Reactive power compensation applications of matrix converter: a systemic review

Abstract

Matrix converters are bi-directional power electronic devices consisting of an array of solid-state switches directly connecting a source and load without an intermediate DC link. Historically, matrix converters have seen limited industrial adoption due to the complexity of their control mechanisms. However, in recent decades, matrix converter-based systems have emerged as viable alternatives for reactive power management because of the development of reliable and straightforward commutation methods. This paper provides a comprehensive analysis of matrix converter control strategies for reactive power compensation. Initially, an overview of matrix converter technology is provided. Then, Flexible Alternating Current Transmission System (FACTS) devices, renewable energy integration systems, and electric drives adopted in the last decade for reactive power compensation are discussed. The various ways these topologies have been employed for reactive power management are investigated, and an overview of direct and indirect matrix converter topologies is given. The application of control techniques such as model predictive control, space vector modulation, direct torque control, and others for reactive power compensation is then explored and their performance compared. Finally, directions for future research are identified. The analysis shows that matrix converter technology and control mechanisms have advanced substantially, demonstrating promise for wider industrial reactive power compensation applications. The continued development of cutting-edge matrix converter topologies and increasingly sophisticated control strategies will further broaden their reactive power compensation potential.
