“…It is important to note that the proposed resonant control is slightly different from traditional methods, where the actual frequency is directly introduced in the control transfer function. This can be seen in [ 23 , 24 ], where the frequency is directly feed-forward as a variable parameter in the control loop. The main problem associated with this method of control is that the pole’s location needs to be changed as a function of the grid frequency.…”

Distorted voltage supplied as unbalanced and/or non-constant frequency can be found in weak grids, such as microgrids, or systems working in islanding mode. These kinds of systems are more sensitive under load changes. Particularly, an unbalanced voltage supply may be produced for large, single-phase loads. On the other hand, the connection/disconnection of high current loads may lead to important frequency variation, especially in weak grids where the short circuit current capacity is reduced. These conditions make the control of the power converter a more difficult task, because of the variations in the frequency and unbalancing. To address these issues, this paper proposes a resonant control algorithm to deal with variations in the voltage amplitude as well as grid frequency when a distorted power supply is considered. The frequency variation is an important drawback for resonant control because the resonance must be tuned at the grid frequency. This issue is overcome by using a variable sampling frequency in order to avoid re-tuning the controller parameters. On the other hand, under unbalanced conditions, the proposed method relaxes the phase with lower voltage amplitude by taking more power from the other phases in order to help the stability of the grid supply. To corroborate the mathematical analysis and the proposed control, a stability study is performed, including experimental and simulated results.

“…Indeed, the absence of large energy storage elements in the DC bus such as capacitors is the first real preference of such topology over the ordinary rectifier-inverter based topologies that have been used along the last decades in most of the industrial applications. Hence this converter topology allows obtaining less size and weight compared the conventional [3,5,6]. On the other side, the IMC can provide from the available AC three-phase power supply, AC output voltages with desired amplitude and frequency, theoretically with unlimited number of output phases.…”

“…On the other side, the IMC can provide from the available AC three-phase power supply, AC output voltages with desired amplitude and frequency, theoretically with unlimited number of output phases. Based on the control technique used, the harmonic content can be reduced in the output side of the IMC, where the input power factor can be also improved [5][6][7]. However, the harmonics content in the input side current is presenting a big challenge in the IMC topology, where the simple solution to handle this issue can be achieved by using an input LC filter as shown in Fig.…”

This paper deals with the Direct Torque Control (DTC) of Dual Indirect Matrix Converter (DIMC) feeding an open-end winding three-phase Induction Motor (IM). Indeed, the open-end winding topology allows overcoming the main problem of Common-Mode Voltage (CMV) which is responsible of presence of stresses in the motor winding in classical topologies, controlling separately the winding of the three-phases, reducing the voltage stress of the power electronics switches and to decreasing the voltage and current harmonics in each phase. The proposed Dual-output Indirect Matrix Converter generates 18 active voltage space vectors. Whereas, in the proposed algorithm presented in this paper to ensure the control of the proposed topology it is implemented only with two null vectors and six active voltage vectors for each output. It is based on same idea of the space vector pulse width modulation that is applied separately for both converters to ensure the control of their output voltages. Indeed, to ensure the required voltage at each winding the output voltage of the first matrix converter are generated normally and output voltage of the second matrix converter are generated with 180° phase shift. The obtained simulation results prove clearly the overall performance of the control of the studied drive system based on the proposed topology and its control algorithm which may be extended to other drive system application, especially in industrial application where more improved performances are required.
