摘要
在常规升压斩波电路的基础上,采用高频软开关技术和引入电流反馈的方式,提出了一种改进型的升压斩波电路.该电路不但具有升压、降压功能,还可以使输入电流谐波明显减少,且控制方法简单.
A modified boost chopping circuit was presented in this paper. Based on the routine chop-wave circuit, the way of high-frequency soft switch and current feedback was used. The circuit can not only drop the voltage and lift the voltage, but also make the harmonic wave decreased greatly. At the same time, its control method was simple.
