Research Focus: How does a new high gain dc-dc converter perform on a solar PV module?

A new Research paper accepted by the Journal presents a new prototype – a high-efficiency, high voltage gain DC-DC converter, which could be used with photovoltaic modules to increase output voltage in standalone or grid connected systems. In the study, a single switched high voltage gain DC-DC converter with a voltage gain of 10 is analysed, demonstrating low switching and conduction losses.
