“…Notice that one microcontroller, MCU 2 (red section), is assumed for the wind turbine emulation. On the other hand, it is worth mentioning that only one lowcost MCU, MCU 1 (blue section), is used for the implementation of the SVD modulation technique, 4-step switching strategy [37,38], converter input voltage, output current, velocity, and position measurements, besides MMPT and PMSG control algorithms. Accordingly, using a single processing device dramatically reduces the cost of implementing the WECS control subsystem since the MCU (F28379D LaunchPad) costs around $40.…”

This paper proposes the utilisation of the direct matrix converter (DMC) to regulate the power transfer between a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) and the power grid. By connecting the PMSG at the output terminals of the DMC, control actions are simplified, implementation is facilitated since fewer sensors are required, and a WECS with a more compact structure is achieved because it is not necessary to use a transformer to compensate for the DMC voltage ratio. The DMC operation is controlled by the singular value decomposition (SVD) modulation technique and the four‐step switching strategy. For power regulation, an maximum power point tracking (MPPT) algorithm based on the wind turbine power curves technique is used in conjunction with the field‐oriented control technique and a proportional‐integral compensator. In the developed prototype of the WECS described, modulation, MPPT, four‐step current switching, control algorithms, and signal measurements are implemented on a single microcontroller unit. Finally, experimental results demonstrate the effectiveness of the proposed WECS in regulating the transfer of active and reactive power adequately and simultaneously with the power grid.

“…As it is observed from the cited papers, there is a high demand for devices able to run algorithms in parallel because of the gate signals generation stage, and to the best of authors knowledge, an approach that addresses the complete control of the MC along with the commutation of the bidirectional power switches, in an on-chip solution based on a DSP or MCU has not been presented before. In [37], the gate signals generation is efficiently carried out by an MCU device. The implementation is based on the enhanced pulse width modulation peripheral (PWM) incorporated in the same chip.…”

In this paper, the implementation of a complete set of control algorithms for a three-phase Matrix Converter (MC) is addressed. The control algorithms are implemented on a single Microcontroller Unit (MCU) of the enhanced C2000 Delfino family of Texas Instruments (TI). By a suitable programming sequence, the MCU is capable of fully controlling the MC, which avoids the use of special hardware for assuring a reliable commutation process. The Singular Value Decomposition modulation (SVD) and the four-step current commutation technique, fundamental steps in this proposal, were implemented in the TMS320F28379D MCU device. The optimal algorithmic strategies and a proficient design allow a compact implementation in a single device. For validating this study, extensive numerical simulations were carried out, and an experimental prototype was efficiently implemented. Both kinds of results were discussed and analyzed to demonstrate the effectiveness of the proposed implementation. INDEX TERMS Matrix converter, singular value decomposition, microcontroller unit, ac-ac converter.

Reactive Power Transfer via Matrix Converter Controlled by the “One Periodical” Algorithm

The article describes the application of a straight forward energy converter, a multiphase matrix converter (MC), as part of a device, connected parallel to the power grid, and able to supply variable reactive power flow to the power system. The research performed by authors included the development of control procedures for a multiphase MC, based on a new approach and power system (application) requirements. The multiphase MC structure (6 × 6, 12 × 12) was used since the proposed control procedure creates output as the combination of input voltages. The increased number of phases decreases the order of harmonics in the MC converter similarly as in multilevel converters. This manuscript concentrates on the mathematical analysis of MC work under the “one periodical” algorithm and links it introduces in the power system. The previously developed, spatial-temporal mathematical model of the MC was limited to the dominant (first) harmonic and applied between the grid and reactive load. The results obtained from the analysis of the model showed that, for the applied control procedure (one periodical algorithm), the output voltage is built only from positive or negative sequences of input voltage. Three cases were recognized where the sign input power factor depends on input voltage and control sequence as well as on the value of control frequency. The effects of the model simulation were compared to those obtained from the MATLAB simulation and from the real laboratory 30 kVA-rated model. The main factors analyzed during this research include the expected value and distortion of input current and sign of reactive input power.
