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

high-voltage port with port voltage V1 ‚ 240 V ≤ V1 ≤ 450 V‚ and a low-voltage port with port voltage V2 ‚ 11 V ≤ V2 ≤ 16 V; the rated output power is 2 kW. A much increased converter efficiency is achieved with the methods detailed in this paper: The average efficiency‚ calculated for different voltages V1 and V2 ‚ different power levels‚ and both directions of power transfer‚ rises from 89.6% (conventional phase shift modulation) to 93.5% (proposed modulation scheme). Measured efficiency values‚ obtained

significantly to global warming. This term refers to the measured increase in the Earth’s surface temperature since the late 19th century and the environmental effects of this change. The primary goal of developing green sources of energy is to generate power while minimizing both waste and pollution‚ to thereby reduce the impact of energy production on the environment. Scientists who advocate the use of green energy say that using such sources will reduce the rate at which climate change occurs‚ although

DEFINITION: An amplifier with two or more stages arranged in a manner that the output of one serves as the input for the next‚ while amplifying at each step. It is also called cascade amplifier. EXPLANATION: In most of the cases the gain provided by a single stage amplifier stage is insufficient. Consequently two or more amplifier stages are cascaded in order to increase the gain. Several amplifiers can be connected in a cascaded arrangement with the output of one amplifier driving the input of the

Nuclear Power Nuclear Power has always been a controversial and argumentative topic. Many people criticize Nuclear Power but it has its benefits by being a long term solution. Nuclear Power is reliable because it provides us with large power-generating capacity able to meet all needs. Additionally‚ Nuclear Power is safe because it releases less Carbon Dioxide emissions into the atmosphere then fossil fuels. Furthermore‚ Nuclear Power is eco-friendly because we can reduce waste by recycling

Finish Line & Beyond PO W E R SH A R I N G Power Sharing: Power sharing is the very spirit of democracy. A democratic rule involves sharing power with those affected by its exercise‚ and who have to live with its effects. All communities‚ social groups get their say in the governance. People have a right to be consulted on how they are to be governed. A legitimate government is one where citizens‚ through participation‚ acquire a stake in the system.
