...Wojciech Pietrowski; Wojciech Ludowicz; Rafal Marek Wojciechowski Purpose The specific modulation methods are used to control different kind of single-phase, as well as three-phase, inverters to ensure flexibility and high quality of the output waveform. This paper aims to present a combination...

... (reference) signal. Also, pulse modulation components in output current of current source should be minimized. Design/methodology/approach The power electronics controlled current source utilizes both, the concept of the inductor with variable (controlled) inductance located at the output of an inverter...
