Parameter study of boost inverter topologies for high voltage gain
Published 2019“…For generating shoot through boost voltage, A DC envelope is introduced with the carrier signals to compare with it and make boost through zero state PWM signals, which have to be added with the traditional Modulated PWM, that are usually generated through comparison of the modulating sine wave with the carrier wave. In this research, the main objective is to designs a Z-source network circuit, SL Z-source inverter and embed with traditional single-phase H-bridge and to develop control logic, that would supply SPWM switching signals to IGBT gates. …”

Effect of high velocity oxy-fuel (HVOF) coatings on fatigue behaviour of carbon steel
Published 2021“…Fatigue test was performed under the stress ratio, R = -1 in accordance with ASTM-E466 by tension-compression cyclic loading (sine wave) with a frequency of 20 Hz. The results showed that the microhardness of the coated steel decreased by 40% and the yield strength of the coated steel decreased by 9.5% due to the increment of the substrate´s grain size resulting from the high HVOF flame temperature (2750 ˚C). …”
