What is a power supply?

A key aspect to understanding a power supply is to recognize the difference between a power supply and a power source. These are not the same thing. The source supplies the electricity. This could be a battery, an outlet or a generator. The supply converts that power to the voltage and the format you need for your application.

What does a power supply do?

Power supplies may perform single or multiple functions. They can be used to alter the voltage up or down, regulate power or convert power to direct current. For your application, it is important to choose a power supply that performs all the necessary functions, so you avoid damaging the devices in use; however, some power supplies are more complicated and expensive than you need for your application. To choose the best power supply for your needs, consult with your local electrical experts.

How does a power supply work?

Power supplies are made up of several basic components. These will vary slightly based on the specific functions of a particular power supply. The following list includes information about a power supply and its basic components in Upland, CA:

  • Transformer: The transformer changes (transforms) incoming voltage to the desired level. It can raise or lower the voltage to suit the application.
  • Rectifier: This component converts the power from AC to DC. The rectifier may be bridge, full-wave or half-wave.
  • Regulator: When you’re dealing with electricity, surges and drops are possibilities. Since these can damage devices that are relying on the power supply, a regulator is used to reduce the amount of fluctuation in the voltage.
  • Filter: The filter helps smooth out waves generated by the process of converting AC power to DC power. It reduces the waves to protect the power supply and any devices using its associated electricity.
