The regular sampling technique offers a feasible basis for the microprocessor-control of inverters in pulsewidth modulated (PWM) ac drives. An implementation of this technique is presented for the speed control of an induction motor in the frequency range 5-105 Hz. Hardware and software design principles are outlined and discussed for an 8-bit microprocessor. Spectral analyses of the sampling technique with a sinusoidal modulating function and with a third harmonic added to this function are derived, with emphasis on the fundamental and dominant components. Experimental and computed results are presented for the motor control in steadystate, and for transient current and speed in closed-loop operation, with excellent correlation.

Design and implementation of a voltage source converter based statcom for reactive power compensation and harmonic filtering Çetin, Alper; Ermiş, Muammer; Department of Electrical and Electronics Engineering (2007) In this thesis, design and implementation of a distribution-type, voltage source converter (VSC) based static synchronous compensator (D-STATCOM) having the simplest converter and coupling transformer topologies have been carried out. The VSC STATCOM is composed of a +/- 750 kVAr full-bridge VSC employing selective harmonic elimination technique, a low-pass input filter, and a /Y connected coupling transformer for connection to medium voltage bus. The power stage of VSC based STATCOM is composed of water-co...
A High-Performance PWM Algorithm for Common-Mode Voltage Reduction in Three-Phase Voltage Source Inverters Hava, Ahmet Masum (2011-07-01) A high-performance pulsewidth modulation (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 that 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...
Design of a ZVS QRC converter for educational test bench Şengüzel, İsmail; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2006) In this thesis, the conventional pulse-width modulated (PWM) and zero-voltage switching (ZVS) quasi-resonant buck converters are analyzed and a variable-frequency control technique is proposed to regulate the output voltage due to the immediate input line and load changes. The quasi-resonant technique provides favorable switching conditions for active switch to reduce switching losses and electromagnetic interference (EMI). The method is based on shaping the voltage across the active switch in quasisinusoid...
Design and implementation of advanced pulse width modulation techniques and passive filters for voltage source inverter driven three-phase ac motors Nebi, Onur Çetin; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2010) Advanced pulse width modulation (PWM) techniques such as space vector PWM, active zero state PWM, discontinuous PWM, and near state PWM methods are used in three-phase AC motor drives for the purpose of obtaining low PWM current ripple, wide voltage linearity range, and reduced common mode voltage (CMV). In some applications, a filter is inserted between the inverter and the motor for the purpose of reducing the stresses in the motor. The motor current PWM ripple components, terminal voltage overshoots, sha...
Design, Implementation and Operation of a New C-type 2nd Harmonic Filter for Electric Arc and Ladle Furnaces Gercek, Cem Ozgur; Ermiş, Muammer; Ertas, Arif; Kose, Kemal Nadir; Unsar, Ozgur (2010-10-07) In this research work, the transient overvoltage suppression capability and harmonic filtering performance of C-type 2nd harmonic filters are optimized by using two-stage damping resistors; one is permanently connected to the filter circuit, while the other one is switched on by back-to-back connected thyristors during furnace transformer and Harmonic Filter (HF) energization periods. However in conventional C-type 2nd HFs there is only one damping resistor, which is permanently connected to the filter circ...
