Three-phase voltage-source convertor with controlled DC current for the minimisation of filter capacitance

IEE Proceedings B Electric Power Applications, 1990
The paper presents a novel control strategy for the output DC current in a three-phase AC/DC convertor using diodes, combined with a boost-type DC chopper. This contributes to the suppression of the output voltage ripples so that the size of the filter capacitor can be minimised.

Steady-state and transient characteristics of a single-way step-down PWM GTO voltage-source convertor with sinusoidal supply currents

IEE Proceedings B Electric Power Applications, 1989
The paper investigates the steady-state and transient characteristics of a single-way step-down voltage-source convertor, in which the introduction of pulsewidth modulation makes it possible to obtain the sinusoidal supply currents and the regulated output voltage.

Managing microgrid power generation by using back to back voltage source convertor

IEEE PES Innovative Smart Grid Technologies, Europe, 2014
The paper presents an algorithm for managing a microgrid which connected to the main grid via Back To Back Voltage Source Converter (BTB VSC) which can exchange power with adjacent grid. The proposed microgrid consists of a wind turbine generation unit, two photovoltaics generation units, a storage system, a fuel cell generation unit, a micro turbine ...

For prototype super-conducting magnetic energy storage (SMES) [voltage source convertor control scheme]

Proceedings IPEMC 2000. Third International Power Electronics and Motion Control Conference (IEEE Cat. No.00EX435), 2002
In this paper, a synchronous frame based control method of voltage source converter (VSC) for superconducting magnetic energy storage (SMES) is presented. The model and the feedforward decoupling method are described. The design of the regulators is depicted in detail. Simulations and experiments are both demonstrate the studies.

A novel method for estimation of IGBT switching losses in voltage source convertors through EMT simulations

2016 IEEE 2nd Annual Southern Power Electronics Conference (SPEC), 2016
This paper introduces a simplified method for estimating switching energy losses in an IGBT device of a Voltage Source Converter (VSC) using Electro-Magnetic Transient (EMT) simulations. By considering the switching process as characterized by an equivalent circuit model of a unit cell that represents one leg of a VSC, equations are derived to evaluate
