For small power applications like on board power sources, linear power supply is often used due to its simplicity and low cost. However, when the need for high power density designs arises, linear power supply simply disappears in the picture. It is because linear power supply is very less efficient. Switch mode power supply comes in place. Switch mode power
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
Continue readingHow 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
