Dual Direct Matrix Converter-Based Drives With Enhanced Input Power Factor Control and Common-Mode Voltage Elimination

Year: 2025

Type: article

Abstract: The demand for high-efficiency, compact, and power-dense ac–ac conversion is driving renewed interest in matrix converters for industrial and renewable energy applications. This article introduces a novel input power factor (IPF) control strategy for a dual direct matrix converter (DMC)-based drive, enabling independent control of IPF while mitigating common-mode voltage (CMV) without additional hardware. Unlike conventional approaches that inherently constrain the reactive power control range, the proposed method extends IPF control to absolute maximum ratings, unlocking unprecedented flexibility in grid-interfacing applications. A fully decoupled approach to output voltage synthesis and IPF control is demonstrated by leveraging a generalized complex-domain model, ensuring optimal control across varying load conditions. Experimental validation is conducted on a dual DMC prototype, verifying the superior performance of the proposed method. The results highlight an expanded IPF control range and elimination of high-frequency CMV, positioning this methodology as a disruptive advancement in matrix converter technology.
