| 摘 要： | 研究了一种交错式双向直流变换器，该变换器工作在Boost方向时输入端进行交错并联，减小了输入电流纹波，输出端进行交错串联，提高了升压变比；工作在Buck方向时，输入端进行交错串联，输出端进行交错并联，因此该模式下具有较大的降压变比，同时减小了输出电流纹波。另外，在两种工作模式下，功率器件的电压应力都得到了降低。详细地分析了该变换器在两种模式下的工作原理及稳态特性，最后给出了实验结果以验证理论分析的正确性。

| Abstract: | An interleaved-type bidirectional DC/DC converter is studied in this paper. When this converter operates in Boost mode, the input is connected in parallel, which reduces the input current ripple; meanwhile, the output is connected in series so that a large voltage conversion ratio is achieved. When it operates in Buck mode, the input is connected in series while the output is connected in parallel, which extends the step-down ratio and minimize the output current ripple. Moreover, the voltage stresses of power devices can be reduced in both modes. The operation principles and steady-state characteristics of the proposed converter in both modes are analyzed in detail. Finally, experimental results were given to verify the theoretical analysis. |
