In this study, the input filter design and dc-bus voltage control of ac motor drives utilizing low capacitance film capacitor are investigated. The dc-bus voltage instability problem arising due to the resonance between the dc-bus capacitor and circuit inductances is explained. A dimensioning algorithm of dc-bus filter components for stable operation is given. The simulation results of the low capacitance motor drives with and without dc-link inductor are provided to observe the stability of the dc-bus at different resonant frequencies. Voltage and current mode active stabilization methods found in literature aiming to actively damp the resonances in the dc-bus are analyzed and evaluated in the simulations for 2.2 kW and 37 kW rated induction motors driving constant torque load (CTL) and variable torque loads (VTL). Results are analyzed both in terms of input (line current) power quality and output (motor motion) quality.

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...
Performance Characteristics of the Reduced Common Mode Voltage Near State PWM Method Un, E.; Hava, Ahmet Masum (2009-07-01) The Near State PWM (NSPWM) method, which has low common mode voltage and low common mode current, is proposed for three-phase voltage source inverter drives. The method is described and its voltage linearity, output current ripple, DC bus current ripple, common mode voltage and output line-to-line pulse patterns are thoroughly studied and compared with classical PWM methods. The theory, simulation, and laboratory experiments illustrate that in the high modulation index operating range NSPWM has superior ove...
DC-link capacitor sizing of three-level neutral point clamped voltage source inverters for variable speed drives Ogan, Serhat Emir; Bostancı, Emine; Department of Electrical and Electronics Engineering (2021-12-13) A three-level neutral point clamped (NPC) voltage source inverter (VSI) topology can be advantageous in electric vehicles with a high DC-link voltage and a high switching frequency due to the flexibility in power switch selection. However, the potential oscillations in neutral point must be handled to guarantee an efficient operation of this topology. A bulky DC-link capacitor is not an option for EV applications; thus, the sizing of the DC-link capacitor considering the traction system characteristics is a...
Compatibility Issues Between the Filter and PWM Unit in Three-Phase AC Motor Drives Utilizing the Pure Sine Filter Configuration Cetin, N. Onur; Hava, Ahmet Masum (2011-11-01) Inserted between the inverter and the ac motor for the purpose of providing clean sinusoidal voltage at the motor terminals, the pure sine filter (PSF) involves common-mode and differential-mode suppression components. When using PSF in a motor drive and employing advanced pulsewidth modulation (PWM) techniques with discontinuous modulation waveforms, a large common-mode current may circulate through the inverter and the filter resulting in overcurrent stress in the inverter and significant acoustic noise i...
Performance characteristics of the reduced common mode voltage Near State PWM method Un, Emre; Hava, Ahmet Masum (2007-09-05) The Near State PWM (NSPWM) method, which has low common mode voltage/current is proposed for three-phase voltage source inverter drives. The method is described and its voltage linearity, output current ripple, DC bus current ripple, common mode voltage and output line-to-line pulse patterns are thoroughly studied and compared with classical PWM methods. The theory, simulation, and laboratory experiments illustrate that NSPWM has low common mode voltage, results in less common mode current, has low switchin...
