Abstract

A compact, highly efficient 50-W power supply module has been developed. It has a power density of 30 W/inch/sup 3/ and an efficiency of up to 90%. Total power loss is reduced by using MOSFET synchronous rectification and choosing the optimum switching frequency. Under forced air convection, this module does not need a heat sink. It is only 8.5 mm high.<>

用于电信系统的紧凑型高效 50 瓦车载电源模块

我们开发出了一种紧凑、高效的 50 瓦电源模块。它的功率密度为 30 W/英寸/sup 3/，效率高达 90%。通过使用 MOSFET 同步整流和选择最佳开关频率，总功率损耗得以降低。在强制空气对流条件下，该模块无需散热器。高度仅为 8.5 毫米。
