Development of a new voltage source inverter (VSI) average model including low frequency harmonics
2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010This paper presents an enhanced average model of a voltage source inverter (VSI) that can accurately predict some of the low frequency phenomena only seen by the switching models. These phenomena include the dead time, voltage drop across switching devices (switch & diode), different modulation and minimum pulse width.

Switches Faults Analysis of Voltage Source Inverter (VSI) using Short Time Fourier Transform (STFT)
International Review on Modelling and Simulations (IREMOS), 2014Three-phase voltage source inverter (VSI) play a very important role in the present industrial life. The knowledge and information about faults characteristic of the VSI is important to prevent failure of equipment, data losses, high maintenance and economic losses.

This paper presents the results and conclusions on loss measurements of a 1 MW dual-stator synchronous motor with redundant voltage source inverter (VSI) drive. Measurements were performed on both 3-phase configuration with paralleled stator systems and 6-phase configuration with 30 degree phase shift between the stator systems (YY30).

This paper presents a modified small-signal model of a voltage source inverter (VSI) that captures model nonlinearities such as dead time 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 model, but none actually derived an ...

Voltage source inverter (VSI) plays an important roles in electrical drive systems. Consistently, expose to hash environmental condition, the lifespan of the electronic component such as insulated-gate bipolar transistor (IGBT) may shorten and many faults related to the inverter especially switches can be occur.
