Two-inductor Boost Converter Start-up And Steady-state Operation

open access: yesEletrônica de Potência, 2010
In this work, an isolated DC/DC two-inductor boost converter is proposed. The topology is able to start up and operate in steady-state at any output level within 0V to 400V.

Effects of propeller load fluctuations on performance and emission of a lean-burn natural gas engine at part-load conditions

open access: yesPropulsion and Power Research, 2022
Providing stable combustion of lean-burn natural gas engines was always a big challenge, particularly during a low load operation. In transient sea conditions, there is an additional concern due to irregular time-varying loads.
