A Buck-Boost Converter with High-voltage Conversion Gain
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.
