Vectorial control of a Voltage Source Converter
2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA), 2010The Voltage Source Converter (VSC) offers the possibility of full four quadrant operation and the total control active and reactive power with the minimal generation of harmonics with the SPWM technique. This paper presents the dq transformation of a VSC and its design of a vectorial control to regulate the DC voltage and reactive power in a rectifier ...

Voltage Dip Mitigation Using Shunt-Connected Voltage Source Converter
IEEE Transactions on Power Electronics, 2006In this paper, a Voltage Source Converter (VSC) connected in shunt with the grid to mitigate voltage dips for sensitive processes is presented. The VSC maintains the magnitude of the grid voltage at the connection point constant by injecting reactive power to compensate for the voltage dip. This is achieved by using a cascade controller, constituted by

Modulation of current-source converters from gating signals for voltage-source converters
2006 37th IEEE Power Electronics Specialists Conference, 2006This paper presents an algorithm to convert the PWM gating signals for a voltage-source converter (VSC) to the signals suitable for gating a current-source converter (CSC). The proposed algorithm requires only the VSC-PWM output signals, therefore, it is easy to be implemented.

Integrated power converter for multiple DC voltage sources
2012 3rd IEEE PES Innovative Smart Grid Technologies Europe (ISGT Europe), 2012The Smarter grid is expected to be supported by various dc power sources such as solar cells or batteries. On the other hand, traditional ac loads like a directly connected induction motors will also be used. In the circumstances, a smart power conversion unit is one of key components, which can integrate these dc or ac apparatus and trade power among ...

FACTS: voltage-sourced converter
2015FACTS (Flexible AC Transmission Systems) was advocated by Dr. Narain G. Hingorani in 1998 [1]. This system is a power electronics device applicable to a power grid. Since FACTS can control power and reactive power positively compared to general transmission devices, it gives flexibility to the power grid in resolving the problems of the power grid.

Experimental validation of an adaptive control for a Voltage Source Converter
2013 American Control Conference, 2013In this work an adaptive controller is designed to provide reactive power compensation and dc voltage tracking of a three phase Voltage Source Converter (VSC). The method relies on a third order model of the VSC which accounts for uncertainty in three system parameters.
