摘要

The onboard chargers that are common on plug-in electric vehicles (PEVs) enable their owners to conveniently charge their cars at home or at any other location at any time of day. Despite their ability to provide rapid charging for lengthy journeys, off-board chargers are typically expensive, cumbersome, and require significant modifications to infrastructure. An ideal solution would be to create a compact, lightweight, and affordable device that incorporates the most advantageous features of both standard onboard and off-board chargers. This study proposes a single-phase integrated charger that utilizes a traction converter and driving machine of the PEV. The proposed charger design offers battery voltage and current management, as well as power factor modification, without the need for additional components. The primary feature of this charger is the implementation of a two-channel interleaved boost converter, which utilizes AC machine windings as interconnected inductors. The utilization of a Second Order Generalized Integrator (SOGI) control methodology ensures regulation of the charging current and voltage, resulting in a power factor close to unity. A 380-V, 3-phase, 6-pole PMSM is used to achieve the experimental results of a 3-kW hardware prototype. The experimental findings reveal a peak efficiency of 93.3%, accompanied by a 3.9% total harmonic distortion of the input AC current, and almost unity power factor.
