中文摘要:

双向变换器是微电网中的不可或缺的一部分,由DC/DC变换器将分布式电源、储能装置与负荷等构成的直流微电网,在未来供配电发展中会成为一种新的趋势。文中设计和制作了双向全桥DC/DC变换器,分析、计算和选择该变换器的功率器件及参数等,并进行了检验和参数调整。然后将该变换器其应用于直流微电网的锂电池组储能支路,实验结果表明,该双向全桥变换器能够正常工作,当直流微电网系统功率产生波动时,该储能支路能够与其他支路协调配合,稳定了直流母线电压,提高了直流微电网的稳定性。

英文摘要:

The bidirectional DC/DC converter plays a role in realizing the energy flow between the distributed power supply and the DC bus. By the DC/DC converter of distributed power supplies, energy storage devices and loads connected to the DC micro grid, has become an important model for future power supply. In this paper, the hardware of bidirectional full-bridge DC/DC converter is designed and fabricated, the power device parameters of converter are analyzed, calculated and selected, and the test and parameter adjustment are carried out. Then the bidirectional DC/DC converter is applied to the lithium-ion battery energy storage branch. The experimental results show that the bidirectional full-bridge DC/DC converter can increas.
