Abstract

This paper introduces a new topology of the high gain non-isolated DC-DC boost converter with central point on its output. The proposed converter is derived from the quadratic single switch boost converter and the three level boost converter. The static gain of this converter is bigger than the one from the conventional boost converter and the maximum voltage on both switches is half of the output voltage. Qualitative and quantitative analysis of the operation stages, the main waveforms and the experimental results of a 520 W prototype are presented. The converter is aimed for modular photovoltaic application.
