This paper presents an original study on the generated torque ripples of phase commutation in the Four-Switch, Three-Phase Inverter (FSTPI) Brushless DC (BLDC) motor drive which is suitable for low cost applications. Analytic values of torque ripple and commutation duration are obtained for different operation conditions. Moreover, limitation on the speed range operation caused from splitti...

High power factor, high frequency single stage single switch resonant inverter for the application of high frequency applications is presented in this paper. The power circuit is designed with a power factor corrector with single-switch current-fed high frequency resonant inverter. Number of switches used in conventional ballast circuits is reduced in single switch approach. SEPIC (Single ended...

this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...

This paper gives the theory and experimental results for a current-source parallel-resonant inverter employed for induction heating. The analysis is performed in the frequency domain using Fourier series techniques to predict output power, efficiency, dc-to-ac voltage transfer function, and component voltage and current stresses. The inverter consists of four switches, a large choke inductor, a...

Inverters designed using reduced active semiconductor devices can be of interest to the industry because of their lower cost and enhanced reliability linked to their less complex gating and control circuitries. In this paper a four switch three phase b-4 topology for the grid connected application in an effort to reduce the cost of the inverter is investigated. Admittedly, this topology warrant...

Direct Torque Control of induction motor fed drives has become popular and widely used in industries due to fast and good torque response. Induction motors (IM) are simple in construction and are less sensitive to the motor parameters compared to other vector control methods. A new torque and flux control scheme called the direct torque control (DTC) has been introduced for induction motors. In...
