Power supply is an electronic circuit that is used for providing the electrical power to appliances or loads suchas computers,machines,and so on. These electrical and electronic loads require various forms of power at different ranges and with different characteristics. So, for this reason the power is converted into the required forms (with desired qualities) by using some power electronic converters or power converters.


Electrical and electronic loads work with various forms of power supplies, such as AC power supply, AC- to-DC power supply, High-voltage power supply, Programmable power supply, Uninterruptable power supply and Switch-mode power supply.

What is Switch-mode power supply?

The electronic power supply integrated with the switching regulator for converting the electrical power efficiently from one form to another form with desired characteristics is called as Switch-mode power supply. It is used to obtain regulated DC output voltage from unregulated AC or DC input voltage.

Similar to other power supplies, switch-mode power supply is a complicated circuit that supplies power from a source to loads. switch-mode power supply is essential for power consuming electrical and electronic appliances and even for building electrical and electronic projects.
