Non-Intrusive Load Monitoring (NILM) has gradually become a research focus in recent years to measure the power consumption households for energy conservation. Most of existing algorithms on NILM models independently when total current load appliances occurs, and usually undergoes problem signatures appliance. This paper presents distingue design classify by investigating inrush pattern allianc...

A feed forward neural network (FFNN) has been trained to discriminate between power transformer magnetizing inrush and fault currents. The training algorithm used was back-propagation, assuming initially a sigmoid transfer function for the network’s processing units (“neurons”). Once the network was trained the units’ transfer function was changed to hard limiters with thresholds equal to the b...

Transformer inrush currents are highmagnitude, harmonic-rich currents generated when transformer cores are driven into saturation during energization. These currents have undesirable effects, including potential damage or loss-of-life to the transformer, protective relay misoperation, and reduced power quality on the system. Controlled transformer switching can potentially eliminate these trans...

A step-up bridgeless single phase ac-dc power factor correction (PFC) rectifier based on Cuk topology is proposed for high voltage battery charger application. The proposed topology consists of common input stage and parallel output stages. It utilizes one control signal over the whole line cycle. In addition, the proposed converter exhibits low inrush current and low magnetic emissions as clas...

FAN7340 is a single-channel boost controller that integrates an N-channel dimming MOSFET using Fairchild’s proprietary planar DMOS technology. The IC operates as a constant-current source for driving high-current LEDs. FAN7340 uses a current-mode control with programmable slope compensation to prevent sub-harmonic oscillation and provides protections such as Open-LED Protection (OLP) and Over-V...
