introduction
Digital thermometer is a good choice for beginners who just left the world of microcontrollers, because it provides an opportunity to learn using sensors to measure real world signals are analog in nature is. This article describes the project as based on microcontroller and temperature sensor LM35 PIC16F688. Is analogous to the LM35 sensor that converts the temperature to a proportional analog voltage. The output signal from the sensor is connected to one of the inputs of the ADC in a PIC16F688 microcontroller to obtain an equival ....etc

Power System Fault Analysis using Fault Reporting Data

INTRODUCTION

Any abnormal conditions which causes flow of huge current in the conductors or cable through inappropriate paths in the circuit can be defined as a fault. In normal operating conditions all the circuit elements of an electrical system carry currents whose magnitude depends upon the value of the generator voltage and the effective impedances of all the power transmission and distribution system elements including the impedances of t ....etc

REGULATED POWER SUPPLY
1.1 Types of Power Supply
There are many types of power supply. Most are designed to convert high voltage AC mains electricity to a suitable low voltage supply for electronic circuits and other devices. A power supply can by broken down into a series of blocks, each of which performs a particular function.
For example a 5V regulated supply:

Each of the blocks is described in more detail:
Transformer- steps down high voltage AC mains ....etc

This article is about a simple 0-100 C digital thermometer with 1 C resolution using 8051. The circuit is based on LM35 analog temperature sensor, ADC0804 and AT89S51 microcontroller. LM35 is an analogue temperature sensor IC which can measure a temperature range of -55 to 150 C. Its output voltage varies 10mV per C change in temperature.

For example, if the temperature is 32 C, the output voltage will be 32 x 10mV = 320mV. ADC 0804 is used to convert the analogue output voltage of the LM35 to a proportional 8 bit digital value suitable ....etc

mini projet report
Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc
