摘要
针对宽电压运行直流源接入直流电网的应用场景,文章提出一种基于T型三电平结构新型直流变换器,通过开关函数构造法推导该变换器在四自由度控制下的工作模式以及传输功率和电感电流均方根值的数学模型。
Aiming at the application scenario of connecting a wide-voltage DC source to the DC grid,a new DC converter based on T-type three-level structure is proposed in this paper.The working mode of the converter under the control of four degrees of freedom and the mathematical model of transmission power and inductor current root mean square value are derived by the construction of switching function method.
