Simulation of AC/ AC Converter using Single Phase Matrix Converter for Wave Energy Converter

Matrix converter applications in the power electronics field eliminate the common practice of reactive power storage in the system. Due to its universal converter applicability, the Single Phase Matrix Converter (SPMC) is among the most widely used matrix converter configurations. Operating as a universal converter means that the SPMC can be used as a frequency changer, an inverter, a rectifier, and a chopper. The SPMC topology consists of four bidirectional switches that allow reverse blocking and bidirectional current flow. This paper presents the implementation of SPMC as an AC/AC converter with passive load conditions. The output of SPMC is synthesized using the Sinusoidal Pulse Width Modulation (SPWM) technique to calculate the switch duty ratio. The modelling and simulation of SPMC are carried out using MATLAB/Simulink software, and the results are discussed. Further testing was conducted with the input generated from a point absorber wave energy converter simulated in ANSYS to validate the ability of the SPMC as an AC/AC converter model.
