High Step-Up Converter Based on Charge Pump and Boost Converter
IEEE Transactions on Power Electronics, 2010In this paper, a novel step-up converter is presented, where the charge pump concept, combined with the traditional boost converter structure, is utilized. Although two inductors are used in such a converter, the difference in value between the two inductors affects the regulation performance of this converter slightly.

High Step-Up Converter With Coupled-Inductor
IEEE Transactions on Power Electronics, 2005In this study, a high step-up converter with a coupled-inductor is investigated. In the proposed strategy, a coupled inductor with a lower-voltage-rated switch is used for raising the voltage gain (whether the switch is turned on or turned off). Moreover, a passive regenerative snubber is utilized for absorbing the energy of stray inductance so that ...

A Novel High Step-up Converter for Photovoltaic Systems
2022 IEEE 7th Southern Power Electronics Conference (SPEC), 2022A bipolar high step-up Cuk-Sepic converters based on the 'coat circuit' is proposed, which can be used to connect single photovoltaic (PV) panel and inverters. The main advantage of the proposed converter is that it contains only one active switch as the same as the Cuk or Sepic converter, so it is easy to drive and control.
