High gain DC-DC converter for PV applications
2016 IEEE 59th International Midwest Symposium on Circuits and Systems (MWSCAS), 2016In this paper a new single-switch non-isolated, DC-DC converter, with high voltage transfer gain and reduced semiconductor voltage stress is proposed. The high gain converter is designed by integrating a boost with quadratic boost converters. The high voltage gain capability at moderate duty-cycle and low switch voltage stress enable the use of a lower

A High Voltage Gain Multi-Input Converter
2018 2nd International Symposium on Multidisciplinary Studies and Innovative Technologies (ISMSIT), 2018This paper proposes a non-isolated unidirectional high step-up multi-input converter based on switched capacitor cells. The proposed structure specifically useful for hybrid power systems when energy sources with low output voltages, e.g., a photovoltaic system or a fuel cell, need to be connected to a dc bus with high voltage. Moreover, it is possible

Interleaved-Boost Converter With High Voltage Gain
IEEE Transactions on Power Electronics, 2010This paper presents an interleaved-boost converter, magnetically coupled to a voltage-doubler circuit, which provides a voltage gain far higher than that of the conventional boost topology. Besides, this converter has low-voltage stress across the switches, natural-voltage balancing between output capacitors, low-input current ripple, and magnetic ...

Research on High Gain Isolated DC Converter with Boost Link
2021 International Conference on Electronics, Information, and Communication (ICEIC), 2021Resonant DC/DC converters represented by LLC are widely used in various power supply systems. But if the PFM control method is adopted when the input voltage or load range is wide, a larger frequency adjustment range will inevitably reduce the converter efficiency.

Protein-to-DNA Converter with High Signal Gain
ACS NanoDNA isothermal amplification techniques have been applied extensively for evaluating nucleic acid inputs but cannot be implemented directly on other types of biomolecules. In this work, we designed a proximity activation mechanism that converts protein input into DNA barcodes for the DNA exponential amplification reaction, which we termed PEAR. Several

High gain hybrid DC-DC converter
2014 IEEE 2nd International Conference on Electrical Energy Systems (ICEES), 2014The output voltage from renewable energy sources like photovoltaic cell or array will be at low level. This must be stepped up by an order of around 20 for practical applications or grid connection. Series connection of arrays is not a viable solution.
