MODELLING AND SIMULATION OF SOFT-SWITCHING DC/DC CONVERTER WITH HIGH VOLTAGE GAIN



INTRODUCTION

Recently, the demand for dc/dc converters with high
voltage gain has increased. The energy shortage and
atmosphere pollution have led to more researches on the
renewable and green energy sources such as the solar
arrays and the fuel cells. Moreover, the power systems
based on battery sources and super capacitors have been
increased. Unfortunately, the output voltages of these

This paper presents the work that is beingdone as a part of the ByFault project (Brite/Euramprojet finaced by the European Community):manufacturing, modelling and simulation of aSuperconducting Hybrid Fault Current Limiter(SHFCL). The SHFCL is based on a variableimpedance transformer: primary winding is in serieswith the protected line and several secondaries areshort-circuited by superconducting elements. Thistopology has been modelled using 2-D and 3-D finiteelements, and some useful formulation to simulate thebehaviour ....etc

Simple Non-Linear Magnetic Analysis for Permanent-MagnetMotors



The need


In the process of designing a new motor/generator;
Method of Finite Element Analysis is used

The disadvantage - Computing time

Alternate option – Nonlinear Magnetic Analysis on an equivalent magnetic circuit of the whole machine

Because of Magnetic Saturation in Stator teeth, the analysis becomes Nonlinear.



The procedure

Abstract
The proper design and simulation of modern electronic microsystems oriented towards environment monitoring requires accurate models of various ambient sensors. In particular, this paper presents a comprehensive model of an ion sensitive field effect transistor (ISFET). The model can be employed straightforwardly for simulations at device, circuit or system level. First, the model was validated with electrical measurements a ....etc

Abstract
This paper introduces a sensorless nonlinear control
scheme for controlling the speed of a permanent magnet
synchronous motor (PMSM) driving an unknown load torque.
The states of the motor and disturbance torque are estimated via
an extended nonlinear observer avoiding the use of mechanical
sensors. The control strategy is an exact feedback linearization
law, with trajectory tracking evaluated on estimated values
of the PMSM states and the disturbance torque. The system
performance is evaluated by simulations.

Optimal Designs and Comparison of the Doubly
Salient Permanent Magnet Machine and
Flux-reversal Machine in Low-speed Applications

Abstract
The subject of this is to optimize the design and to compare
The performances of a low-speed doubly salient permanent magnet machine with
Those of a low-speed flux-reversal machine devoted to direct drive applications. The
Optimization, focused on the maximization of the machines mass-to-torque ratio,

ABSTRACT
Permanent magnet synchronous motor (PMSM) has been widely used in high performance drive applications for its advantages such as compactness, high efficiency, reliability and suitability to environment. Due to its high power density and smaller size, PMSM has evolved as the preferred solution for speed and position control drives on machine tools and robots. A Permanent Magnet Synchronous Motor (PMSM) is a motor that uses permanent magnets to produce the air g ....etc
