摘要

研究了一种新型的具有双向能量流的多端口转换器,用于低压大电流汽车能源网。给出了一个为14v / 42v汽车能源网设计的三端口转换器的例子,并提供了连接双层电容器的可能性,以减轻电池过大的电流压力并稳定能源网电压。所提出的三端口转换器只需要三个mosfet作为开关器件。分析了多端口转换器对给定应用的适用性,并建立了一个原型转换器并进行了测试以证明理论预测。测量结果与分析结果有很好的相关性。

Multi-Port Converter with bidirectional energy flow for automotive energy net applications
A novel family of multi-port converters with bidirectional energy flow has been investigated for low-voltage high-current automotive energy-net applications. An example is given of a three-port converter designed for the 14 V/42 V automotive energy net and providing the possibility to also connect a double-layer capacitor to relieve the battery from excessive current stress and to stabilize the energy net voltages. The proposed three-port converter requires only three MOSFETS as switching devices. Analyses have been performed to investigate the suitability of the multi-port converter for the given application and a prototype converter has been built and tested to prove theoretical predictions. Measurements are in good correlations with results from the analysis.
