Exact Modeling of the Voltage Source Converter
IEEE Power Engineering Review, 2001A discrete time, linear time varying model of the three-phase voltage source converter (VSC) is developed. The model is employed to determine the steady state operating characteristics of a VSC taking all ac-dc side harmonic interactions into account. The procedure is based on an exact closed form solution of the system equations and does not rely on ...

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.

Voltage Tolerance Testing of Three-Phase Voltage Source Converters
IEEE Transactions on Power Delivery, 2005This paper proposes a protocol for testing the immunity of three-phase self-commutated converters to voltage dips. An overview of voltage dips due to short circuits and earth faults that may affect a converter is given and their effect on the converter is demonstrated through simulation.

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.

Voltage source converter control under unbalanced grid voltage conditions
2017 XXVI International Conference on Information, Communication and Automation Technologies (ICAT), 2017This 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 ...
