Switching Power Supply Operation Principle and Design

Switching power supply operation is very different to that of linear power supply. Despite of its complexity, higher bill of material cost and higher parts count, switch mode power supply is still the preferred power supply topology in the market nowadays. The main reason is higher efficiency and higher power density. Higher efficiency simply means that only a small portion

How Switch Mode Power Supply Regulates its Output

In linear power supply design output regulation is not a question because it is easily done by the linear regulator inserted before the load. Nowadays linear power supply is not anymore widely used. What is drawing more attention now is the switch mode power supply. How switch mode power supply regulates its output is different from what linear regulator does.

Operation of a Switch Mode Power Supply

How a Switch Mode Power Supply Works? What is the operation of a switch mode power supply? A switch mode power supply works by continuously switching on and off a semiconductor switch. This semiconductor switch is can be a MOSFET or a BJT. The former is more popular than the latter. When the switch turns off, there is no current
