提出了一种以高功率密度为主要目标的多千瓦级变换器的概念。高功率密度通过实现：ZVS，准zcs拓扑和集成的热电磁设计。ZVS，准zcs拓扑结构降低了IGBT开关的开关损耗，从而提高了高频变换器的效率。大功率、高功率密度变压器采用热电磁一体化设计，采用非晶铁芯、箔缠绕技术和热管。一个功能齐全的50kw DC/DC转换器（750 V/600 V）和一个虚拟转换器原型展示了转换器概念的可能性。高功率密度（高达13千瓦/升无散热器）和高效率（高达97%）是可以实现的，通过使用拟议的转换器概念
A converter concept in the multi-kilowatt class with a high power density being the main goal is presented. High power density is achieved by implementing: ZVS, quasi-ZCS topology and integrated thermal and electromagnetic design. ZVS, quasi-ZCS topology reduces switching losses of IGBT switches and hence improves converter efficiency at high frequencies. Integrated thermal and electromagnetic design is used in high-power, high power density transformer which uses amorphous cores and foil winding technology together with heat pipes. A fully functional 50 kW DC/DC converter (750 V/600 V) and a virtual converter prototype demonstrate the possibilities of the converter concept. High power density (up to 13 kW/l without heatsink) and high efficiency (up to 97%) are achievable by using the proposed converter concept
