A new hybrid high voltage gain dc–dc converter is created by merging the standard boost converter with a coupled inductor and different switched-capacitor techniques, with a single switch and no requirement of higher duty cycle values.Abstract:
High step-up converters are required for distributed photovoltaic generation systems, due to the low voltage of the photovoltaic source. In this paper, a new hybrid high voltage gain dc–dc converter is created by merging the standard boost converter with a coupled inductor and different switched-capacitor techniques. With a single switch and no requirement of higher duty cycle values, the proposed converter achieves a high voltage gain and high efficiency, in addition to lowered voltage and current stresses of the components. A 200-W prototype was implemented experimentally to evaluate the converter, which reached a maximum efficiency of 97.6%.read more

Analysis and design of bipolar Dickson DC-DC converter
TL;DR: In this paper, a novel converter based on the Dickson voltage multiplier for high voltage applications is presented. But the converter is not suitable for the high-voltage applications, as the voltage ripples are too large to be absorbed by the converter.
