Traditionally electrical drives and uninterruptable power supplies generate pulse width modulated outputs. Harmonic content of such waveforms are known to cause problems. Therefore, it is worthwhile to investigate 3-phase sinus output topologies, which can compete with traditional inverter topologies, regarding performance and cost. In this paper, first some topologies for producing single-phase sinus output are reviewed. Then, the possibility of using these single-phase units for producing 3-phase output is investigated. Finally, the findings are evaluated and the course for further investigation is identified.

Performance analysis and comparison of reduced common mode voltage PWM and standard PWM techniques for three-phase voltage source inverters Un, E; Hava, Ahmet Masum (2006-03-23) This paper investigates the performance characteristics of the reduced common mode voltage (RCMV) PWM methods for three phase voltage source inverters and provides a comparison with the standard PWM methods. PWM methods are reviewed and their pulse patterns and common mode voltage patterns illustrated. The AC output current ripple, DC link input current ripple, and output voltage linearity characteristics of each modulation method are thoroughly investigated by analytical methods and simulations. The analys...
Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30) In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
DC Link Capacitor Optimization for Integrated Modular Motor Drives Ugur, Mesut; Keysan, Ozan (2017-06-21) In this paper, selection of optimum DC link capacitor for Integrated Modular Motor Drives (IMMD) is presented. First, a review of IMMD technologies is given and current research and future prospects are studied. Inverter topologies and gate drive techniques are evaluated in terms of DC link performance. The urge for volume reduction in IMMD poses a challenge for the selection of optimum DC link capacitor. DC Link capacitor types are discussed and critical aspects in selecting the DC links capacitor are list...
A Proposal for Improving Efficiency of Inverter Driven Electrical Motors Ertan, Hulusi Bülent (2011-07-28) Conventional inverter output has PWM output. This pulsed output waveform reduces insulation life time, contributes to quick degradation of the bearings and also is often source of acoustic noise. Furthermore, losses of PWM inverter-driven motors increase. In this paper a novel topology is proposed which is capable of generating a sinusoidal waveform, with low harmonic distortion. If the proposed method is used for driving motors, motor efficiency increases due to reduced losses and lifetime of the motor may...
Fault Tolerance Capabilities of Three, Four and Six-Phase Configurations of a 24 Slot Modular PMSM Bayazıt, Göksenin Hande; Keysan, Ozan (2019-07-01) In this study, fault tolerance and redundancy capabilities of different phase and winding configurations of an Integrated Modular Motor Drive (IMMD) system are investigated. This is made possible by manipulating gate drive signals of the inverter and phase connections. Three and four phase connections as well as symmetric and asymmetric six-phase topologies are described. Control strategies and redundancy possibilities of these different topologies under an open circuit fault condition are examined in MATLA...
