Generalized self-driven AC-DC synchronous rectification techniques for single- and multiphase systems [PDF]

open access: yes, 2011
This paper extends the single-phase self-driven synchronous rectification (SDSR) technique to multiphase ac-dc systems. Power MOSFETs with either voltage- or current-sensing self-driven gate drives are used to replace the diodes in the rectifier circuits.

Pwm control of dual diode-clamped converters for PV installation

open access: yes, 2015
Modulation processes have been analyzed in transformer-based photovoltaic system on the basis of cascaded diode-clamped inverters, adjusted by special control scheme with the use of specific voltage vectors. It has been shown, that symbiosis of this control scheme with algorithms of synchronous modulation insures minimization of common-mode voltage and

A new configuration for multilevel converters with diode clamped topology

open access: yes, 2008
Due to the increased use of renewable energy and power elctronic applications, more multilevel converters (MLC) are developed. A Neutral Point Clamped (NPC) inverter is one of the most used multilevel topologies for wind turbine (WT) and photovoltaic (PV) applications. One of the most crucial points in this type of converter is dc-voltage control.
