Self tunning filter for three levels four legs shunt active power filter with fuzzy logic controller
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)The low harmonic distortion and reduced switching losses are the advantages of using the multilevel inverter. For this purpose, the three-level inverter is used in this paper as a three-phase four-leg shunt active power ...
The impact of the air temperature on measuring the zenith angle during the year in the ground layer of the atmosphere for the needs of engineering surveying
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)This paper presents the results of over a year-long experiment dealing with a temperature measurement to calculate the theoretical effect of the atmosphere on the measured zenith angle in engineering surveying. The ...
