Medium voltage (MV) modular multilevel converters

s. 56-71 DOI: 10.17274/AEZ.2014.17.04

Abstract

The paper discusses selected issues related to the operation of medium voltage (MV) frequency converters in the MV variable speed drives, especially in applications with required galvanic separation from the network which is achieved by dc-dc converters with high frequency (> 5 kHz) transformers. Experimental results of the variable frequency electric submersible pump (ESP) drive using the developed MV frequency converter are presented

Keywords
