDOI
Active-neutral-point-clamped (ANPC) multilevel converter technology
TL;DR: In this paper, a multilevel power conversion concept based on the combination of neutralpoint-clamped (NPC) and floating capacitor converters is proposed, where the voltage balancing across the floating capacitors is achieved by using a proper selection of redundant switching states, and the neutral-point voltage is controlled by the classical dc offset injection.

A zero-voltage and zero-current switching three-level DC/DC converter
TL;DR: In this article, a zero-voltage and zero-current switching (ZVZCS) three-level DC/DC converter is presented, which uses a phase shift control with a flying capacitor in the primary side to achieve ZVS for the outer switches.
Journal ArticleDOI
A Modified Direct Power Control Strategy Allowing the Connection of Three-Phase Inverters to the Grid Through $LCL$ Filters
TL;DR: In this paper, the authors proposed a novel approach to adapt a conventional direct power control (DPC) for high-power applications, where a third-order LCL filter is frequently required.
