摘要：

DC-DC converters with high dynamic performance are attracting more and more attentions in industry and academia. The charge balance control (CBC) method enables the single-input dc-dc (SIDD) converter system to achieve optimal dynamic performance. In this article, the CBC method for the multiport converter is proposed, and the analogy and the innovative transplantation approach of the CBC from single-input systems to multi-input systems are developed. First, general steps and unified equations of the CBC for SIDD converter are summarized. Second, through analogy analysis, the CBC method is transplanted to a full-bridge three-port converter (FB-TPC) system to improve the dynamic performance under load step change. Third, through innovative transplantation, a CBC strategy based on magnetizing current three-stage regulation is proposed, achieving optimal dynamic performance for the FB-TPC system under power distribution step change. Experimental results on an FB-TPC verify the feasibility and effectiveness of the CBC methods for multiport converter and the transplantation method.
