A Review on Emerging Topology of LUO Converter

By Tamboli K. B., A.A. Bhole

Abstract: AbstractLUO converters are novel series of chopper which convert fix DC voltage into variable DC voltage magnitude. Converters are popular structure that conventionally implemented with regulation of voltage and having higher (THD) Total Harmonic Distortion, lower power factor for power transmitting process. For DC application LUO Converter topology can be favored. DC-DC chopper has advantages such as better output regulation, compact size, high efficiency, and minimum cost. This paper represents …

Power-Efficient Design Strategies for Static Random Access Memory with Memory Blocks: A Review

By Biswaranjan Barik, P. V. Dileep Bhumireddi

Abstract: For many years, CMOS technology has been able to achieve high integration density and great performance by scaling down its feature size and threshold voltage. Power consumption has been a major concern in VLSI design due to the ongoing drop in aspect ratio and the related improvements in chip density and operation frequency. SRAM is a type of random-access memory in which an interruption in power causes data loss. For …

A Transformer-based Multilevel Inverter with Lesser Components

By Aravind Venugopal, Phejil K. Paul

Abstract: This paper presents a multilevel inverter topology with lesser number of components than a conventional multilevel inverter, thereby reducing the overall cost of the same. Here, a nine-level transformer-based multilevel inverter topology is proposed which uses only 8 switches while a conventional transformer-less multilevel inverter uses 16 switches for achieving the same voltage level. The structure consists of a single dc source feeding two standard H-bridges. The process of intermediate …

Study of Current Conveyors for Signal Processing Applications

By Radhika Singh, Rishikesh Pandey

Abstract: Current conveyors are basic analog building blocks used for voltage as well as current processing applications. Current conveyors are used as a voltage or current buffer in many applications. They are used for high frequency, high bandwidth, high dynamic range, better linearity, high driving capability, low voltage and low power applications. Current conveyors modify the limitations of low impedance at the output, tradeoff between speed and bandwidth and constant gain …

Simulation of Sub-synchronous Resonance (SSR), and Mitigation of SSR by Static Synchronous Series Compensator with Lead Lag Compensator

By shikha batwal, amita mahor

Abstract: This research work presents a narrative method of alleviating the SSR problem using a static synchronous series compensator (SSSC). This method is based on using the SSSC to inject unbalanced series quadrature voltages and unbalanced shunt reactive currents in transmission line just after clearing faults. When the sub-synchronous oscillations drive unsymmetrical phase currents, the developed electromagnetic torque will be lower than the condition when three-phase currents are symmetrical. The unsymmetrical …

Improvement of Indirect Vector Control Induction Motor Drive Performance under Low Speed Operation using Five-Level Inverter

By CH.V. Seshagiri Rao, P.S.R. Murthy, G Durgasukumar

Abstract: The dynamic performance of vector controlled induction motor drive is poor and peak motor torque decreases under low speed operation. This reduction in torque is due to the non-linearity of voltage to frequency (Hz) during low frequency operation. The non-linearity is caused by stator voltage drop which in turn requires a larger percentage of overall terminal voltage. To overcome these problems multilevel inverter fed induction motor drive is presented in …
