摘要

为提高双有源桥DC-DC变换器的效率,提出一种基于双重移相控制的最小回流功率优化方案。针对双重移相的两种工作模式,分析推导各模式下的传输功率、回流功率及零电压开通（ZVS）特性,采用Karush Kuhn Tucker（KKT）条件法结合零电压开通特性求解实现回流功率最小化的最优移相比组合,由此提出最小回流功率优化方案及相应的控制策略。基于所提控制策略搭建实验样机,分析该方案的动态特性并对其与单移相控制、传统双重移相优化控制下的稳态特性包括回流功率、效率分析。所提优化控制的可行性和有效性在实验结果中得到了验证。

Abstract

A minimum backflow power optimization scheme to improve the efficiency based on dual phase shift control of dual active bridge DC-DC converter is proposed. Analyze and deduce the transmission power, backflow power, and zero voltage switching characteristics under each mode. By using the Karush Kuhn Tucker（KKT） condition method combined with zero voltage switching characteristics, the optimal shift ratio combination for minimizing backflow power is solved, and a minimum backflow power optimization scheme and control strategy are proposed. An experimental prototype is built based on the proposed control strategy. The dynamic characteristics of the scheme are analyzed, and the steady-state characteristics of the scheme are compared with single phase shift control and traditional dual phase shift optimization control, including backflow power and efficiency analysis. The feasibility and effectiveness of the proposed optimization control have been verified in the experimental results.
