摘要

针对隔离式双有源桥DC/DC变换器采用单移相控制时会产生较大的电感电流有效值

导致电路损耗增加

功率转换效率降低.文章提出了三移相优化控制策略

该控制策略是基于广义三移相控制三种有效工作模式的功率和电感电流有效值

根据优化方程分别计算得到高中低功率范围内的最优控制结果

分析出在高功率范围内单移相控制是电感电流有效值最小的最优控制

而中低功率范围内三移相优化控制是电感电流有效值最小最优控制.最后通过在MATLAB上建立仿真模型

通过仿真结果验证了在中低功率范围内此三移相优化控制相比较于单移相控制减小了电感电流有效值

从而提高双有源桥DC/DC变换器的转换效率.

Abstract

When the single phase shift control is used for the isolated dual active bridge DC/DC converter

a large inductor current RMS value is generated

resulting in an increase in circuit loss and a decrease in power conversion efficiency. In this paper

a triple phase shift optimization control strategy is proposed. The control strategy is based on the generalized triple phase shift control of the three effective modes of power and inductor current RMS. The optimal control results in the high

medium and low power range are calculated according to the optimization equation. It is analyzed that the single phase shift control in the high power range is the optimal control with the minimum effective value of the inductor current

and the triple phase shift optimization control in the middle and low power range is the minimum optimal control of the effective value of the inductor current.Finally

by establishing a simulation model on MATLAB

it is verified by simulation results that the triple phase shift optimization control can reduce the effective value of the inductor current compared with the single phase shift control in the middle and low power range

and improve the dual active bridge DC/DC converter conversion efficiency.
