A 300-800MHz Tunable Filter and Linearized LNA applied in a Low-Noise Harmonic-Rejection RF-Sampling Receiver [PDF]

open access: yes, 2010
A multiband flexible RF-sampling receiver aimed at software-defined radio is presented. The wideband RF sampling function is enabled by a recently proposed discrete-time mixing downconverter. This work exploits a voltage-sensing LNA preceded by a tunable

Electromagnetic Compatibility of Impedance Source Inverters

open access: yesElektronika ir Elektrotechnika, 2017
In the last decade, many new structures of Impedance Source Networks have been presented and applied to a variety of powering systems. Electromagnetic Compatibility (EMC) testing is a required procedure, when introducing a new product to the market, in order to confirm that a particular device meets the required standards. The novelty presented in this

An adaptive virtual impedance fault current limiter for optimal protection coordination of islanded microgrids

open access: yesIET Renewable Power Generation, 2022
Fault currents of inverter‐interfaced distributed generators (IIDGs) depend on inverter controllers. Thus, IIDGs fault currents are different than those of synchronous‐based DGs, both from the magnitude and waveshape perspectives.
