Title: Over Under Line Voltage Protection for Electrical Appliances Page Link: Over Under Line Voltage Protection for Electrical Appliances - Posted By: smart paper boy Created at: Thursday 28th of July 2011 01:36:23 PM	over voltage under voltage tripping mechanism pdf, an introduction on over and under voltage protection of electrical appliances, over under line voltage protection for electrical appliances ppt for free download, mobile controlled electrical appliances project materials, inurl pdf protection of electrical appliances, over and under main voltage protection circuit diagram, 3 phase under voltage protection ckt using lm324,
ABSTRACT: This circuit protects refrigerators as well as other electrical appliances from over and under voltage. By the name itself we can say that if the input voltage is more or less than the required voltage then the electrical appliance is turned off nothing but it gets disconnected from its respective power supply. This circuit uses an operational amplifier IC LM324 which is used as a comparator. Generally, the IC LM324 consists of four operational amplifiers, of which only two operational amplifi ....etc [:=Read Full Message Here=:]

Title: A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin 3 Voltage Stress Page Link: A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin 3 Voltage Stress - Posted By: seminar class Created at: Friday 13th of May 2011 12:43:33 PM	high and low voltage protector using ic, ppts in ieee format for high voltage engineering, voltage multiplier best seminar ppt, extra high voltage transmission line, high voltage topic for poster presentation, observation table for voltage input output in transistor as switch, to investigate the relation between input and output voltage,
A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches Abstract A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc [:=Read Full Message Here=:]



Title: Application of Voltage- and Current- Controlled Voltage Source Inverters for Distribu Page Link: Application of Voltage- and Current- Controlled Voltage Source Inverters for Distribu - Posted By: mattaparthi naga dinesh Created at: Saturday 09th of July 2011 02:29:47 PM	high voltage direct current seminar, voltage source inverter application projects, high voltage direct current transmission kr padiyar, applications of zero voltage crossing, atmega16 voltage source inverter, grid interfacing inverters, seminar voltage regu,
name dinesh 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 [:=Read Full Message Here=:]

EFFECTS OF VOLTAGE SAGS, SWELL AND OTHER DISTURBANCES ON ELECTRICAL EQUIPMENT AND THEIR ECONOMIC IMPLICATIONS ABSTRACT Poor power quality has come to stay in most parts of the world. In most part of Africa, especially in Nigeria, it is almost normal not to have good clean power free from disturbances. If power equipment and loads could talk or express feelings, I am sure they would have made a big protest against the great injustices imposed on them. A survey was carried out amongst 15 multi-nation ....etc [:=Read Full Message Here=:]

presented by: J.Chaithanya Bharathi A.L.Harika P.Divya Sree ABSTRACT The performance of any machine can be analyzed with reference to parameters like power factor, total harmonic distortion, voltage regulation, etc. These parameters alter when a machine is subjected to different loads. Depending on the load connected to the system, the voltage and current waveforms are varied. Due to the effect of harmonics, distortion of waveforms from sinusoidal to non sinusoidal is c ....etc [:=Read Full Message Here=:]
