Circulating current control for modular multilevel converters with (n+ 1) selective harmonic elimination—PWM

A Perez-Basante, S Ceballos… - … on Power Electronics, 2020 - ieeexplore.ieee.org
Modular multilevel converters (MMCs) require control of the circulating current, i circ, to
improve their operation and efficiency. This is particularly important when low switching …

Influence of the zero sequence voltage on the design of a series active filter

A Reinhold, U Raedel, R Grohmann… - PCIM Europe 2016; …, 2016 - ieeexplore.ieee.org
This paper discusses a series active power filter (APF) for a three-phase diode rectifier. The
series APF reduces the AC side harmonic current which is drawn by the rectifier and …
