升压电源常用于将低压输入转换成较高电压。不过,随着这些电源的功率需求不断增加,单个功率级可能变得缺乏吸引力。本文将介绍一种交错式升压技术,无论从分析还是从实际应用经验上来说,该技术在效率、尺寸及成本方面均优于单升压转换器(single-boost converter)。本文对250W单相电源与交错式 Boost power supplies are commonly used to convert low-voltage inputs to higher voltages. However, as the power requirements of these power sources continue to increase, a single power stage may become less attractive. This article describes an interleaved boost technique that outperforms single-boost converters in terms of efficiency, size, and cost, both from an analysis and from practical application experience. This article on the 250W single-phase power and staggered
