Analysis of output voltage ripple for dual randomized PWM buck converter operating in continuous and discontinuous conduction modes
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Dual Randomized Pulse Width Modulation (DRPWM) is renowned for its better effectiveness than Simple Randomized Pulse Width Modulation (SRPWM) in reducing conducted Electro-Magnetic Interferences (EMI) in power converters. ... -
CFD modelling of a secondary settling tanks: generalization based on database relations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The modelling of a secondary settling tank area using numerical methods has been quite extensively explored and researched by numerous authors and papers. These developed models utilize different approaches, from efforts ... -
Effect of pigments on bond strength between coloured concrete and steel reinforcement
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The effect of pigments on mechanical properties of coloured concrete intended for structural applications, including the bond stress-slip behaviour to embedded steel bars, is not well understood. Series of concrete mixtures ... -
