| Abstract: | The rapid electrification of road transportation demands efficient and reliable power conversion solutions for high-performance electric vehicle (EV) drive systems. This paper presents the modelling and simulation of an Insulated Gate Bipolar Transistor (IGBT)-based Active Front-End (AFE) rectifier for 270 V DC bus applications in EVs. The proposed system regulates the DC-link voltage while maintaining near-sinusoidal input currents and unity power factor. The AFE rectifier is modelled in the synchronous � �𝑞reference frame and controlled using cascaded voltage and current loops implemented in MATLAB/Simulink. Proportional–Integral (PI) controllers are designed via closed-loop transfer function analysis to achieve fast transient response and robustness against line and load variations. Simulation studies under steady-state, dynamic, and transient conditions demonstrate effective harmonic suppression, stable DC-link voltage, and improved power quality. The results indicate that the proposed AFE rectifier control scheme is a practical solution for 270 V DC bus regulation, supporting the integration of onboard chargers, battery packs, and traction motor drives in electric vehicles. |
| Description: | The rapid shift toward sustainable transportation is driving increased demand for highly efficient and reliable electrical power systems in electric vehicles (EVs) and hybrid electric vehicles (HEVs). At the heart of these systems is the power conversion stage, which governs energy exchange among the grid, the battery storage system, and the motor drive [1]. Selecting an appropriate DC-link voltage is essential for maintaining power quality, optimizing efficiency, and ensuring overall system stability across diverse operating conditions. Early generations of EV power electronic systems primarily employed low-voltage (12/48V) architectures and unidirectional converters dedicated to auxiliary loads, whereas the increasing requirements for traction power and onboard charging have shifted research focus toward higher DC-link voltages and bidirectional converter topologies [2]. Within this technological evolution, voltage-source Active Front-End (AFE) rectifiers have become a key interface for regulated DC buses, as they provide near-unity power factor, low input harmonic distortion, and regenerative capability, all of which closely match the demands of EV charging and drive-cycle operation [3,4]. A regulated 270 V DC bus has consequently emerged as a promising solution, particularly for medium voltage EV platforms, heavy-duty vehicles, and specialized applications such as electric buses and construction machinery [5]. |
