A high step up boost converter
2018 International Conference on Power, Signals, Control and Computation (EPSCICON), 2018Based on the addition of conventional boost converter, a new non-isolated step up converter is proposed. It is mainly used in high voltage application where a high conversion is required. The main feature is the possibility of modularity of the structure. The control and implementation is simple. Also the balance across the capacitor is natural.

High-efficiency, high step-up DC-DC converters
IEEE Transactions on Power Electronics, 2003Many applications call for high step-up DC-DC converters that do not require isolation. Some DC-DC converters can provide high step-up voltage gain, but with the penalty of either an extreme duty ratio or a large amount of circulating energy. DC-DC converters with coupled inductors can provide high voltage gain, but their efficiency is degraded by the ...

A New High Step-Up Interleaved LLC Converter
2021 12th Power Electronics, Drive Systems, and Technologies Conference (PEDSTC), 2021In this study, a new LLC resonant converter for high-voltage high-power applications is introduced. The introduced power converter is a two-phase interleaved full-bridge based that uses a transformer with secondary and tertiary windings to obtain higher output voltage. Zero voltage switching (ZVS) at MOSFETs turn on and zero current switching (ZCS) for

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 ...

Non-isolated high-step-up resonant DC/DC converter
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016A non-isolated high-step-up resonant DC/DC converter made up of a resonant inverter and a passive switched-capacitor (SC) rectifier, is proposed in this paper. The proposed converter is free of transformer and coupled-inductor. Thus, issues related to the leakage inductance and the large volume magnetic component caused by large turn's ratio of high ...

Nonisolated High Step-up Boost Converter Integrated With Sepic Converter
IEEE Transactions on Power Electronics, 2010For a nonisolated high step-up converter, the combination of a boost converter with a series output module is investigated in this paper. As a solution to supplement the insufficient step-up ratio and distribute a voltage stress of a classical boost converter, a sepic-integrated boost (SIB) converter, which provides an additional step-up gain with the ...
