摘要

电池储能系统广泛应用于可再生能源发电和电力运输系统。双向DC-DC转换器（bdc）是该系统的关键部件，可实现电池充电和放电模式下的双向功率流。bdc可分为隔离型和非隔离型。非隔离式bdc具有更小的体积、重量和功率损耗，适用于紧凑的结构而不需要电隔离。本文对非隔离式bdc进行了全面的文献综述，包括软开关、电流纹波减小、高电压增益和弹性技术。软开关以降低开关损耗和提高效率为目的，包括辅助电路和非辅助方法，如交错结构、相移调制、同步整流等。电流纹波的减少主要集中在电容回路配置、交错结构和基于耦合电感的方法上。电池是低压电源，bdc可以通过适当的电压增益将输出电压提高到应用所需的水平，而高电压增益技术包括基于电容的、基于磁性的、组合网络和混合结构。探索弹性，以确保在不利条件下可靠运行。这篇综述为开发更高效、可靠和高性能的bdc，满足现代能源系统不断变化的需求提供了有价值的见解。最后，对非分离bdc的未来研究方向进行了展望。

Design Criteria of Non-Isolated Bidirectional DC-DC Converters: A Review

Battery energy storage systems are widely used for renewable power generation and electric transportation systems. Bidirectional DC-DC converters (BDCs) are key components in such systems, enabling bidirectional power flow in battery charging and discharging modes. BDCs can be categorized into isolated and non-isolated. Non-isolated BDCs have lower volume, weight, and power losses, suitable for compact structures without needing galvanic isolation. In this paper, a comprehensive literature review is conducted for non-isolated BDCs, covering soft switching, current ripple reduction, high voltage gain and resiliency techniques. Soft switching aims to reduce switching losses and improve efficiency, including auxiliary circuits and non-auxiliary methods, such as interleaved structures, phase-shift modulation, and synchronous rectification. Current ripple reduction focuses on capacitive loop configurations, interleaved structures, and coupled inductor-based methods. Batteries are low-voltage power sources, BDCs can increase the output voltage to a level required by the applications through an appropriate voltage gain, and high voltage gain techniques include capacitor-based, magnetic-based, and combined networks, and mixed structures. Resiliency is explored to ensure reliable operations under adverse conditions. This review provides valuable insights into developing more efficient, reliable, and high-performance BDCs, addressing the evolving demands of modern energy systems. Future research directions in non-isolated BDCs are recommended in this paper.
