“…In Reference 49, the authors presented a compensation method for the capacitor current of the LC filter at the grid side in order to accurately realize unity power factor. The phase shift angle error at the grid side can be compensated by considering negative reference phase shift angle φ * , which is limited by the condition given in (36). In this case, the matrix converter reference input current will be lag behind grid voltage, hence grid current will be exactly in-phase with grid phase voltage.…”

Multi-phase converters for more than three-phase applications have become increasingly important topics due to their distinct advantages compared with the conventional three-phase converters. This paper proposes a modified PWM switching technique for direct AC-AC three-to-five phase matrix converter to realize output voltage waveform with low total harmonic distortion (THD) and reduce the total commutation number of its bidirectional power switches in each control period, simultaneously. In order to minimize the switching loss and reduce the voltage stress on all power switches of the matrix converter, the proposed PWM switching pattern prevents any state of direct commutation and switching between the maximum and minimum grid phase voltages. This in-turn enhances the converter durability and lifetime in addition to the power density. Also, the proposed PWM switching technique has the ability to fully control the load voltage waveform and its frequency to meet the reference values. In addition, it has the ability to control the three-phase grid currents to be sinusoidal waveforms and in-phase with grid voltages for unity power factor. Moreover, it enables voltage transfer ratio of 78.86% of the source input voltage. A laboratory prototype has been carried out in order to investigate the effectiveness of the proposed switching technique.

“…However, progressive research continuously aims at bridging these gaps. A step forward in making MCs more industry acceptable is the use of predictive control techniques [2, 3] in their control and modulation. Since the control of MCs is often associated with simultaneous attainment of numerous objectives, multi‐objective finite control set model predictive control (Mo‐FCS‐MPC) is naturally a popular choice.…”

Finite control set model predictive control (FCS-MPC) has lately received noteworthy attention in the control of power converters. Such converters have a finite number of switching states, which ensure a small sample space of predictions and minimum computational burden. Although unanimously popular in most converters, multi-objective FCS-MPC (Mo-FCS-MPC) is a particularly attractive choice in the control of matrix converters (MCs), as it enables attainment of multiple objectives with relative ease. Conventionally, a weighing factor-based approach is undertaken in the implementation of Mo-FCS-MPC wherein a cost-function is framed such that each of its constituent objectives, is assigned a relative weight according to its significance. However, the tuning of weights is empirical in nature and hence tedious. This study proposes an improvised technique for implementing Mo-FCS-MPC in MCs while simultaneously meeting a number of objectives such as load current, source current, and input power factor control. Sector information from space vectors of reference output voltages and reference input currents, coupled with a fuzzy decision-making criterion is used to make the final switching decision, hence eliminating the conventional weighing factor-based approach. The inclusion of space vector modulation into predictive control enhances the quality of both loads as well as source current waveforms.

“…The model predictive control (MPC) approach has emerged as an alternative to linear control techniques for power electronics topologies over the last decade [4]- [6]. MPC with imposed sinusoidal input currents is a technique for grid connected topologies such as direct matrix converters and current source rectifiers in order to obtain unity power factor operation.…”

This paper presents an imposed source current control technique based on model predictive control. This proposed control method can be used for battery charger applications fed from three-phase ac grid. The proposed MPC technique allows to charge the battery with a constant current or voltage as what is required for cyclic charge process of batteries. The proposed technique ensures unity input power factor operation for grid side. The single-objective cost function of the predictive control employs the error between supply current reference and supply current prediction and the switching state that makes this user defined cost function minimal is selected among the nine switching vector combinations of the current source rectifier so as to apply for next sampling interval. An active damping current term, that is predicted from the input filter capacitor voltage estimation is included in the cost function to alleviate the resonance phenomenon of input LC filter. The supply current references in phase with grid voltages are generated from grid voltages and the amplitude of this reference currents are generated from the charging requirements of the battery. The input filter model is used to predict the filter capacitor voltages at sampling intervals k and k+1 in order to eliminate sensor requirement for them. The control performance of proposed predictive controller is validated by simulation works in terms of steady-state behavior, dynamic response and supply current THD.
