| 摘 要： | 本文提出一种新型的Boost-Buck变换器,该变换器具有输入输出电流连续、输出电压可调范围大等优点。由于该变换器的输入电流连续,所以适合于功率因数校正电路,且其实现较为简单。该变换器的输出电压可调范围大,可以大于(或小于)输入电压,这就很好地克服了传统Boost变换器输出电压必须大于输入电压的缺点。理论分析、仿真和实验均验证了该变换器的实用性。

| Abstract: | A novel Boost-Buck converter is proposed in this paper. The converter has a continue input and output current,and wide output voltage range. For the continuous input current,the converter can be used in power factor corrector, and the realization is simple. Since the output voltage could be bigger or smaller than the input voltage, the converter can solve the limitation of the Boost converter that its output voltage must bigger than the input voltage. The proposed converter is analyzed,simulated and experimentally verified. |
