supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another. An AC-DC power supply converts alternating current (AC) into the direct current (DC). In general most consumer electronic devices such as desktop computer‚ mobile phone require a low DC power source. In practical field DC power for electronic devices is most conveniently obtained from commercial AC lines by using

alternating current signal can be amplified on 4.5V central voltage. When using the operational amplifier with the negative feedback‚ the voltage of the positive input terminal and the voltage of the negative input terminal become equal approximately. This is called virtual grounding. So‚ by this bias voltage‚ the side of the positive and the side of the negative of the alternating current signal can be equally amplified. When not using this bias voltage‚ the distortion causes the alternating current signal

limited‚ it is sufficient to include only a reduced area in the optimisation problem. Here‚ such an optimal power flow problem is formulated where the considered area is defined using sensitivity analysis. To include N 2 1 security as an objective‚ a current injection method is applied‚ which facilitates the determination of the system state in the case of a line outage‚ without having to carry out a full-load flow simulation. 1 Introduction The overall goal of the power supply industry is to

Project Title: Why is Solar Power Better than Traditional Power? Solar Power might be a popularly growing technology today but the idea of its inception dates back to more than 175 years. It was in 1839 when Alexandre Edmond Becquerel discovered that certain materials produced small amounts of electricity on exposure to sunlight. Later‚ in 1876 William Adams along with Becquerel’s student Richard Day‚ discovered that selenium contained potential properties of converting light into electricity. The
