CHAPTER THREE ANALYSIS AND DESIGN 3.1 INTRODUCTION This chapter deals with the process of obtaining the design specifications of the wireless Frequency Modulated Transmitter with a frequency of 100MHz in a range of 100m under accurate conditions. From the block diagram shown in FIG. 2.1‚ various circuit components are now chosen and appropriate approximate values are now chosen to match its properties as well as perform duties of the stages. The entire system could be grouped into two major stages

Efficient Energy Harvester for Microbial Fuel Cells using DC/DC Converters Abstract— Microbial fuel cell (MFC) is an emerging technology for sustainable energy production. An MFC employs indigenous microorganisms as biocatalysts and can theoretically convert any biodegradable substrate into electricity‚ making the technology a viable solution for sustainable waste treatment or autonomous power supply. However‚ the electric energy currently generated from MFCs is not directly usable due to the low

Alternating Current Theory - J R Lucas An alternating waveform is a periodic waveform which alternate between positive and negative values. Unlike direct waveforms‚ they cannot be characterised by one magnitude as their amplitude is continuously varying from instant to instant. Thus various forms of magnitudes are defined for such waveforms. The advantage of the alternating waveform for electric power is that it can be stepped up or stepped down in potential easily for transmission and utilisation

A transformer is a static electrical device that transfers energy by inductive coupling between its winding circuits. A varying current in the primary winding creates a varying magnetic flux in the transformer’s core and thus a varying magnetic flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (EMF)‚ or "voltage"‚ in the secondary winding In electrical engineering‚ two conductors are referred to as mutual-inductively coupled or magnetically coupled [1] when

(up to 100kHz)‚ passive filters are generally constructed using simple RC (Resistor-Capacitor) networks‚ while higher frequency filters (above 100kHz) are usually made from RLC (Resistor-Inductor-Capacitor) components. Passive filters are made up of passive components such as resistors‚ capacitors and inductors and have no amplifying elements (transistors‚ op-amps‚ etc) so have no signal gain‚ therefore their output level is always less than the input. Filters are so named according to the frequency

Abstract—We focused on Buck/Boost Rectification by Single Phase Matrix Converter with fewer numbers of switches. The conventional matrix converter consists of 4 bidirectional switches‚ i.e. 8 set of IGBT/MOSFET with anti parallel diodes. In this proposed matrix converter‚ only six switches are used. The switch commutation arrangements are also carried out in this work. The gate pulses to the switches are provided by the PWM techniques. Step up or step down DC outputs can be obtained by using suitable
