 Abstract 
High power converters have found their way into many industries. Variety of industries processes have increased their requirements in power level, economy of scale, efficiency, new control method, new topologies and using new technologies (like new semiconductors). The incentive to move to higher frequencies is not only given by the reduced sizes of the passive components, magnetic core losses, but also the application demands. It is thus clear that much can be gained from moving to a design that enables operation at very high frequency. Hence in the recent years, high frequency high power converters have been one of the most active areas in research. In this PhD research project high power converters have been considered, regarding to their power level, as two categories of high instantaneous and high average power converters. High frequency high instantaneous power converters mostly known as pulsed power supplies are studied as the main aspect of this research, and high frequency high average power converters are investigated with the specific intention on high power piezoelectric transducer applications as the second aspect.

India celebrates putting satellite into orbit around Mars

India triumphed in its first interplanetary mission, placing a satellite into orbit around Mars on Wednesday morning and catapulting the country into an elite club of deep-space explorers Scientists broke into wild cheers as the Mars Orbiter Mission, affectionately nicknamed MOM, manoeuvred into its designated place around the red planet in an operation described as "flawless". The success marks a milestone for India's space program in demonstrating that it can conduct complex missions and act as a global launch pad for commercial, navigational and research satellites. India was particularly proud that MOM was developed with homegrown technology and for a bargain price of about US$75 million. Nasa's much larger Mars Atmosphere and Volatile Evolution mission, or Maven, which reached its position around the red planet on Sunday, cost nearly 10 times as much at US$671 million.

India celebrates Mars mission 'cheaper than a movie'

India’s prime minister Narendra Modi led nationwide celebrations yesterday after his country became the first in the world to succesfully send a satellite to Mars on a first attempt. The Mangalyaan satellite entered the red planet’s orbit on Tuesday evening, a day after the American MAVEN - Mars Atmosphere and Volatile EvolutioN - mission.

Projeto de Transformador utilizado em uma Planta de Plasma AUTOR Giancarlos Costa Barbosa UNIVERSIDADE FEDERAL DO RIO GRANDE DO NORTE CENTRO DE TECNOLOGIA PROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO-BRASIL

Abstract
The contamination of the environment is an issue that concerns all. The toxic waste is a major cause of contamination and a global solution to eliminate it is the use of thermal plasma. Currently, a toxic waste inertization plant is development. This plant is basically composed by a radio-frequency power supply (RF power supply) and an inductive plasma torch. As the power source and the torch have a difference in impedance, it is necessary to use a transformer. Thus, this work presents the methodology and the development of a medium-power transformer (50 kW) operating at high frequency (400 kHz), using software for calculating electromagnetic fields.
