This article proposes new transformer-less step-up/down and step-up DC–DC topologies providing numerous merits such as less voltage stress on capacitors, lower duty-cycle, higher conversion ratio compared to other converters. The proposed converters are extendible by benefiting from several switched-capacitors, making it possible transfer more power the converter. structures suitable for modern...

A new thyristor is proposed and realized in the foundry’s 0.18-μm CMOS process for electrostatic discharge (ESD) protection. Without extra mask layers or process steps, the new ultra-low-voltage-trigger thyristor (ULVT thyristor) has a trigger voltage as low as 6.7 V and an ESD robustness exceeding 50 mA/μm, which enables effective ESD protection. Compared with the traditional medium-voltage-tr...

The problem regarding the optimal placement and sizing of different FACTS (flexible alternating current transmission systems) in electrical distribution networks is addressed this research by applying a master–slave optimization approach. analyzed correspond to unified power flow controller (UPFC), thyristor-controlled shunt compensator (TCSC, also known as thyristor switched capacitor, or TSC)...

To meet with the ever-enhancing load demands, new transmission lines should be bolted-on in the existing power system but the economic and environmental concerns are major constraints to this addition. Hence utilities have to rely on the existent power system infrastructure with some modifications. To enhance controllability and boost power transfer potential of the existing power system the us...

The presented work deals with analysis of non-ideal effect of pipelined analog-to-digital converter (ADC) such as random capacitor mismatch, comparator offset and finite op-amp gain. These factors arise during a conversion in the pipelined ADC when using CMOS technology and switched-capacitors (SC) technique. The pipelined ADC was simulated in MATLAB-Simulink simulation environment. Key-Words: ...

The paper discusses the synthesis of switched-current filters from continuous-time prototypes by the simulation of components, particularly capacitors and transconductors in OTA-C filters. The obtained structures implement discretetime versions of the nodal equations of the prototype circuit using Euler or bilinear transformations over the circuit elements. All the proposed structures work with...

In the present simulation work, an attempt is made to study the switching dynamics of an optically controlled 4HSiC thyristor power semiconductor device with the use of GaAs optically triggered power transistor. The half-cell thyristor has the forward breakdown of 200 V and reverse breakdown of more than 1000 V. The optically controlled thyristor has a rise time of 0.14 μs and fall time of 0.06...

This paper proposes a pulsed power generator which consists of two types of switched-capacitor booster modules. A doubling mode module employed to elevate the input voltage to a specified level and, constant mode module is used to increase the elevated voltage into the finally intended bipolar output voltage. Also, the proposed modular structure does not utilize any switches across the load. Ot...
