摘要

交错升压变换器工作在断续导通模式下具有零电流开关能力，同时保持低输入输出纹波电流，具有良好的转换效率。但是，这种变换器一直以交错运行的方式运行，在轻负荷条件下效率很低。本文提出了一种基于电流连续或断续模式检测的自动操作区域选择开关。有了这个开关，在轻负荷状态下，只有一个变流器被激活，而在满负荷状态下，两个变流器将被激活。利用LTspice软件进行的仿真结果表明，在各种负载条件下，与传统升压变换器相比，所提出的升压变换器具有更好的效率，效率范围为84.6% ~ 95.32%。

Operation Region Selector Circuit to Obtain Maximum Efficiency of 250 W Boost Converter

Interleaved boost converter gives good conversion efficiency due to its zero-current switching capability when operating in discontinuous conduction mode while keeping its input-output ripple current low. However, operating this kind of converter at interleaved operation for all the time gives poor efficiency under light-load condition. In this paper, an automatic operation region selector switch based on detection of the continuous or discontinuous current mode is proposed. With this switch, during the light-load condition, only one converter is activated, while during full-load condition both converters will be activated. The simulation results using LTspice software show that the proposed boost converter has a better efficiency compared to the conventional boost converter with efficiency range of 84.6 % to 95.32 % under various load conditions.
