摘要
开关式电源变换器的小型化主要是通过高频化和高密度化来实现的 .而高频化带来的一个严重问题是开关损耗的增大 .本文提出的具有最小开关损耗的 DC-DC升压变换器就是对解决这一矛盾的探讨 。
Small size of switch mode converter is achieved by increasing frequency and density. But increasing the frequency will bring the increment of switching losses. It is a serious problem. The problem will be solved by DC DC boost converter with switching lossless good result is got by experiment.
