Dual Output and High Voltage Gain DC-DC Converter for PV and Fuel Cell Generators Connected to DC Bipolar Microgrids

This paper introduces a new topology for DC-DC converter with bipolar output and high voltage gain. The was designed the aim to use only one active power switch. Besides multiport gain this has another important feature, namely, it continuous input current. Due self-balancing outputs, proposed is suitable DC microgrids. Indeed, balancing capability can achieve two symmetrical poles of Furthermore, possible create midpoint in that be directly connected ground supply, avoiding common-mode leakage currents critical applications such as transformerless grid-connect PV systems. operating principle will supported by mathematical analysis. To validate verify characteristics presented topology, several experimental results are shown.
