CHAPTER 1 INTRODUCTION 1.1 GENERAL Nowadays‚ there is a demand of power supply. As an electrical engineer‚ it is necessary to design system with low cost‚ reduced losses and higher efficiency. This paper proposes nine-switch converter with single controller‚ rather than using 12 switches for operation of drives separately. In electrical vehicle drives mostly AC motors are used. It is because of its well known advantages like simplicity‚ reliability‚ lack of mechanical commutator

expensive‚ sophisticated equipment and are most often used in research settings. Currently the easiest and therefore most popular way to measure body composition is with a technique that measure current flow through the body‚ called bio electric impedance analysis. The two most commonly advanced reasons for the increase in the prevalence of obesity are certain food marketing practices and institutionally-driven reductions in physical activity‚ which we have taken to calling “the big two.” Elements

HIGH-VOLTAGE NEURAL STIMULATOR COMBINED WITH A LOW-VOLTAGE RECORDER Ulrich Bihr‚ Jens Anders‚ Joachim Becker and Maurits Ortmanns Institute of Microelectronics‚ University of Ulm‚ Ulm‚ Germany Ulrich.Bihr@uni-ulm.de Abstract: This paper presents a high-voltage (HV) neural stimulator combined with a low-voltage (LV) neural recorder. In many bidirectional neural implementations with a high voltage compliance for the stimulation is it not possible to have a high density due to the high power

Good sound is the foundation of any music venue. Poor sound can ruin the audience’s enjoyment of the concert. Good sound enhances a concert‚ creates interest‚ and commands attention. So I’ll make a review of the most important gear of the Live Sound Equipment and it’s different types. So let’s start with the mics as they are the first source to pick up an acoustic signal and transform it into electrical‚ which will be driven down via XLR cables to the mixing desk and back to the PA system and the
