A DC-DC Buck-Boost Converter with High Voltage Gain, Bipolar Output and Continuous Input Current

DC-DC converters based on the Buck-Boost characteristic is highly indicated for many applications, such as, for example photovoltaic PV generators. Another important characteristic for this kind of application is the continuous input current. In this way, in this paper it is proposed a new converter with these kinds of characteristics. Besides that, this converter is also characterized by a very wide static voltage ratio. Another characteristic of this proposal is that is characterized by two outputs which can be very useful, for example, in bipolar DC microgrids. The two switches of the converter supports a blocking voltage that is lower than the converter voltage. The behavior and particularities of these converters will be tested by computer simulations and also by experimental prototypes.
