Design and Control of a Unified Multiport Matrix Converter for Integrated Electric Vehicle Charging, Propulsion and Regenerative Energy Management

Abstract The increasing demand for electric vehicles (EVs) has accelerated research toward compact, efficient, and multifunctional power electronic converters capable of integrating charging and propulsion functions within a common hardware platform. Conventional EV architectures generally employ separate converters for onboard charging, traction drive, and regenerative braking [2], [14], resulting in increased component count, system complexity, and reduced power density. This paper proposes a unified multiport matrix converter architecture that combines a Direct Matrix Converter (DMC) with an isolated Phase Shift Full Bridge (PSFB) converter to achieve AC charging, DC fast charging, propulsion, and regenerative braking using a single integrated power conversion system. The proposed topology eliminates the bulky intermediate DC-link capacitor while enabling direct AC-to-AC power conversion with galvanic isolation through a high-frequency transformer. Bidirectional power flow capability enables efficient energy transfer during both charging and regenerative operating conditions. A digital control strategy based on Space Vector Pulse Width Modulation (SVPWM) and Sinusoidal Pulse Width Modulation (SPWM) is employed to regulate converter operation under different operating modes. The proposed architecture is validated through MATLAB/Simulink modelling, and a low-power hardware prototype based on an STM32F407 microcontroller is proposed for future implementation. The proposed system aims to reduce converter count, improve power density, and provide a flexible solution for next-generation electric vehicle powertrain applications.
