An Efficient Carrier-Based Modulation Strategy for Five-Leg Indirect Matrix Converters to Drive Open-End Loads with Zero Common-Mode Voltage

Improved DTC-SVM Based on Input-Output Feedback Linearization Technique Applied on DOEWIM Powered by Two Dual Indirect Matrix Converters

“…It consists of an input stage and two output stages, which allow ensuring a three-phase voltage supply at both outputs. This new structure is obtained by both maintaining the input stage as in the conventional structure and making the output stage consist of two independent voltage inverters, which are connected to the same DC link voltage [23,24,41]. This topology will be used in this paper to power the studied DOEWIM drive from both sides of the six phases' windings independently, in which the motor stator is fed by four three-phase voltages systems, as shown in Figure 2.…”

“…Indeed, since the introduction of MC in electric motor driving, different modulation strategies have been proposed; initially, the scalar modulations were adopted but they demonstrated several defects, notably those associated with a lack of output voltage waveform quality and limited transformation ration. It was therefore necessary to use other advanced control techniques, such as the space vector modulation (SVM), in order to eliminate the aforementioned problems caused by the conventional scalar-based control technique [22][23][24].…”
