Rotating Phase Shedding for Interleaved DCDC Converter-Based EVs Fast DC Chargers

Mohammed A. Alharbi et al.

Summary: Fast DC chargers play a crucial role in the widespread adoption of electric vehicles by reducing charging time. However, the increasing variety in battery technology poses challenges for charger design. This article proposes a rotating phase-shedding control technique to evenly distribute the thermal stress among all phases, improving system reliability and efficiency. Through simulations and experiments, the proposed approach is shown to achieve a better thermal damage distribution compared to conventional phase shedding, ultimately extending the system's lifetime.
