This paper represents an effective method for optimal placement of DG and capacitor in distribution system. The main objective is to reduce the power losses in the system by placing capacitor and DG of optimal size and at optimal location. Distribution system connects the high voltage transmission system and low voltage side, hence it is necessary to keep the system at minimum losses for making...

This article presents a hybrid microgrid configuration with flying capacitor dual-output (FCDO) converter. The output ports of the FCDO converter can directly interface ac sources/loads operating at different amplitudes and frequencies without additional ac/dc/ac units. Compared to conventional configuration, operates multilevel voltages, reduced power conversion stages, less switch count, fewe...

The paper deals with a new 12-bit low power switched-capacitor (SC) ADC for portable applications, such PDA, notebook etc. The paper describes design of ADC and its behavioural modelling regarding low power consumption. The Op-Amp sharing technique and capacitor scaling approach are utilized to obtain it. The basic block topology design is outlined too. The cancellation techniques to avoid the ...

A 2 DOF resonant thorax structure has been designed and fabricated for the MFI project. Miniature piezoelectric PZN-PT unimorph actuators were fabricated and used to drive a four-bar transmission mechanism. The current thorax design utilizes two actuated four-bars and a spherical joint to drive a rigid wing. Rotationally compliant flexure joints have been tested with lifetimes over 10 cycles. W...

Ballast flying problems obsess the ballasted high speed railway, its microscopic mechanics is less of discovered. In the paper, the railway ballast particle force equilibrium is analyzed through basic mechanics and mathematic formula, and a model is set up to discover the factors and influence. The microscopic ballast flying model is used for ballast bed geometry and ballast shape optimization,...

Biomimetic Sensor Modeling and Simulations for Flight Control of a Micromechanical Flying Insect

A switchable operational amplifier (op-amp) that uses a switched capacitor integrator has an advantage such as low power consumption and wide gain-bandwidth product. The power reduction is achieve by apply switching samples at the input and output capacitors. These capacitors can be otherwise would contribute in increase in power consumption. During the first phase of the sample the opamp compl...

Properly sized capacitor banks are connected across induction motors for several reasons including power factor correction, reducing distortions, increasing capacity, etc. Total harmonic distortion (THD) and power factor (PF) are used in such cases to quantify the improvements obtained through connection of the external capacitor banks. On the other hand, one of the methods for assessing the mo...

An alternative method for characterizing capacitor matching is presented. The basic idea of this method is to sense the mismatch among the capacitors by amplifying the error voltage using an iterative switched-capacitor scheme. Through simulation, this method has shown attractive property for sensing capacitor mismatches down to 1% and smaller.
