ABSTRACT
This manuscript proposes to improve the use of space vector modulation (SVM) AC-DC matrix converter and fuzzy logic controller (FLC) based type I type II switching method to diminish the ripple of DC in this environment. The SVM strategy can optimize the zero vector duty cycle. The Type I and Type II FLC can recognize the error and send the correct signal to identify the pulse. Battery Energy Storage System (BESS) technology is the forefront of power generation and proves to be the most efficient and cost-effective. The ripple current flowing to the battery during charging interacts with the internal resistance of the battery to generate heat (I2R losses). Therefore, excessive ripple current reduces the service life of the battery and requires a high-performance Alternating Current (AC)/Direct Current (DC) matrix converter topology to achieve high efficiency with low ripple current. The AC-DC matrix converter facilitates that the bi-directional interconnection between the utility grid and relatively minimum voltage DC source/load. AC-DC matrix converter generates minimum ripples at DC current and minimal THD at AC current for satisfying grid codes and DC source/load demands. The study also compares the performance of DC current ripple with Current source converter (CSC), Back to Back converter (BBC) and T1-T2 Fuzzy-logic-based switching system for enhanced AC/DC matrix converter. The simulation outcomes demonstrate that the proposed enhanced AC-DC matrix converter is more efficient to reduce ripples compared to the existing converters, and controls the power according to the current requirement. The efficiency of the proposed system achieves optimal result of power efficiency. The efficiency of the proposed system is 98%. Also the ripple factor DC link current of the proposed technique for 1mH is 96%, 1.6mH is 78% and 2.5mH is 60%.
