Power conversion

From Free net encyclopedia

Power conversion is the process of converting power from one form into another. This could include electromechanical or electrochemical processes.

In electrical engineering, power conversion has a more specific meaning, namely converting electric power from one form to another. This could be as simple as a transformer to change the voltage of AC power, but also includes far more complex systems. Power conversion systems often incorporate redundancy and voltage regulation.

Typical types of conversion include:

• DC to DC
• AC to DC (power supply)
  • Rectifier
  • Switched-mode power supply
• DC to AC (inverter)
• AC to AC
  • Transformer/autotransformer
  • Voltage regulator
• Voltage to current (current source)

Certain specialized circuits, such as the flyback transformer for a CRT, can also be considered power converters.
