Inverter-based resources (IBRs) possess dynamics that are significantly different from those
of synchronous-generator-based sources and as IBR penetrations grow the dynamics of …

The large-scale integration of power electronic based systems poses new challenges to the
stability and power quality of modern power grids. The wide timescale and frequency …

Paralleled inverters with asynchronous carriers are increasingly emerging into renewable
power plants and other power-electronic-based power systems. The sideband harmonics …

Real-time frequency agility is one of the key limitations of current all-digital transmitters
(ADTs). In this paper, to address this problem, an ADT based on direct-RF generation is …

Electrical railway harmonic instability issues are common in the high-frequency range. The
effective frequency of the traditional converter's small-signal averaging model is below 1/2 …

We present the uplink and downlink of a time-division duplex distributed multiple-input
multiple-output (D-MIMO) testbed, based on a 1-bit radio-over-fiber architecture, which is low …

Dual active bridge (DAB) is a topology that is receiving more and more attention as a
potential solution to interface dc grids of different voltage levels. From a system level, the …

Dead-time is commonly designed to avoid shoot-through phenomenon within each arm in
voltage source converter. The presence of dead-time tends to cause a power quality issue …

Modern grids are facing a massive integration of power electronics devices, usually
associated to instability issues. In order to assess the likelihood and severity of harmonic …

Recent studies have shown that harmonic instability may occur at frequencies above the
Nyquist frequency. To study this issue, the sidebands originating from modulation must be …
