This article addresses this gap by presenting a comprehensive review of common dc-link MLCs, covering their topological evolution, features, topologies comparison, modulation techniques, control strategies, and industrial application areas. Additionally, future perspectives and recommendations are discussed to provide researchers and engineers with a better understanding of the potential applications and advantages of these converters.1.Introduction. Considering the major evolutionary stages o

What distinguishes a cable from a wire? One of the fundamental questions that still has to be explained .The cable remains to be a single conductor, whichis referred to as a wire, if there was no insulation ontwo conductors.Cable is a collection of two (or)more insulated conductors, whereas wire is a single conductor.A wire is typically a single strand or a number of strands of conductive material, such as copper or aluminium, whereas a cable is made up of two (or)more insulated wires enclosed i

Current is often measured directly using a data acquisition (DAQ) device.DAQ devices that measure voltage, on the other end, are frequently more easily accessible to the user.This method necessitates converting the current to voltage in order for the voltage DAQ device to read the signal.This can be accomplished with an electrical shunt, but it needs a system having a high input impedance. Calculations using established formulas are also required to determine the optimal shunt to use.Input Imped

Voltage instability is a serious phenomenon that can occur in a power system because of critical or stressed conditions. To prevent voltage collapse caused by such instability, accurate voltage collapse prediction is necessary for power system planning and operation. This paper proposes a novel collapse prediction index (NCPI) to assess the voltage stability conditions of the power system and the critical conditions of lines. The effectiveness and applicability of the proposed index are investi

This paper proposes a novel configuration of a dual UPQC supplied by a dual photovoltaic (PV), hereinafter referred to as 2UPQC-2PV,to improve the power quality performance of a single-phase 220 V/50 Hz distribution system. The 2UPQC-2PV configuration is proposed to anticipate the possible failure of both inverters in one of the UPQC circuits. The PV array replaces the DC-link capacitor to maintain its voltage connected to the DC-link of the UPQC constant while at the same time supplying active

This paper presented an overview of the characteristics of GFM inverters by comparison with those of traditional grid-following inverters, and the recent innovations in GFM inverter technologies were highlighted, summarizing the benefits and opportunities of GFM inverters for grid interactive operations under different scenarios.1.The functions of GFM inverters. GFM inverters are generally designed as voltage sources that regulate their voltages and frequencies in synergy with power grids thr

The design and advantages of a novel light emitting diode (LED) bandwidth extension technique, based on the adoption of negative impedance converters (NICs), are discussed in the context of visible light communication systems. The design principles of the proposed negative impedance converter are introduced, with analytical derivations of the impedance frequency behaviour and the circuit performance frequency limitations. A two-transistor circuit is designed to generate a negative capacitance ov

The increasing demand for high performance and energy efficiency in Artificial Neural Networks (ANNs) accelerators has driven a wide range of application-specific integrated circuits (ASICs). Besides, the rapid deployment of low-power IoT devices requires highly efficient computing, which as a result urges the need to explore low-power hardware implementations in different domains. This paper proposes a spatially unrolled time-domain accelerator that uses an ultra-low-power digital-to-time conve

This paper presents the open-source Python-based parameter extractor (SEKV-E) for the simplified EKV (sEKV) model, which enables the modern low-power circuit designs with the inversion coefficient design methodology. The tool extracts the essential sEKV parameters automatically from the given I - V curves using the direct extraction and the multi-stage optimization process. It also handles the overfitting issue because of non-linear least squares. Moreover, this work demonstrates t

With the increasing demand for transparent/flexible displays, healthcare sensors, and robotics, there is a need to advance the development of thin-film transistors (TFTs) manufacturing and large-scale circuits. This paper has proposed an IGZO-TFT-PDK to aid the educators and research community to explore the circuit design space of dual-gate IGZO-TFT devices. To solve the tensile force-induced current variation problem in IGZO-TFT devices, an omni-directional device and its layout template with
