摘要

电信设备中压低电源电压(3.3 V, 2.7 V…)的趋势使得DC/DC转换系统尽可能靠近负载，从而最大限度地减少由于大电流造成的损失。在这些供电系统中，尺寸是一个关键特征，无源元件通常是体积最大的元件。本文提出了一种10瓦DC/DC变换器，其中无源元件采用混合技术集成，从而可以获得6.25 W/cm/sup /的高功率密度。

High power density DC/DC converter using thick-film hybrid technology

The tendency to push down supply voltages (3.3 V, 2.7 V...) in telecommunication equipment makes DC/DC conversion systems be placed as close as possible to the load, thus minimizing losses due to high currents. Size is a critical feature in these supply systems, with passive components usually being the bulkiest elements. A 10 watt DC/DC converter is presented in this paper where passive components have been integrated using hybrid technology, thus allowing to obtain high power density of 6.25 W/cm/sup 3/.
