This paper proposes a new neutral point potential control technique for the neutral-point-clamped three-level inverter. Utilizing the phase current polarity information, this technique distributes the redundant voltage vectors in a manner to obtain stable neutral point voltage under all operating conditions including the zero-power-factor condition. Detailed analysis and computer simulations show the superiority of the proposed method. The feasibility of the proposed method has been proven via laboratory experiments.


High-Performance Harmonic Isolation and Load Voltage Regulation of the Three-Phase Series Active Filter Utilizing the Waveform Reconstruction Method
Senturk, Osman S.; Hava, Ahmet Masum (Institute of Electrical and Electronics Engineers (IEEE), 2009-11-01)
This paper develops a waveform reconstruction method (WRM) for high accuracy and bandwidth signal decomposition of voltage-harmonic-type three-phase diode rectifier load voltage into its harmonic and fundamental components, which are utilized in the series active filter (SAF) control algorithms. The SAF-compensated system utilizing WRM provides high-performance load harmonic voltage isolation and load voltage regulation at steady-state and during transients compared to the system utilizing the synchronous r...

Beyaz, Mustafa Ilker; Habibiabad, Sahar; Yildiz, Hamza; Goreke, Utku; Azgın, Kıvanç (Institute of Electrical and Electronics Engineers (IEEE), 2019-06-01)
This paper reports a compact magnetic transducer developed for generating electrical power from respiration. The device incorporates a side-drive turbine rotor with embedded permanent magnets and two stators, integrated into a poly(methyl methacrylate) (PMMA) package for actuation. The novelty and advantage of the design lies in almost full use of the available turbine volume together with two stators for both mechanical and electrical transduction, which leads to high rotational speeds and high voltage gen...
In-flight calibration of pico satellite attitude sensors via unscented kalman filter
Söken, Halil Ersin (Pleiades Publishing Ltd, 2011-07-01)
In this paper an Unscented Kalman filter based procedure is proposed for the bias estimation of attitude sensors of a pico satellite. Three axis magnetometers and the rate gyros are used as attitude sensors. At the initial phase, biases of three orthogonally located magnetometers are estimated as well as the attitude and attitude rates of the satellite. During initial period after the orbit injection, gyro measurements are accepted as bias free, since the precise gyros are working accurately and the accumul...
New spectral decomposition based approach for flicker evaluation of electric arc furnaces
Koese, N.; Salor, Oe. (Institution of Engineering and Technology (IET), 2009-04-01)
A spectral decomposition-based approach is proposed to estimate the light flicker caused by electrical arc furnaces (EAFs) where the system frequency deviates significantly due to the EAF operation. Analytical expressions of the instantaneous light flicker sensation are obtained beginning from a voltage waveform and these expressions are used to obtain a flicker estimation method based on the IEC flickermeter. In the proposed method, the leakage effect of the FFT algorithm due to fundamental frequency varia...
A Generalized Scalar PWM Approach With Easy Implementation Features for Three-Phase, Three-Wire Voltage-Source Inverters
Hava, Ahmet Masum (Institute of Electrical and Electronics Engineers (IEEE), 2011-05-01)
The generalized scalar pulse width modulation (PWM) approach, which unites the conventional PWM methods and most recently developed reduced common mode voltage PWM methods under one umbrella, is established. Through a detailed example, the procedure to generate the pulse patterns of these PWM methods via the generalized scalar PWM approach is illustrated. With this approach, it becomes an easy task to program the pulse patterns of various high performance PWM methods and benefit from their performance in mo...
