For the past two decades, Brushless DC motor has become more efficient and robust motor in industrial applications due to their simplicity in structure, reliability, good mechanical properties. The absence of brushes features these motors similar to AC motors whereas their speed performance is nearly equal to that of the DC motors. Thus the combined advantages of AC and DC motors make these mot...

The main purpose of this paper is to describe the four-switch brushless dc (BLDC) motor drive for varoius applications. For effective utilization of the developed system, a novel direct current controlled pulse width modulation scheme is designed and implemented to produce the desired dynamic and static speed–torque characteristics. Also, t h e feasibility of the four-switch converter. Keywords...

This paper presents a power factor correction (PFC) based canonical switching cell (CSC) converter-fed brushless dc motor (BLDCM) drive for low-power household applications. The speed of BLDCM is controlled by varying the dc-bus voltage of voltage source inverter (VSI). The BLDCM is electronically commutated for reduced switching losses in VSI due to low-frequency switching. A front-end CSC con...

This paper presents a novel approach for determination of optimum values of Kp, Ki and Kd for design of controllers such as PD, PI & PID for enhancement of performance parameters of Permanent Magnet Direct Current (PMDC) Motor drives using IGBT based chopper in MATLAB/SIMULINK toolbox environments. The effectiveness of proposed novel approach has been presented so that the better performance pa...

Sensitive equipment and non-linear loads are now more common in both the industrial/commercial sectors and the domestic environment. Because of this a heightened awareness of power quality is developing among electricity users. Therefore, power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Continuous variation of single-phase loads ...

This paper presents an indirect matrix converter (IMC) topology for hybrid electric vehicle (HEV) application with three-phase and single-phase outputs. The HEV includes mechanical, electrical, control, and electrochemical systems among others. In the mechanical system, a traction motor and a compressor motor are used to drive the HEV. The traction motor and the compressor motor are usually ope...

This paper deals with a comparative analysis of various converter topologies for Power Factor Correction (PFC) in BLDC motor drives. A power factor corrected converter is required for improving power quality at the AC mains of an inverter fed BLDC motor drive. Conventionally, the BLDC motor is fed by a diode bridge rectifier (DBR) which results in highly distorted supply current and a poor powe...

In high power high voltage application BLDC motor are widely used because of high efficiency, simple construction, low cost less maintenance and high torque or high output power per unit volume. For driving the BLDC motor we required inverter. PWM inverter which gives good performance. In two level inverter there is a problem of harmonics distortion, lower electromagnetic interference, high DC ...
