Topologies, Control Algorithms and Applications of Bidirectional DC-DC Converters

Given the increasing worries surrounding the impact of fuels, nations are now shifting towards sustainable energy production options through the utilization of renewable energy sources. In tandem with advancements in electric vehicle technology, the automotive production market is moving towards the electrification of transportation, contributing to cleaner cities. The integration of renewable sources, batteries, and electric vehicles into the grid leads to the utilization of bidirectional DC-DC converters to secure a two-way power flow. These converters come in various topologies and employ different control techniques based on their application domains. In this review paper, a thorough analysis is conducted concerning the advantages, limitations, and applications of various topologies of DC-DC bidirectional converters. The bidirectional DC-DC converters’ main classifications are the isolated and non-isolated types. Within these categories, various topologies are compared. In addition, this review discusses novel topologies and emphasizes their contributions to the existing ones. Finally, an investigation is made into different control strategies utilized in the DC-DC bidirectional converters. This review aims to assist researchers by examining different configurations of DC-DC bidirectional converters. This will serve as a basis for comparing new designs or selecting the most suitable converter for a particular application.
