### Transcript

• 1. DC Regulated Power Supply http://www.tradeindia.com/manufacturers/dc-regulated-power-supply.html
• 2. • An alternating current (AC) is an electrical current whose magnitude and direction vary cyclically,as sine wave. • Direct current (DC) or continuous current , whose direction remains constant. Its flow of current in streight line AC/DC POWER SUPPLY
• 3. AC/DC: What's the Difference? When direct current flowing,because it is running in streight line then it loose energy when it is flowing.in wires. However Ac current flowing in sine wave then it do loose energy,because at one time its cuurent state is 0 and one its current state is 1 so if it is loose energy then it is recover very easily.
• 4. How to compare AC and DC • AC voltage is usually expressed as a root mean square (RMS) value, written Vrms. For a sinusoidal voltage: Vrms is useful in calculating the power consumed by a load. If a DC voltage of VDC delivers a certain power P into a given load, then an AC voltage of Vpeak will deliver the same average power P into the same load if Vrms = VDC. Because of this fact, RMS is the normal means of measuring AC voltage.
• 5. AC/DC POWER SUPPLY Block-Diagramm
• 6. AC/DC POWER SUPPLY Circuit diagram :
• 7. Transformer: • Function: A transformer is a device used to increase (step up) or decrease (step down) the AC voltage in a circuit. • Properties: Laminated in order to reduce power losses through Eddy Currents. • Operation: The way transformers operate is based on the principle that an alternating current in the primary coil will induce an alternating electro- magnetic-field (EMF) on the secondary coil due to their mutual inductance.
• 8. What is happening inside a transformer? 1. Iron Core molecules before energizing. 3. Iron Core molecules line up after energizing. 2. Energizing the coil and thus magnetic flux generation.
