“…Here the filter components R, L f and C f present at the input side of the current source rectifier have a significant role in maintaining the DC link current constant and reducing the distortions at the transformer and CSR interface. The switching functions of the current source rectifier and voltage source inverter are adjusted to maintain the average DC side voltage and current constant [9].…”

“…This is also the case for any input voltage imbalancy, which results in presence of undesired harmonics in the input current and output voltage and reduces the maximum attainable balanced output voltage [1]- [3]. In the technical literature, a few methods have been proposed to mitigate the impact of unbalanced input voltages on the performance of the MC [1]- [11].…”

“…In [7], the gain of the MC is calculated based on the instantaneous values of the input voltages and the duty cycles of the switches are calculated using the indirect Space Vector Modulation (SVM) strategy. In [3], [9], a feedforward method, based on the instantaneous measurement of the input voltages is proposed.…”

“…However, under unbalanced input voltage conditions, the maximum attainable output voltage, that depends on the extent of the imbalancy in the input voltages, is reduced [1], [3], [11]. In this paper, a new modulation strategy that optimizes the performance of the MC when operating with a voltage gain greater than the maximum attainable one is developed.…”

In this paper, a new modulation strategy to control the 3x3 Matrix Converter (MC) under unbalanced input voltage conditions is proposed. The proposed strategy ensures that optimal performance of the MC is achieved over the entire range of operation, including the case when the converter operates with an output voltage greater than maximum attainable balanced output voltage under unbalance input voltage conditions. The implementation of the modulation strategy involves selection of the most appropriate switching states and calculation of the corresponding duty cycles to ensure that error in the output voltage and the input current is minimized. Performance of the proposed strategy is evaluated based on time-domain simulation studies in the MATLAB/Simulink software environment and experimentation on a scaled-down laboratory prototype.
