Stability analysis of grid-connected PV generation with an adapted reactive power control strategy

open access: yesThe Journal of Engineering, 2019
The static VAR compensator is widely applied in large-scale grid-connected photovoltaic (PV) generation to participate in voltage regulation of power system, which ignores the reactive power regulation capability of PV inverter.

Invertor system stability analysis

open access: yesIFAC Proceedings Volumes, 1974
Summary A single phase bridge inverter system is analyzed. It is assumed that the inverter is used as a closed loop voltage regulated. source of ac power. The inverter output waveform is pulse width modulated to control the output voltage which is supplied to a general linear filter.

A rotating arc plasma invertor [PDF]

open access: yes, 1987
A device is described for the inversion of direct current to alternating current. The main feature is the use of a rotating plasma arc in crossed electric and magnetic fields as a switch. This device may provide an economic alternative to other inversion methods in some circumstances.

The impact of CMOS scaling projected on a 6b full-Nyquist non-calibrated flash ADC [PDF]

open access: yes, 2009
A 6-bit 1.2 Gs/s non-calibrated flash ADC in a standard 45nm CMOS process, that achieves 0.45pJ/conv-step at full Nyquist bandwidth, is presented. Power efficient operation is achieved by a full optimization of amplifier blocks, and by innovations in the

Coordination control strategy for LLCL-filter based grid-tied inverter with indirect sliding mode power control and virtual impedance

open access: yesThe Journal of Engineering, 2019
The LLCL filter is widely used in grid-tied inverter systems due to its small size, low cost and good attenuation for high-frequency harmonics. However, the LLCL filter resonance phenomenon and the wide range of impedance may compromise the system ...

Hierarchical control of parallel voltage source inverters in AC microgrids

open access: yesThe Journal of Engineering, 2018
Here, a distributed hierarchical control strategy is proposed for the parallel operating of voltage source inverters (VSIs) in AC microgrids (MGs). For the output voltage control of a VSI, conventional double-loop proportional-integral (PI) control ...

Kinematic Foot Types in Youth with Equinovarus Secondary to Hemiplegia [PDF]

open access: yes, 2015
Background Elevated kinematic variability of the foot and ankle segments exists during gait among individuals with equinovarus secondary to hemiplegic cerebral palsy (CP). Clinicians have previously addressed such variability by developing classification

Serialized Asynchronous Links for NoC

open access: yes, 2008
This paper proposes an asynchronous serialized link for NoC that can achieve the same levels of performance in terms of flits per second as a synchronous link but with a reduced number of wires in the point to point switch links and reduced power ...
