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

Security is the important cause in the modern world. Now a day so many schemes have announced by the banks which very attractive and the people are saving money in banks. At this point protecting the banks is the main duty of police. Hence police are appointed securities to the banks and make them to patrol during nights. . They have to go to every banks and streets and sign the books kept in their places .But some police people forgot their duty and will sleep in a vacant place and in the morning they get up and in a hurry go to these banks an ....etc

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

Problem Statement

Traffic Congessions are a major problem in all the metropolitan cities. One of the main causes for these congessions is improper setup of wait times at the signals of major junctions. It is often observed that the traffic police change the timing of each of the signals randomly based on the traffic on each of the routes at the junction or even sometimes they switch to managing the traffic manually after switching off the signals completely.

There is a requirement to understand the traffic flows at all the major junctions ....etc

A variable power supply technique for use with a high efficiency line driver uses a signal peak amplitude to determine a start of a rise time for a power supply to begin supplying operating voltage to the line driver. This ensures that the voltage supplied to the line driver essentially tracks the output signal.

A slew start delay circuit detects when the signal rises above a level that can be supported by a current power supply, and determines a variable delay for switching on a power supply to supply a higher voltage to the line driver. Th ....etc
