Quaternary Logic Lookup Table in Standard CMOS

Interconnections are increasingly the dominant contributor to delay, area and energy consumption in CMOS digital circuits. Multiple-valued logic can decrease the average power required for level transitions and reduces the number of required interconnections, hence also reducing the impact of interconnections on overall energy consumption. In this paper, we propose a quaternary lookup table (LUT) [...]

An AC-DC Single-Stage Full-Bridge Converter With Improved Output Characteristics

A new auxiliary circuit for an ac-dc single-stage power-factor-corrected (SSPFC) full-bridge-type converter is proposed in this paper. The new auxiliary circuit is simple, handles low power, and is active only when the converter is operating under light load conditions. In this paper, the operation of an SSPFC converter is briefly reviewed and the main principle [...]

Household Electricity Demand Forecast Based on Context Information and User Daily Schedule Analysis From Meter Data

The very short-term load forecasting (VSTLF) problem is of particular interest for use in smart grid and automated demand response applications. An effective solution for VSTLF can facilitate real-time electricity deployment and improve its quality. In this paper, a novel approach to model the very short-term load of individual households based on context information and [...]

Model-Predictive Direct Power Control With Vector Preselection Technique for Highly Efficient Active Rectifiers

This paper proposes a novel method to reduce switching losses on the basis of a model-predictive direct power control (MPDPC) method for ac-dc active rectifiers. The main idea is to preselect voltage vectors to decrease switching losses at the next sampling period, and then select one optimum voltage vector among only the preselected voltage vectors [...]

Predictive Control of Power Converters: Designs With Guaranteed Performance

In this work, a cost function design based on Lyapunov stability concepts for finite control set model predictive control is proposed. This predictive controller design allows one to characterize the performance of the controlled converter, while providing sufficient conditions for local stability for a class of power converters. Simulation and experimental results on a buck [...]

Active Harmonic Reduction for 12-Pulse Diode Bridge Rectifier at DC Side With Two-Stage Auxiliary Circuit

A 12-pulse diode bridge rectifier is often used in high-power rectification. However, the total harmonic distortion (THD) of input line current in 12-pulse rectifier does not meet the IEEE-519 standard. In order to reduce the harmonics to an acceptable level, we use a two-stage auxiliary circuit at dc side of the 12-pulse rectifier to eliminate [...]

FPGA Implementation of Software Defined Radio-Based Flight Termination System

This paper proposes a field-programmable gate array (FPGA)-based software defined radio (SDR) implemented flight termination system (FTS). This is purely a new kind of implementation of digital FTS in SDR platform. The applied design procedure replaces a multiple platform-based system with a single platform. It also guarantees reconfigurable, interoperable, portable, and handy FTS, and maintains [...]

A Mechanism to Prevent Stuff Bits in CAN for Achieving Jitterless Communication

The bit stuffing mechanism adopted in controller area networks leads to unwanted jitter on frame reception times, which worsens timing accuracy, even if countermeasures are adopted to avoid contentions on the bus. Several solutions have been proposed so far for dealing with stuff bits in the payload of messages, but they are not effective for [...]

New Techniques and Tools for Application-Dependent Testing of FPGA-Based Components

Field programmable gate array (FPGA) devices are increasingly being deployed in industrial environments, making reconfigurable hardware testing and reliability an active area of investigation. While FPGA devices can be tested exhaustively, the so-called application-dependent test (ADT) has emerged as an effective approach ensuring reduced testing efforts and improving the manufacturing yield since it can selectively [...]

Detection of Integrity Attacks in Cyber-Physical Critical Infrastructures Using Ensemble Modeling

Energy savings optimization becomes one of the major concerns in the wireless sensor network (WSN) routing protocol design, due to the fact that most sensor nodes are equipped with the limited nonrechargeable battery power. In this paper, we focus on minimizing energy consumption and maximizing network lifetime for data relay in one-dimensional (1-D) queue network. [...]
