摘　　要：针对三相双有源桥电路在输入输出电压不匹配时效率较低的问题,本文提出了一种可变占空比三自由度稳态最优控制参数获取方法。首先采用分段时域分析方法建立一个模拟电路稳态模型,然后通过粒子群优化算法对控制参数进行预计算。结果显示,采用该方法计算出的控制参数可以在较大的输出功率范围内有效降低导通损耗,所获得的优化控制参数可用于辅助控制器的设计工作。Aiming at the problem of low efficiency of the three-phase dual active bridge circuit when the input and output voltages are mismatched,this paper proposes an optimal control parameter acquisition method of variable duty cycle three-degree-of-freedom steady-state.Firstly,a segmented time-domain method is used to establish a simulated circuit steady-state model by computer programming,and then the control parameters are pre-calculated through the particle swarm optimization algorithm.The results show that the control parameters calculated by this method can effectively reduce the conduction loss within a large output power range,and the obtained optimized control parameters can be used to assist in the design of the controller.
