Variable-speed drives in any machine provide an accurate control and high-energy efficiency. More and more often machines are excited by non-sinusoidal voltages. Predicting the amount of iron losses in non-sinusoidal excitation is important. The paper aims to achieve accurate efficiency...

The Recast of the EPBD (Energy Performance of Buildings) Directive from the 2010 introduced the definition of a “nearly zero energy building”, covering its energy needs from renewable sources. In energy efficient buildings the energy needs depend strongly on the running conditions. Thus,...
