What is the Difference Between Power Source and Power Supply?

🆚 Go to Comparative Table 🆚

The main difference between a power source and a power supply lies in their functions and the energy transformations they perform. Here is a comparison of the two:

Power Source:

  • A power source contains energy to produce another form of energy, such as converting the kinetic energy of flowing water into electricity.
  • Power sources are used for the production of power and energy transformation.
  • Examples of power sources include electricity outlets, batteries, generators, and solar power converters.

Power Supply:

  • A power supply is an electrical device that provides electric power to an electrical load.
  • The main purpose of a power supply is to convert electric current from a source into the correct format and voltage needed to power the load.
  • Power supplies may be separate standalone pieces of equipment or built into the electrical devices they power.
  • They can be adjustable, regulated, isolated, or have other features depending on the specific requirements of the connected devices.

In summary, a power source is an origin of electricity, while a power supply is a device that converts and regulates the power from the source to meet the requirements of the connected devices.

    Here is a table that highlights the differences between power sources and power supplies:

    Feature Power Source Power Supply
    Definition A power source is a component that supplies electrical energy, such as a battery or a generator. A power supply is a device that converts one form of electrical energy to another, such as converting AC to DC or voltage levels.
    Types Power sources can be classified into two main types: AC and DC. AC power is typically supplied by power sockets or generators, while DC power can be supplied by batteries or power supply circuits. Power supplies can be categorized into linear and switching power supplies.
    Function Power sources are responsible for providing electrical energy to devices and systems. Power supplies are responsible for converting and regulating the electrical energy to ensure it is suitable for the devices it powers.
    Examples A battery is a power source that provides DC voltage. A power adapter is a power supply that converts AC power from a wall socket into DC power for a device.

    Please note that the search results provided did not directly address the differences between power sources and power supplies. The information in the table is based on the general knowledge of the topic.
