MULTI-CHANNEL DIGITAL-ANALOG SYSTEM BASED ON CURRENT-CURRENT CONVERTERS

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2020
An approach to building a multi-channel digital-analog system is proposed, in which, unlike the known ones, a code-current converter, a controlled current generator, and also a current communication block are used. For a given accuracy, this saves on the

Frequency Response of PV Inverters Toward High Renewable Penetrated Distribution Networks

open access: yes, 2022
Substantial usage of electronic-based renewable energy resources has completely changed the dynamic behaviours and response time of power networks, which are now fundamentally different from traditional power networks dominated by Synchronous Generators (

Vibrations of cracked functionally graded beams: General solution and application – A review

open access: yesVietnam Journal of Mechanics, 2022
This paper presents a unified approach to vibration analysis of functionally graded beams with transverse open-edge cracks based on the so-called vibration shape obtained as a general solution of vibration equations in the frequency domain. The crack is
