Abstract: This paper addresses a circuit theory regarding the negative group delay (NGD) principle. The methodology for characterizing this unfamiliar NGD function is described. The basic NGD topology ...
Abstract: In active neutral-point clamped (ANPC) converters using wide bandgap devices, high switching speeds and inevitable loop parasitics cause voltage overshoot and oscillations during commutation ...
The use of piezoelectric materials for the development of electromechanical devices for the harvesting or scavenging of ambient vibrations has been extensively studied over the last decade. The energy ...
