摘要

合理设计多端口转换器(MPC)拓扑结构有助于克服多种可再生能源组合的困难。在本文中，从拓扑结构、工作原理、各种可靠性和总体效能方面对这些mpc进行了全面的分析。有两种主要类型的mpc，即非隔离型和隔离型mpc，它们以并联和串联方式耦合，作为多输入转换器。这些mpc可以为RES或BESS(电池储能系统)应用在一个或两个方向上流动负载功率。非隔离型mpc是近年来应用最为广泛的一种电路，但其存在电压增益小、隔离失效等缺点。隔离式MPC在输入功率级和输出功率级之间的隔离效果优于非隔离式MPC，但存在成本高、高频变压器体积大等缺点。本文介绍了一种高效电压调节器/电池储能系统(VR-BESS)，该系统是一种用于独立式光伏阵列的多端口DC-DC转换器。这种转换器的开关更少，更便宜，而且比同类产品更可靠。

A Comprehensive Review of Multi-Port DC/DC Converters for The Off-Grid System Integration with Renewable Energy Resources

Appropriate design of Multi-Port Converter (MPC) topology helps to overcome the difficulties of combining numerous renewable energy sources (RES). In this article, a comprehensive analysis of these MPCs in terms of their topologies, operating principles, various dependability, and overall efficacy is offered. There are two main types of MPCs which are non-isolated and isolated MPCs being coupled in parallel and series configurations to function as multi-input converters. These MPCs can flow the load power in one or both directions for the RES or BESS (battery energy storage system) applications. The non-isolated MPCs are most used in the latest years but they have some limitations such as small voltage gain, and failure in isolation. The isolated MPC is more effective than the non-isolated ones in terms of isolation between the input power stage and output but has some drawbacks such as the high cost, and large size of the high-frequency transformer (HFT). In this review paper, a high-efficiency voltage-regulator/battery energy storage system (VR-BESS) was presented as a multi-port DC-DC converter for the standalone PV (photovoltaic) array. This converter has fewer switches, is cheaper, and is more dependable than its counterparts.
