CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless

Abstract : A DC power supply is very important in our day to day life. We use it to charge or operate our DC components like charger light‚ cell phone battery charger etc. It’s nothing but a AC to DC converter. Keywords: 5V DC power supply‚ rectifier‚ diode‚ filter‚ capacitor‚ zener diode‚ voltage regulator‚ signal‚ waveshape. 1. Introduction I’m designing a 5V DC power supply. Here I’m basically designing a AC to DC converter. To convert the AC to DC‚ I’m using components like full wave bridge

AUTO MUTE FOR AUDIO DECK (Automatically Mute Your Audio System when you receive a call) Muting car’s audio deck‚ while talking on cell phone is an important yet difficult task. This project is designed to solve the problem. A sensitive IR transmitter and receiver pair is designed and fixed to a cell phone holder. Always the cell phone should be placed in the holder. The transmitter unit continuously transmits IR rays. These IR rays are interrupted by the cell phone. Whenever the cell phone

current‚ I‚ is related to the charge‚ Q‚ of a voltage source‚ and is a function of time (Eq 3). The voltage drop across a resistor is IR (Eq 4)‚ where R is the resistance value. The voltage drop across a capacitor is Q/C (Eq 5)‚ where C is the capacitance value. The voltage drop across an inductor is L(dI/dt) (Eq 6)‚ where L is the inductance value. Also‚ the impressed voltage‚ E‚ is a function of time‚ and by Kirchhoff’s Second Law is equal to the sum of the voltage drops in
