A non-isolated single-input dual-output boost DC-DC converter

A new non-isolated single-input dual-output boost DC-DC converter is introduced in this paper. The motivation of the work is that in various applications such as some multilevel converters, it is required to provide multiple dc sources that are not required to be isolated. In the proposed structure, the output ports of the converter can provide different values of power and still balance the output voltage. Even, if required, the output voltages can be set to different values. From practical point of view, the proposed topology uses minimum number of power-electronic switches (two switches for two outputs) which have common ground making their drive circuit simple and easy to implement. The state-space modelling of the proposed converter is presented, then, the model is used to design the passive elements. Moreover, the proposed converter is compared with the relevant converters. In order to verify the performance of the proposed DC-DC converter, a prototype of the converter has been implemented and the results are presented.
