摘要
为提高双有源全桥变换器的功率容量,各种模块化组合方式被相继提出.基于输入并联输出并联的模块化组合方式,首先建立了变换器的降阶小信号模型,然后分析了变换器相与相间的均流原理并给出了变换器的相固有参数估算方法和并联均流控制策略,最后基于仿真模型对所提出的控制方法的合理性和正确性进行了验证.
Abstract
In order to improve power capacity of dual active bridge converter,various modular combinations have been proposed.Based on modular combination of input parallel output parallel,this paper first establishes the reduced order small signal model of the converter,then analyzes the principle of current balance between phases of the converter,and obtains the estimation method of inherent phase parameters and parallel current sharing control strategy.Finally it verifies rationality and correctness of the proposed control method using simulation model.
