Motor current signature analysis (NICSA) provides a method for non-intrusive and continuous monitoring of motors in many applications. Initially, the fast Fourier transform (FFT) was the main signal processing method used in such analysis. Recently, wavelet packet decomposition (WPD) has become popular in such applications. The second approach gives better results in the case of non-stationary signals but it has much higher computational complexity limiting its use with real time power quality monitoring devices. Use of four-channel FIR cosine-modulated filter banks is proposed in this study to provide lower computational complexity.

A unity power factor buck type PWM rectifier for medium/high power DC motor drive applications
Bilgin, HF; Kose, KN; Zenginobuz, G; Ermiş, Muammer; Nalcaci, E; Cadirci, I; Kose, H (2000-10-04)
This paper describes the application of a single stage unity pf buck type PWM rectifier to medium and high power variable speed dc motor drives. The advantages of the developed system are low harmonic distortion in ac supply currents (comply with IEEE Std. 519 and IEC 555), nearly unity pf over a wide operating shaft speed range, nearly level armature -current and -voltage waveforms. These properties of output voltage and current quantities of the converter eliminate entirely any failure risk in current com...
A High Performance PWM Algorithm for Common Mode Voltage Reduction in Three-phase Voltage Source Inverters
Uen, Emre; Hava, Ahmet Masum (2008-06-19)
A high performance PWM algorithm with reduced common mode voltage (CMV) and satisfactory overall performance is proposed for three-phase PWM inverter drives. The algorithm combines the near state PWM (NSPWM) method which has superior overall performance characteristics at high modulation index and MAZSPWM, a modified form of the active zero state PWM method (AZSPWM1), which is suitable for low modulation index range of operation. Since AZSPWM1 has line-to-line voltage pulse reversals with small zero-voltage...
Current source converter based STATCOM: Operating principles, design and field performance
Bilgin, H. F.; Ermiş, Muammer (2011-02-01)
This paper describes the operating principles, design and field performance of two-level, three-leg device commutated current source converter (CSC) topology based Static Synchronous Compensator (STATCOM), which is developed for medium voltage industry applications. In the paper, the relationship between the reactive power and the control variables is obtained, harmonic minimization techniques applicable to CSC are investigated, and then Selective Harmonic Elimination Technique is applied for the eliminatio...
Adaptive control of DC link current in current source converter based STATCOM for improving its power losses
Karaduman, Ferdi; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2012)
In conventional three-phase PWM (Pulse Width Modulation) current source converter based STATCOM (Static Synchronous Compensator) applications, DC link current is kept constant at a predefined value and the reactive power of STATCOM is controlled by varying modulation index. This control strategy causes unnecessary power losses especially when the reactive power of STATCOM is low. For this purpose, in order to reduce the active power drawn by STATCOM, the modulation index can be maximized by adjusting DC lin...
Investigation on Series Active Filter Compensated High Power Grid-Connected Voltage Source Inverters with LCL Filter
Usluer, S. Nadir; Hava, Ahmet Masum (2014-09-18)
This paper deals with Series Active Filter (SAF) based damping methods for the LCL filters of three-phase, grid connected, low voltage, high power Voltage Source Inverters (VSIs). The inherent resonance problem of LCL filters is damped via passive or active damping methods. Passive damping methods employing damping resistors create significant power losses reducing the overall system's efficiency for high power inverters. Active damping methods, on the other hand, are not applicable due to inverter's limite...
