Abstract: This paper presents a new direct analyticalderivation of low frequency harmonics introduced byvoltage source inverters non-linearities in PMSM drives.The proposed voltage drops model is robust and requiresfewer calculations than time-based models, and has provento accurately estimate the experimental voltage drops forSiC based inverter output waveforms. Furthermore, ithas been extensively validated experimentally and offersan analytical tool to precisely estimate the voltage dropsintroduced by the inverter non-linearities.

   Extended Linear Modulation Based Full Bridge Modular Multilevel Converter for Adjustable Speed Drives
By Nageswara Rao KARAKA, Poornachandra Rao NALLAMATTI, Anshuman SHUKLA [View]
[Download]

Abstract: The modular multilevel converters (MMC) are gaining popularity for medium voltage adjustable speed drives (ASD) due to modularity and efficiency. However, the MMC drives experiences high ripple voltage in submodule (SM) capacitor during low speed operation. In this paper, an extended linear modulation range operation of full-bridge (FB) submodule based MMC drives is proposed to reduce the ripple voltage. In addition, comparative study of the minimum energy storage requirement for the proposed drive and conventional MMC drive is also presented. This analysis includes the motor operating parameters (power factor, current, etc.,) variation due to the load torque profile is also considered for its effective evaluation. The detailed analysis reveals that the capacitor voltage ripple is significantly lesser with extended linear modulation when compared to the conventional modulation, making FB-MMC as apotential candidate for drives. The effectiveness of the proposed operation scheme is validated usingPSCAD simulation study.

   Loadability of Converter-fed Induction Machine
By Hannu KÄRKKÄINEN, Pia LINDH, Lassi AARNIOVUORI, Matias TIIHONEN, Markku NIEMELÄ [View]
[Download]

Abstract: The main dimensioning principle of an electrical machine is the temperature rise that is directly related to losses of the machine. When PWM-supply is used, an additional high frequency switching frequency dependent loss component is induced. Here, the actual loadability of a converter-fed 15-kW induction motor is experimentally tested using different switching frequencies.

   Parallel Hybrid Converter-Based Adjustable Speed Drives Using Third Harmonic Voltage Injection Technique
By Nageswara Rao KARAKA, Ibhan Chand RATH, Anshuman SHUKLA [View]
[Download]

Abstract: The modular multilevel converter (MMC) is widely preferred in medium voltage adjustable speed drives (ASD) due to its modularity and efficiency. However, the MMC drives face high ripple voltage across the submodule (SM) capacitor during low-speed operation and require high energy storage. A parallel hybrid converter (PHC) based ASD is a potential alternative to MMC in terms of energy storage requirement. In addition, SMs ripple voltage of PHC drive is independent of operating speed. However, the PHC has a strong coupling between the ac side voltage and dc side voltage. In order to achieve the decoupled and variable ac voltage for ASD a third harmonic voltage injection (THVI) technique is proposed. The performance of the proposed technique is verified using the simulation study and further validated using the experimental prototype.

   Power losses Analysis in Frequency Domain of IPMSM Drive fed by Cascaded H-Bridge Multilevel Inverter

Abstract: Power losses analysis of an IPMSM drive is a challenging task, especially, when multilevel inverters are employed. This study focuses on an IPMSM drive fed by a Cascaded H-Bridges Multilevel Inverter (CHBMI) controlled by MC-PWM strategies, employing a frequency domain power analysis approach based on Discrete Fourier Transform (DFT).

   Reduction of circulating bearing currents in dependence of nanocrystalline common-mode current ring cores
By Martin WEICKER, Hans-Joachim POESS [View]
[Download]

Abstract: According to inverter-induced bearing currents a method is introduced to estimate the maximum bearing current limit from the bearing size for a safe long-term operation. In addition, this method is specified to calculate the maximum common-mode current level at the inverter output for harmless high frequency circulating bearing currents at totally enclosed, fan-cooled drives.
