摘　　要：为了设计三半桥双向DC/DC变换器控制器参数,进一步提高变换器的性能,本文探讨了三半桥双向DC/DC变换器的模型。运用状态空间平均法,推导出了三半桥双向DC/DC变换器的状态空间平均方程。通过分析三半桥双向DC-DC变换器的小信号模型,推导出了变换器在Boost方向上控制-输出的开环传递函数。In order to design control system of triple half bridge bi-directional DC/DC converter, increase the performance of the converter, the paper probe into the modeling of triple half bridge bi-directional DC/DC converter, use the means of state space average, educe the state space average equation of triple half bridge bi-directional DC/DC converter. By analyze the small signal model of the half bridge bi-directional DC/ DC converter educe open loop switching function of the converter in the Boost operating mode.
