Power Routing for Cascaded H-Bridge Converters [PDF]

open access: yesIEEE Transactions on Power Electronics, 2017
Modular power converters are expected to play a major role in medium- and high-voltage/power applications. Normally, each module processes the same amount of power; however, this does not take into consideration that different modules can have a different remaining useful lifetime. This paper proposes the concept of power routing for cascaded H-bridge (

Research on Cascaded H-bridge SVG

open access: yesJournal of Networks, 2014
Due to the sharp increase of the non-linear loads, the power quality lagged behind the need for an adequate power system. With a fast response, low loss, low output harmonic current, SVG has become the mainstream of dynamic reactive power compensation devices.
