“…To obtain the model of the cell, the switches were considered as ideal. This was possible because the switching frequency was much greater than the modulation frequency [39,40], and with the switching constraint in Equation (2), the system dynamics were only related to the input and output filters. Figure 8 shows the diagram of the electrical equivalent .…”

This work presents a new methodology for designing input and output filters to be applied in a three-phase matrix converter, with an optimization problem solved by a metaheuristic algorithm. The algorithm determines the optimal values of the passive elements of the filters, taking as the fundamental performance criterion the response in magnitude. It is based on the resonant frequency, in order to eliminate the harmonics in the input currents and the output voltages produced by the bidirectional switching and disturbances in the power supply. These filters are implemented in a direct matrix converter using a Venturini-type modulation in open loop configuration. Other developments for this filter design have been carried out, but most of them were based on the conventional procedure of determining a random value for some element and then finding the magnitude of the remaining elements. That approach does not ensure the best dynamic filter response. The proposed design technique requires no initial elements, since all values are calculated by the metaheuristic algorithm.

Conventional approaches for voltage sag mitigation relies on voltage source inverters (VSIs). The bulky DC link electrolytic capacitors used in VSIs are reported to be the reason behind majority of failures of these converters. Absence of these electrolytic capacitors in Matrix Converter(MC) makes it a more reliable and compact alternative than the VSIs. This paper reports the performance of MCs as a sag mitigating device for linear loads.

“…The design, as well as the control and implementation of a three-phase GPU for aircraft servicing is presented in [18], [19] using a three-phase matrix converter where an output LC filter is considered at the output side. A four-leg matrix converter with an output LC filter is proposed to be used as a 400[Hz] aircraft ground power unit (AGPU) in [20], [21]. A resonant controller and a single loop repetitive voltage controller are considered to regulate the converter in order to obtain a fixed load frequency and voltage independent of the load present on the aircraft grid using optimal Venturini and SVM techniques.…”
