摘要

实际市场上的中低功率电池充电功率变换器主要是基于PFC和DC/DC变换器相结合的两级概念。这些系统的效率和功率密度正在通过更高的开关频率和减少开关损耗的新半导体技术得到改善。相反，更新的晶体管占器件成本的很大一部分，并且在单一晶体管交换的情况下对总成本产生负面影响。本文介绍了一种适应现代拓扑结构，实现隔离型AC/DC变换器尺寸最小化和成本优化的方法。

Innovative Single Stage Isolated AC/DC Converter with Power Factor Correction

The actual market of low and middle power battery charging power converters is mainly based on two-stage concepts combining PFC and DC/DC converter. The efficiency and power density of those systems are being improved by newer semiconductor technology with higher switching frequency and reduced appearance of switching losses. Adversely newer transistors represent a significant share of device cost and have a negative impact on total cost in case of a sole transistor exchange. This paper describes a perspective way how to minimize the dimension and optimize cost of isolated AC/DC converters by adapting to modern topologies.
