In this thesis the design, control, stability, input power quality, and motor drive performance of ac motor drives with front end three phase diode rectifiers utilizing low capacitance dc bus capacitor are investigated. Detailed computer simulations of conventional motor drives with diode rectifier front end utilizing high capacitance dc bus capacitor and the drives with low capacitance dc bus capacitor are conducted and the performances are compared. Performance evaluation of various active control methods found in previous studies aiming to provide the dc bus stability of drives with low capacitance dc bus capacitor are done at various load levels and types. Design recommendations are provided for the drives utilizing low capacitance dc bus capacitor.

Calculation of core losses of a six-phase induction motor with third harmonic current injection
Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
An FPA based BLDC motor control system
Uygur, Serdar; Güran, Hasan Cengiz; Department of Electrical and Electronics Engineering (2012)
In this thesis, position and current control systems for a brushless DC (Direct Current) motor are designed and integrated into one FPGA (Field Programmable Gate Array) chip. Experimental results are obtained by driving the brushless DC motors of Control Actuation System of a guided missile. Because of their high performance, brushless DC motors are widely used in Control Actuation Systems of guided missiles. In order to control the motor torque, current controller is designed and implemented in the FPGA. P...
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...
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...
Implementation of a vector controlled induction motor drive
Acar, Akın; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004)
High dynamic performance, which is obtained from dc motors, became achievable from induction motors with the recent advances in power semiconductors, digital signal processors and development in control techniques. By using field oriented control, torque and flux of the induction motors can be controlled independently as in dc motors. The control performance of field oriented induction motor drive greatly depends on the correct stator flux estimation. In this thesis voltage model is used for the flux estima...
