摘要

本文介绍了一种高增益双向DC-DC变换器。该转换器由具有连续输入电流的降压升压拓扑组成，随后是基于高增益开关电容的升压转换器[11]。改进后的变换器有六个开关和它们的主体二极管。开关的操作是这样的，三个开关需要从每侧操作的门脉冲。低电压侧电流纹波消除和低开关电压应力是该变换器的主要特点。与其他降压-升压变换器相比，该变换器在升压模式下的电压增益更多。为了验证改进后的变换器的有效性，进行了仿真研究。

A Nonisolated Bidirectional DC-DC Converter with Current Ripple Cancellation at a Selectable Duty Ratio

A high gain bidirectional DC-DC converter is described in this paper. This converter consist of a buck-boost topology which has continuous input current followed by a high gain switched-capacitor based boost converter [11]. The modified converter has six switches with their body diodes. The operation of switches is in such a way that three switches requires gate pulse from each side of operation. The current ripple cancellation at low voltage side and low switches voltage stress are the main feature of this modified converter. Compared to other buck-boost converters, the converter's voltage gain is more in boosting mode. The simulation study is carried out and presented for validation of the modified converter effectiveness.
