摘　　要：传统Buck-Boost变换器电压增益范围较窄,且开关应力较大,对此提出了一种具有高电压转换增益的Buck-Boost变换器,对其拓扑结构和工作原理进行了详细描述,理论推导了变换器的电压增益公式和开关管的电压应力,并与其他Buck-Boost变换器进行了对比分析。在搭建的实验样机上进行的验证表明所提出的Buck-Boost变换器具有高电压转换增益。The conventional Buck-Boost converters usually have narrow voltage gain band widths and high blocking voltage stresses.In view of this the present work made a preliminary attempt to propose a Buck-Boost converter with high-voltage conversion gain.It designed the converter′s topology and working principle,theoretically derived the voltage gain formula of the converter and the blocking voltage stress of the switching tube,and compared it with other Buck-Boost converters.The proposed design exhibited high-voltage conversion gain in the experimental verification carried out using a self-built prototype.
