Objectives: Mirror therapy is a unique treatment with a touch of modality that is purported to improve the motor function of the affected limb in individuals with hemiplegia. Previous studies have focused on the neuro-physiological factors underlying the mechanism of the clinical effect of this technique. The present study aims to understand the mechanism using the rehabilitation method and neu...

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 is aimed to determine a general model for simulating the single and two-phase induction machines operation. The objective of this model is to predict motor performance parameters such as torque, and motor speed. The model includes representation of both main and auxiliary winding in stationary reference frame and also the effect of core losses and the saturation of the main flux path...

In the countryside of China, the main power supply mode is 220V single-phase power, which affects the widely application of three-phase agricultural appliances. What’s more, it means a block to the development of modern agriculture. However, frequency converter technique research is focused on three-phase high power frequency conversion technology at present, and there are very few achievements...

permanent magnet synchronous motors are efficient motors, which have widespread applications in electric industry due to their noticeable features. one of the interesting applications of such motors is in underwater vehicles. in these cases, reaching to minimum volume and high torque of the motor are the major concern. design optimization can enhance their merits considerably, thus reduce volum...

The paper presents a drive system consists of single-phase boost rectifier, space vector pulse width modulation (SVPWM) inverter, and three-phase induction motor. The single-phase boost rectifier is used to obtain near unity power factor and to reduce the harmonic distortion in the main supply. The SVPWM inverter is used to offer 15% increase in the output voltage and low output harmonic distor...

The main objective of this paper is to control the speed of an induction motor by changing the frequency using three level diode clamped multilevel inverter. To obtain high quality sinusoidal output voltage with reduced harmonics distortion, multicarrier PWM control scheme is proposed for diode clamped multilevel inverter. This method is implemented by changing the supply voltage and frequency ...

This paper deals with fault-tolerant control of five-phase induction motor (IM) drives under single-phase open. By exploiting a decoupled model for five-phase IM under fault, the indirect field-oriented control ensures that electromagnetic torque oscillations are reduced by particular magnitude ratio currents. The control techniques are developed by the third harmonic current injection, in orde...
