| 摘 要： | 针对传统的多输入变换器(MIC)具有电路结构复杂、电压增益低或开关器件电压应力高的问题,提出了一种新型双输入Boost变换器拓扑结构.该拓扑由2个完全一致的基本Boost变换器子拓扑构成,每个基本Boost变换器的功率开关管分别并联一个功率二极管,在单输入状态时一个始终导通.另一个始终关断;在双输入状态时,2个功率二极管全部关断.分析了2种输入状态下的工作原理及各个阶段的工作模态,结果表明该变换器适合工作在双输入状态,且在此状态时可以实现2种不同性质的电源输入,具有电压增益高、开关器件电压应力低等优点.研制了一台输出功率为240 W的双输入Boost变换器原理样机,通过实验验证了理论分析的正确性.

| Abstract: | As the traditional MIC(Multi-Input Converter) has complex structure,low voltage gain and high switch voltage stress,a double-input Boost converter is proposed,which consists of two identical basic Boost converters.A power diode is added in parallel to the power switch of each Boost converter.In single-input state,one diode is always on and the other always off,while in double-input state,both are off.The operating principle and modes of both states are analyzed and the results show that the double-input Boo... |
