A current-balancing strategy for a multileg interleaved DC/DC converter with a reduced number of current sensors for electric-vehicle chargers is proposed in this paper. There are imbalances between the leg currents of multileg DC/DC converters, which are caused by the difference between the leg impedances and the driver delay. Each of the leg current sensors must achieve current balancing. However, the conventional strategy is burdensome due to its high cost and volume. To mitigate these issues, the proposed balancing strategy effectively balances leg currents using fewer current sensors than the number of legs. The proposed strategy was verified by various simulation and experimental results.

电动汽车充电器多路交错式DC/DC转换器的电流平衡策略

本文提出了一种用于电动汽车充电器电流传感器数量减少的多路交错式 DC/DC 转换器的电流平衡策略。多腿 DC/DC 转换器的腿电流之间存在不平衡，这是由腿阻抗和驱动器延迟之间的差异引起的。每个支路电流传感器都必须实现电流平衡。然而，传统的策略由于其高成本和体积而繁重。为了缓解这些问题，所提出的平衡策略使用比支路数量更少的电流传感器有效地平衡支路电流。通过各种模拟和实验结果验证了所提出的策略。
