Small-Signal Model of Voltage Source Inverter (VSI) and Voltage Source Converter (VSC) Considering the DeadTime Effect and Space Vector Modulation Types

IEEE Transactions on Power Electronics, 2017
This paper presents a modified small-signal model of a voltage source inverter (VSI) and a voltage source converter (VSC) that captures model nonlinearities such as deadtime and modulation effects that were not presented in the literature. Previous research has concentrated on developing compensation methods for these types of phenomena in a switching ...

Research on the Voltage Source Converter in VSC-HVDC

2010 International Conference on Power System Technology, 2010
Voltage Source Converter (VSC) based High Voltage Direct Current (VSC-HVDC) transmission technology is a novel transmission technology on the basis of pulse width modulation (PWM) technology and fully-controlled power electronics devices. The output performance of VSC mainly depends on its modulation algorithm. A new kind of SVPWM algorithm based on 60°

Parabolic PWM for Current Control of Voltage-Source Converters (VSCs)

IEEE Transactions on Industrial Electronics, 2010
A novel parabolic carrier pulsewidth modulation (PWM) method is proposed in this paper for direct current control in a voltage-source converter (VSC). This method employs a pair of parabolic PWM carriers (a positive one and a negative one) to determine the switching states of the two switches in a converter phase leg while limiting the current tracking

Reachability analysis for a grid-connected voltage-sourced converter (VSC)

2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018
To analyze a system accurately, all of its parameters, initial conditions, and inputs are needed; however, finding their precise value is not possible in practice. In addition, uncertainty of a system cannot be considered in conventional methods for system analysis.
