This paper presents a comparative study on the Predictive Direct Torque Control method and the Indirect Space Vector Modulation Direct Torque Control method for a Doubly-Fed Induction Machine (DFIM) which its rotor is fed by an Indirect Matrix Converter (IMC). In Conventional DTC technique, good transient and steady-state performances are achieved but it presents a non constant switching freque...

The technology of direct AC/AC power conversion (Matrix converters) is gaining increasing interest in the scientific community, particularly for aerospace applications. In this paper a repetitive control system is proposed to regulate the output voltage of a four-leg matrix converter for a power supply application. The target application is a Ground Power Supply unit (GPU) for aircraft servicin...

This paper presents the experimental evaluation of reversed indirect matrix converter (MC) interfaced wind energy conversion system (WECS), where space vector pulse width modulation together with adaptive fuzzy logic control is effectively used to enhance the performance of system under various abnormal conditions like abrupt change in wind speed, disconnection from grid, misfire in the convert...

The matrix converter (MC) is a direct ac–ac power featuring high density and efficiency. However, the conventional MC (CMC) topologies require control complexity transistor capacity, hindering wide applications. An emerging topology (3CI-MC) based on third-harmonic current injection (3CI) reduces complexity, but requires more transistors complex clamping circuit. This article proposes trapezoid...

Open-end winding induction machines fed from two standard two-level voltage source inverters (VSI) provide an attractive arrangement for AC drives. An alternative approach is to use a dual output indirect matrix converter (IMC). It is well known that IMC provides fully bidirectional power flow operation, with small input size filter requirements. Whilst a standard IMC consists of an AC–DC matri...

Power Quality (PQ) parameters such as voltage RMS value, Total Harmonic Distortion (THD), and Power Factor (PF) are main topics to be considered in the connection of sensitive loads to the grid. In this paper, a Unified Power Quality Conditioner (UPQC) based on an Indirect Matrix Converter (IMC) is proposed to address some PQ issues as mitigation of voltage harmonics and compensation of sags an...

A new scheme to design the proportional integral (PI) type controller for speed control of a constant Volts/Hz (V/F) three phase induction motor drive employing a matrix converter has been presented. An approximate linear model of induction motor operating in constant Volts/Hz scheme is derived and a design example of a slip controller for a three phase motor is presented. Performance of the de...
