Development of low-profile DC/DC converter using switched-capacitor circuits and coreless PCB gate drive

, 1999
This paper presents the design and analysis of a low-profile multi-stage current-controlled switched-capacitor (SC) step-down dc/dc converter. The converter not only exhibits all advantages of classical SC converters, but also features good regulation ...

Kaleidoscopic Electromagnetic Wave Manipulation via a Universal Reconfigurable Metasurface Platform

Electron, EarlyView.
A multidimensional reconfigurable metasurface enables independent control of the amplitude, phase, polarization, and spectral responses of reflected electromagnetic (EM) waves. Integrating spatial, polarization, and spectral manipulation within a single platform, it provides a versatile solution for intelligent EM systems, next‐generation wireless ...

Optimal Lithium‐Ion Battery—Supercapacitor Energy Storage System Capacity for Off‐Grid Intermittent Renewable Energy Mini‐Grids

Energy Science &Engineering, EarlyView.
Deployment of an aging‐based controller during designing of optimal lithium‐ion battery—supercapacitor (LB‐Sc) hybrid energy storage system (HESS) capacity, in off‐grid IREMGs, improves performance of the LB and reduces its aging rate. Also, annualised cost of the LB‐Sc HESS improves by 33.15% in relation to optimal LB SESS.

Ambiguity‐Aware Receding‐Horizon Optimization of Wind‐Hybrid Energy Storage Systems Using Type‐3 Fuzzy Modeling for Multimarket Participation

Energy Science &Engineering, EarlyView.
A Type‐3 fuzzy ambiguity encoder converts rolling wind, price, reserve‐activation, and confidence features into central estimates and nested uncertainty bounds. These parameters are updated within a receding‐horizon MILP/MIQP that coordinates wind, battery, and supercapacitor capacity across day‐ahead and ancillary‐service markets.

Comments and Corrections Comments on “Design and Analysis of Switched-Capacitor- Based Step-Up Resonant Converters”

, 2008
—With reference to a recently published paper, the realization of line and load regulation in switched-capacitor-based converters is discussed. We point out that achieving zero-current switching at the expense of losing line and load regulation is not ...

A Comprehensive Review of Fault‐Current Limiter Technologies for Smart and Resilient Power Systems

Energy Science &Engineering, EarlyView.
This review compares superconducting, solid‐state, and hybrid fault‐current limiters (FCLs) for modern alternating current, direct current, and hybrid grids. It shows that optimal FCL selection depends on fault characteristics, network configuration, voltage level, protection coordination, and resilience requirements rather than on a universally ...
