The Model-Driven Architecture (MDA) vision of the Object Management Group offers a unique opportunity for introducing Graph Transformation (GT) technology to the software industry. The paper proposes a domainspecific refinement of MDA, and describes a practical manifestation of MDA called Model-Integrated Computing (MIC). MIC extends MDA towards domainspecific modeling languages, and it is well...

In order to investigate the grid integration of wind turbines (WT) various scales and designs, a turbine emulator (WTE) is being built in Flensburg within state-funded project GrinSH. The special feature this WTE use large gas engine instead an electric motor emulate behavior WT. develop controls innovative design upcoming test runs under safe conditions, software loop model (SILM) was applied....

This paper proposes a solar PV powered Integrated multiple output synchronous buck converter for battery operated portable applications like Electric vehicles,Mp3 players,cellular phones,Digital cameras etc.,This project deals with the operational principle, performance characteristics of a simplified dual output buck converter and solar pv powered batteries for electric vehicle power supply.Th...

The series-parallel resonant converter and its magnetic components are analysed by extended fundamental frequency techniques. The proposed model allows an easy design of the resonant circuit and the integrated transformer and the calculation of the losses of all components of the converter. The purpose of the presented analytic model is an optimisation of the converter system – minimising eithe...

This integrated single inductor dual-output boost DC/DC converter provides two independently regulated outputs with maximum efficiency at 83%. The converter operates in PWM and discontinuous mode at 500kHz using a 6.8uH inductor. Each output is time-multiplexed and regulated via current mode control. A drain-extended 0.13um technology allows backlight application up to 11V operation. The chip o...

The series-parallel resonant converter and its magnetic components are analysed by fundamental frequency techniques. The proposed method allows an easy design of the integrated transformer and the calculation of the losses of all components of the converter. Thus, an optimisation of the whole converter system – minimising either the volume and/or the losses of the converter (upper temperature i...

The DC-DC converters are widely used in photovoltaic generating systems as an interface between PV module and the load. These converters must be chosen to be able to match the maximum power point (MPP) of PV module when climatic conditions change with different resistive load values. So DC-DC converters must be used with MPPT controller in order to reduce losses in the global PV system. This ar...

Negative impedance converter circuits (NICs) are important building blocks in design and manufacturing of analog and mixed mode integrated circuits. In this paper, a catalogue of single current feedback amplifier-based negative impedance converter circuits having impedance scaling properties is proposed. Various examples are presented to illustrate the versatility of proposed NIC circuits.
