摘要
Boost升压电路受升压芯片内部开关管的限制,难以实现较大的功率输出.根据UC3842芯片的功能特点,结合Boost拓扑结构,提出一种利用UC3842控制芯片控制的Boost变换器的设计电路,并分析工作原理和参数设计.实验结果表明,该Boost变换器的输出功率明显提高,设计电路的外接元器件较少,运行稳定,控制灵活便捷.
This paper aims at limitation of Boost converter that it cannot achieve greater power output, and according to function and characteristic of UC3842, combined Boost configuration, brought forward a design way that uses UC3842 to control Boost converter. Here work theories and parameter are analyzed. In this way the output power of Boost converter is greatly improved, fewer outer elements are needed, stable in operation and convenient for control .
