摘要

高频隔离双向双有源桥式(HFIB-DAB) DC-DC变换器是一种双向DC-DC变换器。介绍了一种混合功率调制方案，提高了整个功率范围内的效率。这种混合调制方案结合了两种不同类型的功率调制技术。在一定的功率调制水平下，DPS功率调制技术的效率更高，在此之后，射频功率调制技术的效率优于其他功率调制技术。在HFIB-DAB DC-DC变换器中，采用可重构谐振槽网络，针对给定的功率传输要求，提出了一种选择效率最高的转换方案。结果通过工作频率为50khz的4kw HFIB-DAB DC-DC变换器得到验证。它设计用于连接HFIB-DAB DC-DC转换器两侧的两个400V DC总线电压。利用MATLAB/Simulink软件包对其进行了验证，最大功率传输效率达到99.94%。

Hybrid Power Modulation Scheme for High Frequency Isolated Bidirectional Dual-Active-Bridge DC-DC Converter

High frequency isolated bidirectional dual-active-bridge (HFIB-DAB) DC-DC converter is a bidirectional DC-DC converter. A hybrid power modulation scheme is introduced, resulting in improved efficiency over complete power range. This proposed hybrid modulation scheme combines two different types of power modulation techniques. Up to certain level of power modulation, the DPS power modulation technique is more efficient and after that the efficient performance of RF power modulation technique supersedes over the other. A switch over provision is proposed to choose the most efficient one for a given power transfer requirement in the HFIB-DAB DC-DC converter by using the proposed reconfigurable resonant tank network. The results are verified by using 4 kW HFIB-DAB DC-DC converter operating at 50 kHz. It is designed to interface two 400V DC bus voltages on either side of the HFIB-DAB DC-DC converter. The validation is done by using MATLAB/Simulink package and a maximum power transfer efficiency of 99.94% is achieved.
