提出了一种新的多元件谐振变换器无源集成方法。基于这种方法，可以实现三元件或更高阶元件谐振变换器的无源集成。大部分无源元件（电容、电感和Transformer）集成在一个模块中，以实现高功率密度。提出的多绕组Transformer结构集成电感和电容进行了详细的悬臂梁模型分析。总结了控制元件值的设计准则。搭建了一台1.2kW、800 kHz、400 V/48 V五元件谐振变换器样机，并进行了实验验证。功率密度可达171 W/inch 3。
This paper proposes a novel passive integration method for multi-element resonant converters. Based on this method, the passive integration for 3-element, or higher order elements resonant converters are achievable. Most of passive components (capacitors, inductors and transformer) are integrated into one module to achieve high power density. The proposed multi-winding transformer structure with integrated inductor and capacitor are analyzed with a detailed cantilever model. Design guidelines are summarized for the control of the component values. One prototype of 1.2kW, 800 kHz 400V/48V 5-element resonant converter is built and tested to verify the proposed structure. The power density can be achieved as high as 171W/inch3.
