摘要

本文提出了一种具有宽电压调节范围的隔离式降压升压dc-dc变换器。该变换器具有零电压开关操作、宽输入电压调节范围等显著特点。当电压在10到60伏之间变化，输出需要恒定的直流电压时，这种拓扑结构可用于包括光伏微转换器在内的几种应用。给出了Buck、Buck-Boost和Boost能力以及各开关状态的方程。稳态分析用于计算每个模式的电压增益。最后，利用PowerSim软件进行了仿真，验证了理论评价。

A Novel Isolated Buck-Boost dc-dc Converter with Wide Range of Voltage Regulations

This paper proposed a novel isolated buck-boost dc-dc converter with wide range of voltage regulations. The proposed converter has significant features such as zero voltage switching operation, as well wide input voltage regulation range. This topology can be used in several application including Photovoltaic microconverter, when the voltage varies between 10 to 60 volts, and the output needs to be a constant dc voltage. The Buck, Buck-Boost, as well as Boost capabilities of proposed converter beside their switching states and equations of each switching states are presented. The steady state analysis is used to calculate the voltage gain for each mode. Finally, the simulation using PowerSim software is verifying the theoretical evaluation.
