摘要：
The paper focuses on a DC/DC converter that is used to adapt a varying output voltage from a solar panel to demands of an electrolyzer unit or battery charging purposes. The converter covers an input voltage span from 9 V to 24 V and has an output voltage of 12 V at a maximum current of 50 A. A modular topology of the converter is described along with a microcontroller control strategy. Finally, the efficiency increase of the synchronous interleaved buck-boost converter in various operating modes and load changes is experimentally evaluated and compared to the 2-transistor buck-boost converter.
