Abstract

: Multiinput converters allow to create hybrid energy systems in electric vehicles with a reduced part count. In addition, interleaved structures help to build eﬀicient converters with several possible benefits, such as low current ripple and high power density. This paper proposes utilizing a multiphase multiinput converter (MPMIC), which concentrates the aforementioned advantages and presents a comprehensive comparison with its single-phase version, called single-phase multiinput converter (SPMIC). After analysing their steady-state characteristics, SPMIC and MPMIC are designed considering same conditions. Then, two laboratory prototypes rated at 2.5kW output power are implemented to validate the analysis. Finally, these prototypes are compared in terms of voltage-gain, input current ripple, eﬀiciency, complexity, cost, and power density. The results show that MPMIC surpasses SPMIC in eﬀiciency and in input current ripple at the expense of increments in the complexity and cost. Besides, MPMIC results in comparatively high voltage gain in low power region thanks to the discontinuous current mode operation. On the other hand, it is explored that SPMIC can reach higher power density in the event of effective cooling.

电动汽车用双向多相多输入变换器的比较研究

:多输入转换器允许在电动汽车中创建混合能源系统，减少了零件数量。此外，交错结构有助于构建具有低电流纹波和高功率密度等优点的高效变换器。本文提出了一种多相多输入变换器(MPMIC)，它集中了上述优点，并与单相变换器(SPMIC)进行了全面比较。在分析了它们的稳态特性后，在相同的条件下设计了SPMIC和MPMIC。然后，实现了两个额定2.5kW输出功率的实验室原型来验证分析。最后，这些原型在电压增益、输入电流纹波、效率、复杂性、成本和功率密度方面进行了比较。结果表明，MPMIC在效率和输入纹波方面优于SPMIC，但代价是复杂度和成本的增加。此外，由于电流模式的不连续工作，MPMIC在低功率区域具有较高的电压增益。另一方面，探讨了在有效冷却的情况下，SPMIC可以达到更高的功率密度。
