Power conversion

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)
- DC to AC (inverter)
- AC to AC
- Voltage to current (current source)
Certain specialized circuits, such as the flyback transformer for a CRT, can also be considered power converters.
