本文提出了一种设计汽车转换器的方法，其主要目标是高效率和高功率密度。通过展示两个案例研究设计和转换器原型的测量来演示该方法。高效率和高功率密度的目标是通过优化转换器设计实现的，包括软开关 SAZZ 拓扑、并联 MOSFET、集成电感器、交错转换器模块、先进的热管理和优化的空间设计。该项目的最初目标是达到尽可能高的效率并超过 10 kW/L 的功率密度。大幅超出了功率密度目标，即使对于风冷系统也达到了 17.7 kW/L 的功率密度。工作频率为 200 kHz 的单个转换器模块的测量效率高达 95.4%，完整的交错转换器原型仍有望获得更高的效率。
The paper presents an approach to designing automotive converters with main objectives being high efficiency and high power density. The approach is demonstrated by presenting two case study designs and measurements on converter prototypes. The goals of high efficiency and high power density are reached by an optimal converter design including soft switched SAZZ topology, paralleled mosfets, integrated inductors, interleaved converter modules, advanced thermal management and optimized spatial design. The initial goals of the project were to reach as high efficiency as possible and to exceed power density of 10 kW/litre. The power density goal was exceeded by a large margin reaching the power density of 17.7 kW/litre even for air-cooled system. The measured efficiency of a single converter module operating at 200 kHz is as high as 95.4% and a larger efficiency is still expected from the complete interleaved converter prototype.
