The anticipated functionality of the single-stage, isolated AC-DC matrix converter involves catering to the versatile deployment requirements of diverse AC/DC systems. It is designed to facilitate bidirectional power conversion while ensuring electrical isolation. As a result of the current coupling phenomenon observed on the high-frequency link (HFL) transformer, conventional space vector modulation (SVM) and common dual-active-bridge-based (DAB-based) modulation techniques exhibit a relatively significant presence of harmonics in the power grid current. Conversely, more recent approaches significantly amplify the intricacy of modulation and control procedures. This paper presents a novel coordination strategy that integrates SVM and phase-shifted modulation (PSM). Furthermore, it thoroughly investigates the precise correlation between phase-shifted angles and the three-phase sinusoidal current. The proposed methodology effectively achieves power factor correction (PFC), minimizes total harmonic distortion (THD) in low power grid currents, and enables efficient bidirectional large power transmission.
