Novel high-efficiency step-up converter
IEE Proceedings - Electric Power Applications, 2004As a result of the equivalent series resistor of the boost inductor, conventional boost converters are not able to provide high voltage gain. A high-efficiency high step-up converter is proposed, with low voltage stress on power switch, power diodes and output capacitors.

Multiphase Interleaved High Step-Up Converters
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019This paper proposes a family of multiphase interleaved high step-up converters. The multiphase interleaving structure at the input side reduces the input current ripple and increases the power level. The diode-capacitor voltage multiplier stages guarantee a high step-up voltage gain.

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 ...
