In applications where the high voltage gain is required, such as photovoltaic grid-connected system, fuel cell and high intensity discharge (HID) lamps for automobile, high step-up DC-DC converters have been introduced to boost the low voltage to a high bus voltage. The voltage gain of traditional Boost converter is limited considering the issues such as the system efficiency and current ripple. This paper proposes a class of hybrid switched-inductor converters for high step-up voltage gain conversion. Firstly, the topological derivation of hybrid switched-inductor converters is deduced by combining the passive and active switched-inductor unit; secondly, this paper illustrates the operation modes of the proposed asymmetrical and symmetrical converters; thirdly, the performance of the proposed converters is analyzed in detail and compared to existing converters; finally, a prototype is established in the lab, and the experimental results are given to verify the correctness of the analysis.Index Terms-Switched-inductor, high step-up, DC/DC converter.

High boost converters, because of its ability of having high gain level, have become important in applications for energy generation known as renewable sources. High efficiency, few components and low voltage and current stress on switches are desired features in these kinds of converters. Double tapped boost converter with just a single switch is proposed in this study for high gain; two pairs of coupled magnetically coils are charged in parallel and discharged in series with the source, this let us to obtain not only a higher gain with very few components but also an acceptable efficiency. Not only analysis for the topology is shown, but also simulation and experimental results are presented in order to illustrate the system behaviour for an output power of 200 W. The system efficiency is closer to 90% at hard switching.

Affected by the equivalent series resistance (ESR) of the devices in the circuit, the voltage-conversion ratio of traditional boost converter is limited. Various topologies have been developed to provide a high step-up voltage gain. An inherent high voltage gain can be achieved in a dual-switch converter with the advantages of low voltage and current stress on the switches. However, this converter has a strict requirement of the parameters' consistency. This paper discusses the steady-state operation principle of the converter in detail under the condition that the parameters are inconsistent and then illustrates the solutions to balance the voltage on the switches and suppress the resonance with passive lossless clamping. Finally, a prototype has been established in the laboratory, and simulation and experimental results have been given to verify the analysis and the effectiveness of clamping method.Index Terms-High step-up voltage gain, parameters are inconsistent, passive lossless clamping, resonance.
