Interleaved, Switched Inductor and High-Gain Wide Bandgap Based Boost Converter Proposal
Energies, 2021 Many applications (electric vehicles, renewable energies, low-voltage DC grids) require simple, high-power density and low-current ripple-boost converters. Traditional step-up converters are limited when large transformation ratios are involved.

Design of isolated IGBT driving and control circuits for an interleaved boost converter
Engineering and Applied Science Research, 2021 An IGBT/MOSFET driver circuit works at a low voltage, between 5-15 V of its gate voltage to drive power converter switching devices that work at higher voltages.

Boosting algal lipids: Diurnal shifts in temperature exceed the effects of nitrogen limitation
Engineering Reports, 2019 Algal lipids have been observed to increase during autumn conditions (low light, low mean temperature, and diurnal shift in temperature), in large‐scale outdoor photobioreactors.

Disturbed transatmospheric motion of the first stage of an aerospace system
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2020 The paper deals with disturbed transatmospheric motion of the first stage of an aerospace system. Deviations of atmospheric density and deviations of aerodynamic force coefficients from reference values are taken as disturbances.

Topology of a Three-Port Converter for High-Altitude Platforms
IEEE Access, 2022 Three-port converter (TPC) with non-regulated bus cannot meet the voltage stability demands of high-altitude platforms (HAPs) during daytime operations. In contrast, full-regulated bus TPC is complex in topology and inferior in power density, although it
