Abstract
This study deals with the design of a modular converter that can convert the output voltage according to the size of the load. The efficiency of the converter depends on the size of the load and is generally less efficient for lower loads. Therefore, it is more efficient to construct a small capacity modular converter than to manufacture a large capacity converter and it determines the capacity of the system through the parallel connection of the converter module according to the load size. In this paper, we will introduce a modular DC / DC converter designed to control the number of modules according to the load. A programmable resistor is placed at the output of the module for parallel connection of the module, and the voltage is regulated by adjusting the variable resistor. A system controlled in this way was found to exhibit an efficiency improvement of about 32%.
