Voltage source converter control under unbalanced grid voltage conditions

2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017
This paper proposes a novel control method for voltage source converter (VSC) connected to grid under unbalanced voltage conditions. The method is based on utilizing the full control capabilities of the switching converter. The proposed method makes the voltage source inverter (VSI) supply the voltages according to the requirements of the load and/or ...

Modulation of current-source converters from gating signals for voltage-source converters

2006 37th IEEE Power Electronics Specialists Conference, 2006
This 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), 2012
The 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

2015
FACTS (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.
