High step-up single-stage boost inverter
2011 IEEE Energy Conversion Congress and Exposition, 2011This paper presents a high step-up single-stage boost inverter. The basic topology is known in the literature as a Z-source inverter (ZSI). The ZSI has the ability of buck-boost conversion. No dead time is needed in phase legs, so high reliability can be achieved.

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 ...

An interleaved high step-up switched-capacitor converter
The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014), 2014A combination of interleaving and switched-capacitor techniques is used to introduce a high step-up converter in this paper. High voltage gain without very high duty cycle and transformer can be achieved in the proposed converter. The configuration of the proposed converter not only reduces the current stress but also decreases the input current ripple,

Non-isolated high step-up interleaved boost converter
International Journal of Power Electronics, 2014The output voltage available from renewable sources like photovoltaic panels, fuel cells and battery banks are too low to be practically utilised. Therefore, the available voltage must be stepped up considerably before connecting to the load. In this paper, a novel topology, which consists of two interleaved stages and five voltage multiplier cells, is

Interleaved High Step-Up Converter With Coupled Inductors
IEEE Transactions on Power Electronics, 2019This paper proposes a new interleaved high step-up converter with coupled inductors. Interleaving configuration is employed at the input side to reduce the input current ripple and increase the power level. The series structure at the output side helps achieve a very high step-up voltage gain.
