  5. 7. More details... <ul><li>A device or system that supplies or other types of to an output or group of loads is called a power supply unit or PSU </li></ul>
  6. 8. Electrical power supplies <ul><li>A power supply may include a power distribution system as well as primary or secondary sources of energy such as: </li></ul>converting line voltage to a well-regulated lower-voltage
  7. 9. Electrical power supplies <ul><li>A power supply may include a power distribution system as well as primary or secondary sources of energy such as: </li></ul>
  8. 10. Electrical power supplies <ul><li>A power supply may include a power distribution system as well as primary or secondary sources of energy such as: </li></ul>Chemical And other forms of systems
  9. 11. Electrical power supplies <ul><li>A power supply may include a power distribution system as well as primary or secondary sources of energy such as: </li></ul>
  10. 12. Electrical power supplies <ul><li>A power supply may include a power distribution system as well as primary or secondary sources of energy such as: </li></ul>
  11. 13. Power supply types <ul><li>Battery power supply </li></ul><ul><li>A is a type of linear power supply that offers benefits that traditional line-operated power supplies lack: mobility, portability and reliability. </li></ul>
  12. 14. Power supply types <ul><li>Linear power supply </li></ul><ul><li>An powered linear power supply usually uses a to convert the voltage from the wall outlet (mains) to a different, usually a lower voltage </li></ul>
  13. 15. Power supply types <ul><li>AC/ DC supply </li></ul><ul><li>The power supply consisted of a rectifier and a capacitor filter </li></ul>
  14. 16. Power supply types <ul><li>Switched-mode </li></ul><ul><li>power supply </li></ul><ul><li>(SMPS) works on a different principle. AC mains input is directly rectified without the use of a transformer, to obtain a DC voltage. </li></ul>
  15. 17. Power supply types <ul><li>Programmable power supply </li></ul><ul><li>This type of supply is composed of a processor, voltage/current programming circuits, current shunt, and voltage/current </li></ul><ul><li>read-back circuits. </li></ul>
  16. 18. Power supply types <ul><li>Uninterruptible power supply </li></ul><ul><li>An uninterruptible power supply (UPS) takes its power from two or more sources simultaneously. </li></ul>
  17. 19. Power supply types <ul><li>High-voltage power supply </li></ul><ul><li>High voltage refers to an output on the order of hundreds or thousands of volts. High-voltage supplies use a linear setup to produce an output voltage in this range. </li></ul>
  18. 20. Power supply types <ul><li>Voltage multipliers </li></ul><ul><li>Voltage multipliers, as the name implies, are circuits designed to multiply the input voltage. </li></ul>
  19. 21. Power supply types <ul><li>Voltage multipliers </li></ul><ul><li>The input voltage may be doubled (voltage doubler), tripled (voltage tripler), quadrupled (voltage quadrupler), etc </li></ul>
