Mitigation Methods of Voltage Disturbances and Harmonic Currents of PWM Two-Level Inverter Supplying The 6-Pulse Diode Rectifier

by Jerzy Ryszard Szymanski and Marta Zurek-Mortka

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 1, Page # 294–301, 2020; DOI: 10.25046/aj050137

Abstract:

In fast charging station for Battery Electric Vehicles (BEVs) the three-phase PWM (Pulse Width Modulation) inverters generate parasitic Differential-Mode Voltages (DMV) and Common-Mode Voltages (CMV). Parasitic voltages are a side effect of using the width modulation to shape the phase-to-phase inverter’s voltage. In this article the authors present a mathematical description of the differential-mode (DM)…

Dc-link voltage drift compensation in a four level Double- Star Converter using redundant states via phase-shifted PWM strategy

by Carlos A. Reusser

Advances in Science, Technology and Engineering Systems Journal, Volume 3, Issue 4, Page # 53–58, 2018; DOI: 10.25046/aj030407

Abstract:

The following work introduces the use of the available Redundant switching states introduced by the double star four level converter topology, for its application in a medium voltage variable speed drive under a wide range of operation loads. Redundant switching states are obtained using multi-carrier phase-shifted pulse width modulation (PWM) strategy. The converter performance is…
