About voltage total harmonic distortion for single- and three-phase multilevel inverters [Article]

Ruderman, Alexander (Nazarbayev University School of Engineering and Digital Sciences, 2015-03)

Many recent multilevel inverter papers end up with voltage total harmonic distortion (THD) values obtained from numerical voltage spectrum calculations (measurements). Motivated by IEEE Standard 519, a part of the multilevel ...
Design, Modeling And Analysis Of A New Dual Input-Output Switched Capacitor Converter

Zhaikhan, Ainur; Subburaj, Vivekanandan; Jena, Debashisha; Perumal, Parthiban; Ruderman, Alexander (IEEE Region 10 Conference (TENCON), Malaysia, 2017-11-05)

A new dual-input and dual-output switched capacitor (SC) converter is designed to operate with two independent voltage sources that provides two different output voltages. The only converter generates 32 voltage conversion ...
Discussion on 'effect of multilevel inverter supply on core losses in magnetic materials and electrical machines' [Article]

Ruderman, Alexander (Institute of Electrical and Electronics Engineers, 2015-11)

Presents a discussion on the following paper, “Electrical machine PWM loss evaluation basics (Ruderman, A. and Welch,R.) in Proc. Int. Conf. Energy Efficiency Motor Driven Syst.,Sep. 2005, vol. 1, pp. 58-68.
Reconfigurable Multiphase Switched Capacitor Converters Based on Non-Binary Numeral Systems: Ternary Case

Zhaikhan, Ainur; Kypshakpayev, Yerden; Ruderman, Alexander (IEEE, Brasov, Romania, 2017-05-25)

Multiphase Switched Capacitor Converters (SCC) recently gained attention due to their ability to generate different voltage Target Ratios (TR). One of the reconfigurable multiphase SCC topologies is a binary one. For ...
SCC Equivalent Resistance: the Relationship for Complementary Buck and Boost and Accurate Calculation for 2-Phase Converters

Mustafa, Yerzhan; Zhaikhan, Ainur; Ruderman, Alexander (IEEE, Budapest, Hungary, 2018-08-26)

This paper makes the following contributions to Switched Capacitor Converter (SCC) equivalent (output) resistance analysis. First, it suggests the relationship between equivalent resistances of complementary buck and ...
