In this paper, the authors examined the existing medium voltage drive formats, their advantages and disadvantages, and proposed new standards implemented overseas to limit the effect of harmonics on the electricity supply system, and how these limits impacted on the design of new generation VSDs.Abstract:
This paper outlines the approach taken in the development of a new medium voltage variable frequency drive. It examines the existing medium voltage drive formats, their advantages and disadvantages. It also outlines new standards implemented overseas to limit the effect of harmonics on the electricity supply system, and how these limits impacted on the design of the new generation VSDs. It further examines the effect that advances in microprocessors and electronic power devices has had in the design of the new drive topology.read more

Five-Level Diode-Clamped PWM Converters Connected Back-to-Back for Motor Drives
N. Hatti,Y. Kondo,Hirofumi Akagi +2 more
TL;DR: Experimental waveforms show that the four split dc-capacitor voltages are well balanced in any operating conditions and that the total harmonic distortion values of the input line current and the output motor current are 3.9% and 3.5%, respectively.

Performance characteristics of five level diode clamped multilevel inverter for induction motor drives
TL;DR: The voltage and current harmonic values of the induction motor output were reduced by using the space vector PWM switching technique, a remedy for the voltage stabilizing problem which occurs during the implementation of split dc capacitors.
