摘要
研究一种双有源桥式双向DC-DC变换器的控制方法:三重移相控制。解决了单移相控制没有考虑到的有功功率由输入侧传向输出侧过程中,部分能量由输出侧传回输入侧,即回流功率的影响。提高了变换器传递能量的效率。本研究采用了基于傅里叶变换理论进行系统建模和基于瞬时功率积分的方法建立功率模型,并分析了相关的变换器功率特性。最后通过仿真验证了三重移相控制的优越性。
Research on a control method for the dual active bridge bi-directional dc-dc converter= triple-phase-shift control.Solve the problem which triple-phase-shift doesn＇t consider that in the process of the active power transferred from the input side to the output side, a part of energy will flow back to the input side.The efficiency of transmission energy of the converter is improved.This study adopts the theory of Fourier transform to model.In addition, the power model is established based on instantaneous power integration.Besides,the study also analyse the power characteristics of the converter.At last, terrify the superiority of the triple-phase-shift by simulation.
